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.
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.
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.
There are a few teeth whitening procedures available that correct discoloration of the teeth by removing the brown and yellow staining. While each work effectively, there are advantages and disadvantages to each procedure dependent upon your objectives and commitment to the processes. The type of procedures available should be discussed with your cosmetic dentist, and a they will recommend the most appropriate teeth whitening procedure for you.
LASER BLEACHING (In-Office)
Using a laser with a whitening gel, this is an in-office bleaching system. The translucent bleaching gel is applied to the teeth and a laser light is used to activate the crystals to absorb the energy from the light and penetrate the teeth enamel to increase the lightening effect on the teeth. The length of time in the cosmetic dentist's chair depends on the degree of discoloration you have.
Advantage: One visit is usually all it takes for a bright smile.
Disadvantage: The sudden change of color is likely to be noticed by those around you immediately. This is the more expensive of the procedures available, but also the quickest.
Who is a candidate for cosmetic gum surgery?
You should consult your dentist about cosmetic gum surgery if you believe you have "Gummy Smile" (small crown length), gum recession "long teeth", an uneven gum line due to "short teeth", gum loss or gums which appear to be collapsing (from missing teeth), dark or black areas between bridges, implants, crowns or teeth, or tooth sensitivity from receding gums.
There are two primary procedures for cosmetic gum surgery, depending on your current smile.
"Gummy Smile" (Excessive Gingival Display)
A "Gummy Smile" can occur due to wear of teeth from teeth grinding, a short upper lip, or having a longer than usual upper jawbone. This smile is when your teeth appear too small and your gums appear to large.
"Long Tooth Smile" (Gum Recession)
As your gums recede, your teeth appear longer than normal. While "long teeth" may result in an unattractive smile, you should also be concerned with root sensitivity and possible tooth loss. Recent advances in techniques and materials have resulted in significant improvements in both comfort, predictability and esthetics.
To Correct a "Gummy Smile"
Cosmetic gum surgery can be done to reduce the excess gum and bone. The removal of these tissues allows for normal sized teeth and for a normal gum line appearance by using an instrument, usually a laser, to remove the undesirable tissue. Typically your cosmetic dentist will prescribe an antibacterial mouth rinse to be used twice a day for a two-week period following your surgery.
To Correct a "Long Tooth Smile"
As your gums recede, your teeth look much "longer" than normal. Such gum recession exposes your sensitive root surface which often makes hot or cold foods and drinks a painful experience. Teeth can become loose as your gum recedes. The cosmetic gum surgery solution is basically when a cosmetic dentist or periodontist removes tissue from the roof of your mouth and then grafts it onto your gum line. This tissue then reinforces thin gums or fills in areas where your gums have receded. Typically your cosmetic dentist will prescribe an antibacterial mouth rinse to be used twice a day for a two-week period following your surgery.
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..
Who is a candidate for a root canal?
If your tooth is infected or there's severe damage to the pulp, a root canal will be recommended. An untreated cavity is the most common cause for this infection. The pulp inside the tooth can become inflamed from trauma or extensive restorative work. It can even be affected from a series of fillings being applied in a short period of time. This inflammation usually leads to infection. Pain in the tooth is the most common and obvious symptom.
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.
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.
TOOTH CONTOURING AND RESHAPING
What is tooth contouring and reshaping?
Tooth reshaping, or contouring, is one of few instant treatments now available in cosmetic dentistry. Dental reshaping and contouring is a procedure to correct crooked teeth, chipped teeth, cracked teeth or even overlapping teeth in just one session.
The dental contouring procedure can even be a substitute for braces under certain circumstances. It is also a procedure of subtle changes. A few millimeters of reduction and a few millimeters of tooth-colored laminate can create a beautiful smile when performed by a cosmetic dentist, with no discomfort to you. Tooth reshaping, or dental contouring, is commonly used to alter the length, shape or position of your teeth.
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.

How is tooth contouring and reshaping accomplished?
Preparation for dental contouring and reshaping is a team effort with your cosmetic dentist. Some dentists in cosmetic dentistry even use computer imaging to show you how you will look after the procedure.
Your cosmetic dentist will take x-rays to evaluate the size and location of the pulp of each tooth to ensure that there's enough bone between the teeth to support them.
The cosmetic dentist will mark your teeth with a pencil prior to performing the procedure. This helps the cosmetic dentist in their sculpting process. As your cosmetic dentist sculpts the tooth, imperfections are artfully eliminating or minimized. A sanding drill or laser may be used to remove small amounts of surface enamel gradually. Abrasive strips are then moved back and forth between your teeth to shape the actual sides of your teeth. Then the teeth are smoothed and polished. Usually anesthetic is not needed. Teeth contouring and reshaping usually takes one to three visits.
Contouring teeth may also help correct small problems with bite. It is common for bonding to be combined with tooth reshaping to achieve a beautiful 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.
Overview of dentures
Dentures are removable replacements for missing teeth typically made out of an acrylic resin which may at times incorporate porcelain or metal for additional structural support. There are two main types of dentures, complete and partial. Both Complete dentures and partial dentures are finely crafted and custom-fitted to the patient. 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.
How are dentures accomplished?
It is somewhat common to require for some teeth to be extracted, and surgery in some cases is necessary to improve the bony ridges that stabilize your dentures.
The procedure begins with a wax bite impression of your mouth that will give your dentist exacting measurements. A try-on appointment will fine tunes color, shape, and custom-fit.
