What is
tooth bonding?
Bonding is a term used to describe a number of procedures that involve applying a tooth colored resin, called 'composite' to the tooth. It also includes 'bonding' a porcelain veneer to the teeth. Bonding is often completed in one visit and may not require the use of anesthesia. The process involves preparing the tooth surface with an etching solution that allows the composite resins to adhere. To match the color of your teeth, various color resins are blended so the bonded tooth will look natural. The resin is applied, contoured into the proper shape and hardened using a special light. It is smoothed and polished to appear natural.
How long does it take?
Usually one visit. More visits may be required depending on how many teeth are involved. Porcelain veneers take two appointments.
What is bonding used for?
Bonding can be used for cosmetic purposes to repair chips or cracks, lighten the color or transform gaps into an attractive, natural looking smile. Composite resins are also used to protect exposed roots which results from gum recession. Exposed dentin, due to recession or abrasion, is more susceptible to decay. Composite resins are applied to the tooth roots to restore areas of decay. They also help prevent sensitivity to temperature changes which can occur when roots are exposed.
Who may benefit from bonding?
Almost everyone. However, there are some cases where treatment may not be effective. Dr. Costigane must determine if you are a good candidate for bonding through a thorough oral examination and diagnosis.
Composite resins may be used to fill cavities. Composite resins are tooth colored so as too match the color of your natural tooth.
How does it work?
Instead of silver or amalgam, the prepared tooth is filled with the composite. The decay and old filling must be removed first. Normally, the tooth is numbed to make the process as painless as possible. A special light applied to the white filling hardens it.
What should I be made aware of?
Bonding material is not as strong as a natural tooth. It can chip or stain. It may need to be replaced periodically. Avoiding items that stain teeth such as coffee, tea, soda and tobacco will increase the cosmetic life of your bonding. Chewing ice, pop corn kernels and hard candies can also damage the bonding. Some teeth experience sensitivity after white fillings that normally goes away with time. Composite cannot be used to restore a large cavity or badly broken teeth. These teeth require crowns to properly restore. Ask Dr. Costigane what is the best for you.
