Cosmetic Dentistry Procedures: Teeth Whitening
Whitening of the teeth is performed for patients who desire a brighter smile. Tooth whitening can be performed to reduce discoloration and staining, or simply to provide the patient with whiter, brighter teeth.
We've prepared a primer on teeth whitening to help improve your understanding of what teeth whitening can and do for a patient. Just click on the next page graphic below to get started. Or, if you want to jump to a specific topic, use the handy outline.
How white can your teeth become?
How white your teeth can become from bleaching and whitening is a common question with a very subjective answer. Some whitening procedures claim they can whiten your teeth by up to nine shades, but that is highly unlikely. Just a change of two or three shades will make a significant difference in just about anyone's smile. There is no one standard system in the dental field to measure and determine tooth color. The most often heard about, however, is the Vita shade guide. This guide divides tooth color into four basic shade ranges:
A (reddish brown)
B (reddish yellow)
D (reddish gray).
In the A range there are five levels of darkness. Ranges B, C and D, each have four levels.
Not all of your teeth are the same natural color. Usually your eye teeth tend to be darker than the others, your front teeth are typically the whitest, and molars tend to be a shade between the two. The goal for everyone is to achieve their individual optimum whiteness while still looking natural. During your first consultation for tooth whitening, your dentist will go over what you personally can expect for your specific smile. How white teeth will become from a given procedure will vary from person to person. The structure of your teeth and the type of procedure implemented will affect the outcome.
The following chart will give you some idea of how to compare the two most popular methods for tooth whitening. As everyone's circumstances are different, both options should be further discussed with your cosmetic dentist prior to making a decision.
Procedure Usually Lasts For: May Cause During and Shortly After Procedure: Time for Procedure: Changes in Shade: Average Cost:
Gel/Tray 4 - 12 Months Sensitive Gums/Teeth 50 Hours 4 - 5 $ 400.
Laser 12 - 18 Months Minor Discomfort 2 - 3 Hours 7 - 8 $ 1,000.
BriteSmile 12 - 18 Months Minor Discomfort 2 Hours 8+ $ 600.
Overview of Teeth Whitening
Teeth whitening is used to correct discoloration of the teeth by removing the brown and yellow staining. The term "teeth whitening" can refer to a number of techniques to improve the brightness of the patient's teeth. Among them are chemical whitening, mild acid whitening, abrasive teeth brightening and the newest technique, laser teeth whitening.
Teeth bleaching is chemical process used to lighten the color of the patient's teeth. The procedure can be performed entirely in the cosmetic dentist's office or it can be performed by the patient in their home, using a materials provided by the dentist. The home method is often used because it saves the patient from having to make an office visit for each treatment.
Before the patient embarks on the home teeth whitening regimen, the cosmetic dentist creates a custom mouth tray for the patient. The custom tray is a critical component of the treatment. It ensures that the correct amount of whitening solution is used and that the patient's teeth are properly exposed to the whitening solution. The custom made mouth tray provides for a better fit than a one-size-fits-all mouth tray to help increase the margin of patient safety.
The steps in the home teeth whitening regimen are fairly straightforward. The cosmetic dentist's office provides the patient with the materials and instructions and also answers questions the patient may have about the routine. Your dentist's office can also provide you with off-site supervision should you have any questions once you've begun.
A home whitening session can last for two to three hours, during which time you will have the tray and solution in your mouth. Depending upon your needs and desired results, your dentist may instruct you to keep the tray in your mouth overnight. Typically, you will follow your home teeth whitening regimen for two to three weeks, after which time you will return to your cosmetic dentist for a follow up visit.
What causes discoloration of the teeth?
Teeth enamel discoloration can be caused by staining, aging, or chemical damage to teeth. Some of the more common causes of teeth discoloration are medications, coffee, tea or cigarettes. People who drink significant amounts of cola soft drinks can experience similar staining.
Aside from staining, there are other factors that can affect the color of an individual's teeth. Genetics can play a role. Some people have naturally brighter enamel than others. Disease can also be a factor and certain medications can cause a discoloration of the teeth. If you suspect that there is an underlying medical cause for your teeth discoloration, be sure to inform your cosmetic dentist.