After your final dentures are fabricated, they will be placed and informed of their required care.
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.
How much do dentures cost?
Costs will vary depending on where you live and your needs. Prosthodontists' prices are typically between $500 to $2,500 per upper or lower arch. Cosmetic Dentist fees are usually $300 to $1,200 per arch. This is a procedure for which you should definitely research your dental insurance coverage. Much of the cost is often covered.
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.
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.
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.
Overview of Dental Implants
Implants are surgically placed in your jaw bone while under anesthesia. It is a very time consuming procedure when having many implants placed. As this procedure is surgical, it is very important to research and find a well credited cosmetic dentist that you are comfortable with. For some people there are varying degrees discomfort or pain, which subsides in a couple of days. As with similar types of surgery, bruising and minor swelling might also develop shortly after the procedure.
How are Dental Implants Attached in Your Mouth?
The implant procedure is a surgical placement of the implant or implants in your jaw bone which requires a three to six month healing period before the implant restoration to replace the missing tooth or teeth. During this healing time, the bone grows in and around the titanium implant creating a very strong support. Dental implants can be rejected. Usually they are replaced with another implant of a slightly larger size. The rejection or "failure" rate is minimal, only 1 to 2% of all implant procedures. You must go without wearing your dentures for one day to two weeks after an implant placement. After the implant has "taken" and you have sufficiently healed, a very natural crown is placed on the implant.
When missing one tooth, your cosmetic dentist may use a Flipper to fill the space. A Flipper is a false tooth to temporarily take the place of a missing tooth before the permanent crown is placed on the implant. 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 to be placed on your implant(s).
If you're missing one tooth or all of your teeth, implants may well be for you. So long as you have enough bone in the area of the missing tooth to facilitate the anchorage of the implants, this procedure can yield terrific results. If you don't have enough bone for this purpose, a bone graft may be necessary. A procedure of building up the bone is known as Bone Grafting. Bone grafting is common with dental implants. The bone that is used is one of three types. The preferred bone to use is taken from other areas of your mouth or collected in a suction device as the drilling of the sites for dental implants occurs. Sometimes bone is taken from areas such as a hip (this requires an orthopedic surgeon and an operating room). The third source for needed bone is a synthetic type. This is the least preferred type of bone to be used for this procedure.
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.
Pros and Cons of Dental Implants
As our life span increases, a permanent dental replacement like implants is increasingly important as we get older. While dentures and removable bridges are usually loose and unstable, implants provide you with dental replacements that are both natural looking and very functional. Implants look much better, and feel better, than traditional removable bridges, and offer the same force for biting as bridges that are fixed in place. Implants will last your lifetime.
Implants are a major investment and not without risk. The extensive use of implants can cost tens of thousands of dollars to achieve a great result. It is also a very time consuming procedure when having many implants placed. As this procedure is surgery, it is very important to research and find a well credited cosmetic dentist that you are comfortable with. For some people there are varying degrees discomfort or pain, which subsides in a couple of days. As with similar types of surgery, bruising and minor swelling might also develop shortly after the procedure. The crown (false tooth placed on top) will need to be replaced in ten to fifteen years.
How long does tooth bonding last?
While the traditional silver fillings last about seven years, these composites should last about seven to eleven years.
How is Tooth Bonding Accomplished?
A very mild etching solution is applied to your teeth to create very small crevices in the tooth's enamel structure. These small crevices provide a slightly rough surface permitting a durable resin to bond materials to your teeth. The resin is then placed on your tooth and high-intensity light cures the resins onto your tooth's surface - with each individual layer of resin hardening in just minutes. When the last coat has been applied to your tooth, the bonded material is then sculpted to fit your tooth and finely polished.
The resin comes in many shades so that we can match it to your natural teeth. Due to the layers involved, this procedure will take slightly longer than traditional silver fillings because multiple layers of the bonding material are applied. Typically bonding takes an hour to two hours depending on your particular case.
Types of Tooth Bonding Procedures
There are two types of bonding. What type is indicated in your situation depends upon whether you have a small area or a larger area that requires correction.
For small corrections
These are one appointment fillings which are color-matched to the tooth and are bonded to the surface for added strength. These are most appropriate for small fillings and front fillings as they may not be as durable for large fillings.
For larger corrections
Dental lab-created tooth-colored fillings require two appointments and involve making a mold of your teeth and placing a temporary filling. A dental laboratory then creates a very durable filling to custom-fit the mold made from your teeth. These fillings are typically made of porcelain. The custom-fit filling is then bonded to your tooth on your return visit. This type is even more natural looking, more durable and more stain resistant.
Who is a candidate for tooth bonding?
If you have close, small gaps between your front teeth, or if you have chipped or cracked teeth, you may be a candidate for bonding. Bonding is also used for patients who have discolored teeth, uneven teeth, gum recession or tooth decay. Bonding material is porous, so smokers will find that their bonding will yellow. If you think you are a candidate for bonding, discuss it with your dentist.
How much does tooth bonding cost?
As with all procedures, prices vary depending on your location. The cost of dental bonding will also vary with the extent of the bonding process you need. Many dental insurance plans cover most of the cost of the bonding, particularly when it is done for structural reasons.
The average cost of cosmetic dental bonding ranges from $300 to $600 per tooth.
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.
What are 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.
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.
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.
