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.
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.
How much does laser teeth whitening cost?
Costs can vary depending upon the area of the country you live in and the type of whitening treatment you undergo. Laser teeth whitening is typically over $1000. for the complete procedure.
Generally speaking, the price of teeth whitening increases with the number of in-office treatments required by the patient. Dental insurance does not typically cover the cost of the teeth whitening procedure.
Pros and Cons of Teeth Whitening
People typically have their teeth whitened to improve their appearance. Whiter teeth are associated with beauty and a healthier lifestyle. When people have a brighter smile, they tend to smile more often and are less self-conscious.
In addition, a whiter smile tends to minimize the appearance of facial wrinkles, giving way to a more youthful and energetic appearance.
Finally, a whiter smile gives people to whom you are speaking a place to focus on and gives you a friendlier appearance.
Although bleaching is very effective, there can be short term disadvantages, such as sore gums or teeth from the bleach. This disappears when bleach use is discontinued. Some individuals are more chemically sensitive. If you are one of them, inform your cosmetic dentist so that you can be tested for sensitivity to the solution.
Research indicates that bleaching is completely effective in more than 78% of people. In cases of serious teeth discoloration, bleaching may not be the best choice. Veneers or crowns may be the superior choice. Bleaching is usually the first solution to try due to its lower cost.
Some people experience discomfort from wearing the mouth tray. This typically goes away in short order, but if you suspect that there is a problem with the fit of your mouth tray, call your dentist's office. They can often make small adjustments that will minimize or eliminate the problem.
Pros and Cons of Cosmetic Gum Surgery
Healing is usually quick and your more youthful and beautiful smile is obvious early on. It has been reported that cosmetic gum surgery additionally improves the health of your gums. The procedure to correct receding gums may even reduce your tooth sensitivity to cold or hot foods or beverages while protecting your roots from decay and lessening further gum shrinkage.
Cosmetic gum surgery is of course, surgery. Surgery is often performed in segments under a local anesthetic - unless your entire mouth is undergoing this procedure at once, then a general anesthesia is typically used.
How are Dental Root Canals Performed?
Depending on the number of teeth and severity affected, root canals usually require one to two visits not including any follow-up visits. Your dentist or endodontist will numb the area around the affected tooth, or may offer you the option of mild sedation. The tooth is then drilled to the pulp area either through the top or the back of the tooth. The actual root canals are measured after some of the pulp has been removed. This is done so that the dentist can clean the entire canal, and so that enough of the filling material will be used to completely fill the canal. The actual measuring is done with either x-rays or electronic imaging devices.
All of the diseased pulp in the tooth is removed, and the canal is cleaned out thoroughly with an antiseptic solution. This solution will clean all of the canals within the tooth. The canals are then filled with gutta percha, a flexible plastic material. A temporary filling is then put on top of that. A crown or permanent filling will be done after there has been no sign of infection. Crowns are most common since the root canal procedure weakens the tooth. The crown is usually placed as soon as possible, within a month or less.
Expect two to three days of soreness after the procedure, or longer if the infection in the root canal was severe.
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.
How much do dental root canals cost?
Expect the cost of a root canal treatment to be about $400. to $600. per front tooth and about $500. to $800. for a molar. The difference is because front teeth usually have only one root canal and molars usually have three or more. The costs for a crown or permanent filling are additional. Costs for a second root canal, hopefully not needed, on the same tooth are slightly higher.
Who is a candidate for Dental Veneers?
Veneers, porcelain or plastic, are placed over the front teeth to change color shape of the teeth. Veneers are ideal for teeth that are too small, too big, or have uneven surfaces. It is very common for people to have imperfect teeth, either oddly shaped teeth, chipped teeth, crooked teeth,teeth with small holes in them, or an inappropriate sized tooth or teeth that have an odd appearance. Veneers solve such irregularities and create a durable and pleasing smile.
Types of Tooth Veneer Procedures:
There are two tooth veneers 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 tooth veneers procedure for you.
Composite Veneer Procedure:
Composite (direct) veneers are usually performed in a single visit to your cosmetic dentist. The procedure is an application of a bond and enamel directly to the tooth's surface.
Porcelain Veneer Procedure:
Porcelain (indirect) veneers are a very thin porcelain material. Usually porcelain veneers require two visits and also require a dental laboratory to create the final tooth restoration piece.
How much do tooth veneers cost?
Porcelain Veneers typically cost between $900 - $2,500. per tooth and require two or more visits one to two weeks apart. Veneers made of porcelain provide a greater longevity than plastic, typically ten years to fifteen years or more.