COSMETIC GUM SURGERY
What is cosmetic gum surgery?
Your gum tissue is like a frame that provides form and shape to the top of your tooth. A less than attractive smile results when the integrity of the gum is compromised or the actual gum between your teeth becomes weak. Usually due to poor hygiene (gum disease), you actually begin to lose gum tissue. Cosmetic dentistry provides many cosmetic solutions such as composite resin bonding, crowns, and veneers to create a great smile. These solutions are usually part of an overall strategy which may involve cosmetic gum surgery. Used to correct a 'gummy smile' (a significant portion of your gum is exposed when you smile), cosmetic gum surgery is the procedure of lengthening your teeth from the neck of the tooth upwards. Your teeth then appear to be longer and much less gum is seen when you smile.
The "Long in the Tooth" Smile - Cosmetic gum surgery, or periodontal plastic surgery, can correct almost any deformity or gingival problems preventing you from a beautiful smile. As we age, our gums may shrink and recede which makes our teeth look longer. While this is often age-related, it can also occur due to a bad bite. A cosmetic dentist or a periodontist can correct this to such an extent, that you'll have a very youthful appearing smile.
The "Gummy Smile" - This is a problem where your teeth appear to be too short. Gum sculpting is often the solution. To solve this, a dentist uses a laser to remove the excess tissue of your "gummy" smile, which then exposes more of your tooth.
How much does cosmetic gum surgery cost?
The costs involved in cosmetic gum surgery vary extensively based upon how much of your mouth is undergoing a procedure, which corrective procedure is being used, and which other cosmetic dentistry procedures will be needed to provide you with that perfect smile. It is common for other cosmetic dentistry procedures, such as crowns or veneers, to be recommended by your dentist as part of the overall strategy to cosmetically correct your gums. The overall strategy should be extensively discussed with your dentist and well understood by you prior to undergoing these procedures..
Types of Root Canals
There are generally two types of root canal procedures. The first (and hopefully only) root canal on a tooth, and the second root canal on the same tooth. Both procedures are the same, other than that if this is the second root canal done on the same tooth it requires more time and expense. This is because your dentist must remove all of the previous filling in the canal and pulp area in order to start again.
Pros and Cons of Dental Root Canals
Advantage: Pain is always associated with root canals, but should actually be little to no pain during the procedure. The procedure is not for cosmetics, but rather your health. The infect will only get worse with time if left untreated. The root canal procedure is successful over 92 percent of the time. The biggest advantage is that the tooth will not need to be extracted in the future.
Disadvantage: Not often, but sometimes infected tissue is pushed through the ends of the root, which will infect the gum. This is easily treated, but is also painful until the infection is cleared up. Canals are irregularly shaped, and if the canal is not accurately measured or branches of the canal were not discovered, it cannot be completely cleaned or filled requiring the procedure to be done again when this area becomes infected.
Overview of Tooth Veneers
Often an alternative to crowns, veneers are very thin pieces of specially-shaped porcelain or plastic that are glued over the front of your teeth with little or no anesthesia needed. They are the cure for teeth that are severely discolored, chipped, have small holes or pits, misshapen or crooked, or for the correction of unwanted or uneven spaces. Unlike crowns, veneers won't require the dentist to remove much of the tooth itself in most cases. It is important to ask your cosmetic dentist how much tooth will be removed. In some cases more tooth will need to be removed, which may increase the risk of trauma to the tooth. Veneers are created from an impression taken in your cosmetic dentist's office. Your custom veneer is then glued directly onto your tooth. Typically costing less than crowns, veneers won't stain, making veneers a very popular solution for many people seeking that perfect smile. Strong and very durable, veneers last from ten to fifteen years, and come in colors that will brighten dark teeth without the worry of them changing color.
How are Tooth Veneers Attached to your Tooth?
