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.
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.
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.
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.
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..
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.
Dental Root Canals for Your Teeth
Many of us have heard the comparisons of painful things to the root canal procedure. It's not that bad. There are tiny canals within your tooth that may become infected. This leads to the pulp inside your tooth also becoming diseased. Either your dentist or an endodontist to remove any infection performs the root canal procedure. The canals are then filled and the tooth receives either a filling or a crown. Crowns are more common in most cases as they add strength to the tooth itself. The procedure itself takes one to two visits.
What are Root Canals?
There are tiny canals within your tooth that may become infected. This leads to the pulp inside your tooth also becoming infected as well. Either your dentist or an endodontist to remove any infection performs the root canal procedure. The canals are cleaned and then filled and the tooth receives either a filling or a crown.
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.
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.
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.

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.
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.
How are Dental Caps Attached to your Tooth?
A cosmetic dentist will make an impression (mold) of your tooth and a dental laboratory will create the needed custom cap. You will typically leave the office with a temporary cap to wear while the permanent cap is being made - this takes about fourteen days. The permanent cap 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 the permanent cap is actually placed. To stabilize your tooth, a filling must first be put in place prior to placing a cap to counter any loss of your original tooth structure.
It is important to discuss with your cosmetic dentist that the cement color used for your permanent cap will be the same as used for the temporary cap (try in paste). The color of the cement does affect the overall color of a porcelain cap, so this needs to be discussed well before your temporary cap is placed.
In some cases your cosmetic dentist may choose to use a Flipper instead of a temporary cap. 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 cap.
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.
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.
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.
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.
What is a dental bridge?
A dental bridge is a false tooth, known as a pontic, which is fused between two porcelain crowns to fill in the area left by a missing tooth. The 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.
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. Bridges can reduce your risk of gum disease, help correct some bite issues and even improve your speech. Bridges require your commitment to serious oral hygiene, but will last as many ten years or more.
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.
Overview of dental bridge procedure
If you a space from a missing tooth, a bridge will be custom made to fill in the space with a false tooth. The false tooth is attached by the bridge to the two other teeth around the space - bridging them together.
How is dental bridge accomplished?
Your cosmetic dentist will prepare your teeth on either side of the space for the false tooth. You will be given a mild anesthetic to numb the area, and the cosmetic dentist will remove the an area of each abutment (teeth on either side of the space) to accommodate for the thickness of the crown. When these teeth already have fillings, part of the filling may be left in place to help as a foundation for the crown.
The dentist will then make an impression, which will serve as the model from which the bridge, false tooth and crowns will be made by a dental laboratory. A temporary bridge will be placed for you to wear while your bridge is being made until your next visit. This temporary bridge will serve to protect your teeth and gums.
Your cosmetic dentist may have you use a Flipper appliance. A Flipper is a false tooth to temporarily take the place of a missing tooth before the permanent bridge 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 bridge.
On your second appointment, the temporary bridge will be removed. Your new permanent bridge will be fitted and checked and adjusted for any bite discrepancies. Your new bridge will then be cemented to your teeth.
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.

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.
