The term "bonding" describes a dental procedure that is used for various purposes.
Tooth-colored composite resins are applied to teeth for cosmetic reasons, to repair cracked and chipped teeth, protect exposed tooth roots against decay, or restore decayed teeth.
What are some of the benefits?
For cosmetic purposes, bonding can dramatically improve your smile by closing gaps, masking stains caused by coffee, tea, tobacco, or medications, or repairing cracks or chips resulting from accidents.
These tooth-colored composites are well suited for protecting exposed tooth roots caused by gum recession. Tooth roots are covered by dentin that is more susceptible to decay. Bonding helps prevent decay in this area as well as eliminate sensitivity to hot and cold resulting from tooth root exposure.
Since composite materials can match the color of your own teeth, bonding is preferred for filling cavities in the front teeth or wherever else they may be visible.
Bonding does not last as long as porcelain veneers, but it also is not as costly.
What's Involved in the Bonding Procedure?
Usually the process is completed during one visit and sometimes doesn't require drilling or anesthesia. First, your tooth is prepared with an etching solution to help the bonding materials adhere. Next, the resin is applied and contoured to the proper shape, then cured with either a special light or chemical treatment. The tooth is then polished for a natural-looking appearance.