In your first appointment, it is important to initially discuss with your cosmetic dentist that you will want to "try in" your veneers with temporary cement that is the same color cement as will be used for the permanent attachment. During this "try-in" phase, be sure to look at your veneers in natural light in addition to the office light. Teeth are prepared for veneers by lightly buffing to allow for the small added thickness of the veneer. Veneers are thin like contact lenses, and will usually only need tooth reduction of 0.5mm to 1.0mm. If a drastic change is being made for the result you want, reduction may be 1.0mm to 2.0mm. A mold is taken of the teeth, from which the veneers are modeled after. Temporary veneers will be placed and worn until your permanent veneers are ready. While wearing the temporary veneers, advise your cosmetic dentist of any adjustments or changes you would like made, such as in shape or size. These changes will be translated into your permanent veneers, so good communication between you and your dentist is important in achieving your new smile.
Your dentist places the veneers with water or glycerin on the teeth to verify their perfect fit and the shade or color. The color cannot be changed after the veneers are adhered to your teeth. The tooth is then cleansed with chemicals to achieve a durable bond. Once the glue is between the veneer and your tooth, a light beam is used to harden the glue/cement.
Pros and Cons of Tooth Veneers
Porcelain veneers are common in creating new smiles and smile makeovers. With porcelain veneers, you can have the smile of your dreams in a very short period of time. Typically veneers are difficult to stain, making veneers a very popular solution for many people seeking that perfect smile. Strong and very durable, veneers last from ten to fifteen years, and come in colors that will brighten dark teeth without the worry of them changing color. Veneers are typically done in only two one and a half hour long appointments, and can actually strengthen your tooth.
There is no additional maintenance, other than a follow-up visit to your cosmetic dentist and proper brushing and flossing on a daily basis.
Finally, a whiter smile gives people to whom you are speaking a place to focus on and gives you a friendlier appearance.
It takes roughly a week or two of a period of adjustment to get used to your teeth that have been changed in color, size, spacing and shape. While very little tooth is removed in most cases, there are situations where more tooth must be removed which increases the risk of trauma to the tooth. The amount of tooth to be removed for the veneers should be discussed with your cosmetic dentist beforehand.
It is common to have minor sensitivity after your teeth have been prepared for your veneers while wearing the temporary veneers. Some people can experience a difference in speech, usually pronouncing "s" and "f" sounds. This is corrected through minor adjustments your cosmetic dentist can make to your veneers. Veneers are very reasonable facsimiles of natural teeth, but not perfect replacements for natural teeth. It's common to see slight variations in the color of veneers upon very close inspection, as with natural teeth. It can take up to a month or two before your new smile feels a part of you.
If you suffer from bruxism, clenching or grinding of your teeth, veneers can be damaged, chipped or cracked from this. If you suffer from bruxism, speak with your cosmetic dentist about wearing a mouth guard at night to protect your new smile.
Who is a candidate for tooth contouring and reshaping?
If you want your teeth to appear less crowded, lack chips and fractures, have decreased overlaps or to be without pits or grooves in the enamel, this procedure should be discussed with your cosmetic dentist. With a little dental contouring, you can make a huge difference in the way you feel about your smile. Good cosmetic dentistry can give you a smile that is the envy of others. Tooth contouring by a cosmetic dentist does require that you have normal, healthy teeth.
Tooth reshaping, or tooth sculpting, is a safe and conservative way to improve your smile. Teeth may become weaker if large amounts of enamel are removed, tooth reshaping should be limited to minor changes or combined with veneers or bonding for the best smile.
Types of Tooth Contouring and Reshaping Procedures
There are actually several ways to change the appearance of your teeth. Many times these various procedures are combined in different ways to deliver that smile of your dreams.
Tooth Contouring and Reshaping
The reshaping of a your teeth is a procedure that involves the removal of a very small amount of tooth structure to help achieve a more desirable smile. Chipped or fractured areas are smoothed out and specific angles or edges can be rounded or squared. Contouring creates better alignment and can create a more feminine or masculine smile. It is sometimes done to prevent chipped areas from getting worse. Tooth reshaping is a conservative way to improve the teeth. Since teeth can become weaker if large amounts of enamel are removed, this procedure is limited to minor changes or combined with veneers or bonding for a terrific smile.
Veneers are sometimes used in conjunction with contouring. Dental veneers are very thin pieces of specially-shaped porcelain or plastic that are glued over the front of your teeth with little or no anesthesia needed. They are the cure for teeth that are severely discolored, chipped, have small holes or pits, misshapen or crooked, or for the correction of unwanted or uneven spaces. Unlike crowns, veneers won't require the dentist to remove much of the tooth itself. Veneers are created from an impression taken in your cosmetic dentist's office. Your custom veneer is then glued directly onto your tooth.