Composite Veneers cost significantly less, around $250 per tooth or more, but only last from five to seven years typically.
Generally speaking, the price of tooth veneers and whitening increases with the number of in-office treatments required by the patient. Dental insurance does not typically cover the cost of the tooth veneers procedure.
Overview of tooth contouring and reshaping
Dental reshaping and contouring is a procedure to correct crooked teeth, chipped teeth, cracked teeth or even overlapping teeth in just one session. This procedure is even a substitute for braces under certain circumstances. This is also a procedure of subtle changes. A few millimeters of reduction and a few millimeters of tooth-colored 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.
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.
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.
Who is a candidate for dentures?
If you've lost, or are losing, all of your teeth a Complete Denture is something to discuss with your cosmetic dentist. If some of your teeth remain and are healthy, a partial denture may be your way to a great smile.
This procedure should be thoroughly discussed with your dentist as there are several personal and medical factors to take into consideration. You may instead be a candidate for dental bridges and dental implants as optional procedures.
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.
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.
Types of Tooth Caps
There are generally three types of caps - those made of gold, ceramic caps and ceramic-veneered gold caps. Gold and metal-ceramic caps are extremely durable and are normally used in molars, where the forces from chewing and grinding are most prevalent. Ceramic caps are used primarily for front teeth, since they can best resemble the natural tooth color and are more pleasing to the eye.
Types of Porcelain used with Dental Caps
There are basically two types of porcelain you're likely to hear and read about most when researching dental caps and crowns- 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 of the dental cap or crown 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 of the cap or crown. The stains and opaques are applied only to the surface of the porcelain to give a natural look for your new smile.
Resin and Porcelain Caps
The new reinforced resin or bonded all-porcelain type of cap has the nicest appearance. This cap can be made from pure ceramic or a new reinforced composite resin. It 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 the parts of your tooth that are in need. This procedure is metal-free.
Caps Made of Gold
Gold caps are used when appearance is not a priority to you. The gold is extremely workable, making gold caps a more precise fit than any other type. While there exists a slight possibility of chipping with porcelain caps, gold caps provide no such possibility.
Porcelain and Metal Caps
For a very natural appearance, porcelain fused to metal caps are the answer for you. However, they have a metal substructure and require an opaque below the porcelain, which can make the translucency of natural teeth difficult to match. Sometimes a darker line will be visible at the edge of the cap, near to your gum when your gum recedes with age.
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.
What is tooth bonding?
Bonding is a composite resin filling placed in the back teeth as well as the front teeth. Composites are the solution for restoring decayed teeth, making cosmetic improvements and even changing the color of your teeth or the reshaping of teeth. Bonding will lighten any stains you may have, close up minor gaps and can be used to correct crooked teeth. 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 and sculpt, color and shape it to provide a pleasing result. A high-intensity light then hardens the plastic, and the surface is finely polished.
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.
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.
Types of Dental Bridge Procedures
There are three types of dental bridges:
Traditional Fixed Bridge
A dental bridge is a false tooth, known as a potic, which is fused between two porcelain crowns to fill in the area left by a missing tooth. There two crowns holding it in place that are attached onto your teeth on each side of the false tooth. This is known as a fixed bridge. This procedure is used to replace one or more missing teeth. Fixed bridges cannot be taken out of your mouth as you might do with removable partial dentures.
Resin Bonded Bridges
The resin bonded is primarily used for your front teeth. Less expensive, this bridge is best used when the abutment teeth are healthy and don't have large fillings. The false tooth is fused to metal bands that are bonded to the abutment teeth with a resin which is hidden from view. This type of bridge reduces the amount of preparation on the adjacent teeth.
In areas of your mouth that are under less stress, such as your front teeth, a cantilever bridge may be used. Cantilever bridges are used when there are teeth on only one side of the open space. This procedure involves anchoring the false tooth to one side over one or more natural and adjacent teeth.
Pros and Cons of a Dental Bridge
Advantages of dental bridges:
Bridges are natural in appearance, and usually require only two visits to your dentist. If you maintain good oral hygiene, your fixed bridge should last as many as ten years or more.
Disadvantages of having a dental bridge:
It is common for your teeth to be mildly sensitive to extreme temperatures for a few weeks after the treatment. The build up of bacteria formed from food acids on your teeth and gums can become infected if proper oral hygiene is not followed.
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.
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.

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.

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.