Basically, bonding will cover any natural flaws applying a thin coating of a plastic material on the front surface of your teeth. After this, your cosmetic dentist will apply a bonding material sculpt, color and shape it to provide a pleasing result. A high-intensity light then hardens the plastic, and the surface is finely polished. This procedure often accompanies contouring and teeth reshaping procedures.
How much does tooth contouring and reshaping cost?
Your dental insurance is likely to cover tooth contouring and reshaping only if it is needed as a result of an accident, but this is a relatively inexpensive procedure. The cost depends on how much the dental reshaping is needed, but average costs are approximately $50 to $350 per tooth.
Pros and Cons of a tooth contouring and reshaping
Your dentist can remove only a small amount of tooth enamel, contouring your problem tooth into a more pleasing shape for an improved smile. The tooth contouring procedure is quick, simple, painless, and inexpensive.
There are limits. You may be at risk for tooth breakage and decay if too much enamel is removed your teeth. If your teeth were uneven because you grind them, they'll become uneven again until the grinding issue is resolved. Your dental insurance is likely to cover tooth contouring and reshaping only if it is needed as a result of an accident.
What are dentures?
Dentures are removable replacements for missing teeth typically made out of an acrylic resin which at times incorporate porcelain or metal for additional structural support. There are two main types of dentures. Both Complete Dentures and Partial Dentures are finely crafted, custom-fitted. If you properly maintain your dentures they will appear natural and provide a perfect smile. Additionally, dentures help strengthen muscles controlling your expressions that require the support of your teeth, rid you of pronunciation problems caused by missing teeth and aid with chewing.
These replace all of your teeth, upper or lower. Their comfort depends on muscle, bones, tongue, and saliva. Patients begin wearing conventional dentures after healing the teeth that were pulled.
Immediate Dentures are placed all at once, and may require additional adjustments after the healing process. It can take months for your bone and tissue to stabilize after tooth extractions.
Upper Dentures, tend to be a bit easier to adjust to. These are made of the same materials as a Complete Denture, but are designed to provide you with upper teeth only.
Over Dentures are a type of conventional denture similar to Complete Dentures. The difference is that not all teeth are extracted and they use one or more natural teeth for their support. This type provides greater stabilization during chewing. Over Dentures cost more and typically require more preparation dental appointments until the procedure is fully complete.
Designed to correct the gaps in your smile when only some of your teeth are missing. Metal attachments anchor the dentures to your natural teeth. Partial Dentures maintain tooth alignment by preventing your remaining teeth from shifting. Partial Dentures can also help prevent your loss of more teeth due to decay or gum disease.
Pros and Cons of a Dentures
Dentures definitely provide a great smile with a very natural appearance. They're made of very durable materials and last very long when properly taken care of. Typically dentures last from five to ten years. They also correct several problems, from speech to chewing, for many patients.
There's no doubt that dentures take a little getting used to. There is maintenance involved, and initial speech issues to overcome (these are temporary and last only a couple of days). Mouth irritation or sores may occur, but are usually caused by poor dental hygiene, and not removing your dentures when needed. It is common that your mouth change over the life of your dentures, so even though they last long, they may need to be replaced to achieve a better fit before they are worn out. With a denture a person typically chews at only 15-23% efficiency compared to a person chewing with their natural teeth. In the case of a full upper denture, the upper palate is covered which can reduce taste of foods you're chewing.
What are Tooth Caps?
Grinding of your teeth, an improper bite, age, fillings and tooth decay can all be contributing factors in the wearing down, cracking or breakage of your teeth. Dental caps cover the entire visible surface of your affected tooth and add strength, durability and stability.
Who is a candidate for dental caps?
If you grind your teeth, have an improper bite, have fillings or tooth decay you have contributing factors to the wearing down, cracking or breakage of your teeth. Dental caps cover the entire visible surface of your affected tooth and add strength, durability and stability.
A cosmetic dentist will usually be able to identify problem areas in your mouth that might lead to tooth damage and a need for caps. Chewing patterns play a big role too. By selectively grinding the tips of your middle and back teeth (cusps) will alter your bite to reduce the stress on your at-risk teeth.
How much do dental caps cost?
Porcelain caps cost more because they are usually more time-consuming than gold caps. Porcelain and gold caps will average between $500. to $3,100. in total cost.
The relatively new reinforced resin or bonded all-porcelain type of caps cost more, and may exceed your insurance plan coverage for caps.
Usually, the price of dental caps increases with the number of in-office treatments required by the patient. Dental insurance does not typically cover all the costs of the dental cap procedure.
Pros and Cons of Dental Caps Types
Dental caps in general add a good deal of strength to a weakened or worn tooth, and last ten to fifteen years. Depending on your habits and the condition of your gums, there may be some drawbacks for you. Your cosmetic dentist will advise which is best for you given several factors, such as how important appearance is to you. The following are the advantages and disadvantages of the most common types of caps.
Advantage: The preparation of your tooth for a gold cap is the simplest and least complicated preparation. There is minimal tooth structure removal with as much as possible of the healthy tooth structure remaining untouched. As porcelain is hard by comparison, it may cause wear on opposing teeth over the years where gold is not as likely to do this. Gold is also easier to place to the area where the tooth and cap meet for a better fit. Gold is also a healthier environment for the gum tissue.
Disadvantage: The biggest disadvantage to gold caps is cosmetic, unless it is being used in the back of your mouth.
Advantage: Porcelain caps or the new reinforced resin types are considered to be the most aesthetically pleasing, as it is so easily matched in color to your surrounding teeth.
Disadvantage: The thickness of the porcelain required for pleasing aesthetics also requires that more tooth structure is removed. Also, it is more difficult for your cosmetic dentist to get an ideal fit where your gum meets the cap. Gingival inflammation is typically more common with porcelain caps than gold caps.
Porcelain Fused-to-Metal Caps
Advantage: Porcelain fused-to-metal caps have a very natural and pleasing appearance.
Disadvantage: They have a metal substructure and require an opaque below the porcelain, which can make the translucency of natural teeth difficult to replicate. Occasionally a darker line will be visible at the edge of the cap, by your gum as your gum recedes with age.
What are dental implants?
Dental implants are fixtures of titanium which are surgically screwed into your jaw bone. The implant is an anchor for a naturally-appearing false tooth or a set of false teeth. The success rate of dental implants depends on where the implants are placed and their purpose. They are typically best placed in the front portion of your lower jaw. Implants are great for replacing missing teeth. It is important that you have enough bone in the area of the missing teeth for the implants to be attached to. Implants are not only used to replace one tooth, but rather people missing most, if not all, of their teeth benefit greatly as well. Implants are increasingly being used to replace certain types of bridges and removable partial dentures.
Types of Dental Implant Procedures
Implants rely on titanium fixtures inserted into the jawbone. Most implants are made of titanium, which is very effective at fusing with living bone (osseointegration). There are three types of dental implants which your cosmetic dentist will discuss with you:
Root Form Implant
This screw type implant is shaped like the root of a tooth. This is the most commonly used implant and is used where there is plenty of width and depth to your jawbone. If your jawbone is too narrow or short for placement of the Root Form implants, bone grafting may be needed to allow for their placement. After you've received anesthesia, your cosmetic dentist will expose an area of your jawbone and prepare the bone for the implant. The number of incisions and bone preparations depend on how many implants you need. The implant will be set into place and your gums are closed with stitches. It will take three to six months for healing. After you've fully healed, your implant is uncovered and an abutment is attached.
Plate Form Implant
If your jawbone is too narrow for bone grafting, a Plate Form implant is placed into your jawbone. The Plate Form implant is unique for this purpose as it has a flat and long shape for a better fit into a narrow jawbone. After you've received anesthesia, your cosmetic dentist will expose an area of your jawbone and prepare the bone for the implant. The number of incisions and bone preparations depend on how many implants you need. The implant will be set into place and your gums are closed with stitches. It will take three to six months for healing (some Plate Form implants are immediately ready for restoration without the long healing process).
If there's not enough bone width or height for the Root Form or Plate Form implants, the Subperiosteal implant is recommended. The Subperiosteal implant is custom made to rest on top of your jawbone and under your gums like the Plate Form implant, but the Subperiosteal implant is placed through one of two special methods.
The first method of placement involves your cosmetic dentist making an impression of your jawbone. After you've received anesthesia, your cosmetic dentist exposes your jawbone and takes an impression of it. The impression is used by a dental laboratory to make a custom-fit implant for your jaw. The next procedure, after your custom-fit implant is created, is to again expose your jawbone and place the implant. Your gums are then closed with stitches and replacement teeth are installed.
The second method of placement requires a CAT scan of your jawbone. Through computer modeling techniques, a model of your jawbone is made from the CAT information. The next procedure, after your custom-fit Subperiosteal implant is created by a dental laboratory, is to again expose your jawbone and place the implant. Your gums are then closed with stitches and replacement teeth are installed.
How much do dental implants cost?
Dental implants can be a costly procedure. An entire team of professionals are needed to deliver a long-lasting smile. Implant procedures demand a great deal of the doctor's and staff's time and effort. The prosthodontist intensely studies your health profile, and then develops a plan to meet your unique needs. Additionally, surgical staff and the laboratory perform several services to produce the desired result. The materials used to construct implant prosthodontics are also very expensive. Bone grafting, if needed, is additionally costly.
While a basic implant is typically $1,250. to $3,000., depending on your circumstances additional costs for things such as in the case of a posterior mandible, bone regeneration, sinus elevation, and wide diameter or narrow diameter implants quickly escalate to as much as $15,000 to $30,000. for the complete procedure for the upper or lower jaw.
Pros and Cons of Tooth Bonding
Advantages of dental bonding:
Esthetics is the big advantage over silver fillings. As silver does not stick to teeth, entirely healthy tooth structure is usually removed to keep a silver filling in place. Composites permit your cosmetic dentist to remove only the decayed area of your tooth. Unlike silver fillings, composite bonding expand just like your teeth and are much less likely to cause cracks in your tooth. Composites bond directly to the tooth providing support. Composites can be used to fill in cracks, chips and gaps - and will match the color of your other teeth.
Disadvantages of the dental bonding procedures:
Bonding with composites simply costs more in material and time.
Who is a candidate for dental bridges?
If you have missing teeth and have good oral hygiene practices, you should discuss this procedure with your cosmetic dentist. If spaces are left unfilled, they may cause the surrounding teeth to drift out of position. Additionally, spaces from missing teeth can cause your other teeth and your gums to become far more susceptible to tooth decay and gum disease.
How much do dental bridges cost?
The average cost of a single fixed bridge depends on many factors, from which region you're in to how many and which type of bridges are needed. Typically dental bridge cost ranges from $500-900 per tooth. Dental insurance typically pays for about half of the cost of the bridge.
Who is a candidate for Tooth Crowns?
Grinding your teeth, an improper bite, age, fillings and tooth decay can all be contributing factors in the wearing down, cracking or breakage of your teeth. Dental crowns cover the entire visible surface of your affected tooth and add strength, durability and tooth stability.
Your cosmetic dentist will usually be able to spot problem areas in your mouth that might lead to tooth damage and a need for crowns. Chewing patterns play a big role as well. By selectively grinding the tips of your middle and back teeth (called cusps) will alter your bite to reduce the stress on at-risk teeth.
In other instances, crowns are used to replace a actual missing tooth. These crowns are anchored to the teeth on either side, with a bridge section connecting the two crowns. Instead of bridges, single tooth dental implants may be used that eliminate the need for supporting the crowns.
How are Tooth Crowns Attached to your Tooth?
Your cosmetic dentist will make an impression of the tooth and a dental laboratory will create the crown. You will typically leave the office with a temporary crown to wear while the permanent crown is being made - this takes about two weeks. The permanent crown is then cemented onto your tooth. Typically, only two visits are required for this part of the procedure. Often, a preliminary restoration of your tooth may be needed before a crown can be placed. To stabilize your tooth, a filling must first be put in place prior to placing a crown due to the loss of original tooth structure. Tooth crowns usually last ten to fifteen years.
Be sure to discuss with your cosmetic dentist that the cement color used for your permanent crown will be the same as used for your temporary crown. A try in paste is used for this purpose. The color of the cement does affect the overall color of a porcelain crown, so this needs to be discussed long before your temporary crown is placed.
In some cases your cosmetic dentist may choose to use a Flipper instead of a temporary crown. A Flipper is a false tooth to temporarily take the place of a missing tooth before the permanent crown is placed. A Flipper can be attached via either a wire or a plastic piece that fits in the roof of your mouth. Flippers are meant to be a temporary solution while awaiting the permanent crown.
Types of Tooth Crowns
There are basically three types of crowns, those made of gold, ceramic crowns and ceramic-veneered gold crowns. Gold and metal-ceramic crowns are extremely durable and are normally used in molars, where the forces from chewing and grinding are most prevalent. Ceramic crowns are used primarily for front teeth, since they can best resemble the natural tooth color.
Resin and Porcelain Crowns
The new reinforced resin or bonded all-porcelain type of crown has the nicest appearance. This crown can be made from pure ceramic or a new reinforced composite resin, and is almost indistinguishable from natural teeth. The new bonding technology involved provides an exceptional bond your tooth. It is metal-free, and thus satisfies the needs of patients with metal sensitivities. When correcting your back teeth with bonding, the cosmetic dentist will perform a tooth colored onlay. This type of procedure is used to correct only those parts of the tooth that are in need. This is a metal-free procedure.
Crowns Made of Gold
Gold crowns are appropriate when appearance is not a priority to you. The gold metal is extremely workable making gold crowns a more precise fit than any other type. While there exists a slight possibility of chipping with porcelain crowns, gold crowns provide no such possibility.
Porcelain and Metal Crowns
For a very natural appearance, porcelain fused to metal crowns are the answer. However, they have a metal substructure and require an opaque below the porcelain. This can make the translucency of natural teeth difficult to replicate. Occasionally a darker line will be visible at the edge of the crown, near to your gum when it recedes with age.
Types of Porcelain
There are basically two types of porcelain you're likely to hear and read about most - the felspathic and pressed ceramic porcelains. The felspathic type is the original method that has been around for 20 years. A Ceramist in a dental lab bakes porcelain onto tin foil and then heats it in an oven. The Ceramist is able to create tints and opaques inside the porcelain to give the natural look we seek.
Pressed ceramic is created from a single ingot. The single ingot is milled in one piece to create the desired shape. The stains and opaques are applied only to the surface of the porcelain to give a natural look.
Pros and Cons of Dental Crowns Types
Tooth crowns in general add a good deal of strength to weakened or worn teeth. Depending on your habits and the condition of your gums, there can be some drawbacks. Your cosmetic dentist will advise which is best for you given many factors, including how important appearance is to you. The following are the advantages and disadvantages of the most common crown types.
Advantage: The preparation of a tooth for a gold crown is the simplest and least complicated preparation as there is minimal tooth structure removal with as much as possible of the healthy tooth structure remaining untouched. While porcelain is hard by comparison, it may cause wear on opposing teeth over the years where gold is not as likely to do so. Gold is also easier to fit to the area where the tooth and crown meet for a better fit. Gold is also a healthier environment for the gum tissue.
Disadvantage: The biggest disadvantage to gold crowns is the cosmetic aspect, unless it is being used in the back of your mouth.
Advantage: Porcelain crowns or new reinforced resin are considered to be the most aesthetically pleasing, as it is so easily matched in color to the surrounding teeth.
Disadvantage: The thickness of the porcelain required for pleasing aesthetics also requires that more tooth structure needs to be removed. It is more difficult for your cosmetic dentist to get an ideal fit where your gum meets the crown. Gingival inflammation appears to be more common with porcelain crowns than gold crowns. All-porcelain crowns require a higher skill level from your dentist and lab.
Porcelain Fused-to-Metal Crowns
Advantage: Porcelain fused-to-metal crowns have a very natural appearance.
Disadvantage: They have a metal substructure and require an opaque below the porcelain. This can make the translucency of natural teeth difficult to replicate. Occasionally a darker line will be visible at the edge of the crown, near to your gum when it recedes with age.
