Bonding

What It Does
The term bonding is used to describe procedures where tooth-colored dental resins and composites are used. Direct bonding techniques can be used to change the shape and color of teeth as well as to close unattractive spaces. It can also be used to repair chipped or broken teeth or even to cover up unsightly stains. Unlike crowns or caps, direct bonding requires only a minimal amount of tooth reduction thus making it a very conservative procedure.

How It Works
After slight preparation, the tooth is etched with a weak phosphoric acid solution to create a more porous and rougher surface for increased bonding strength. Next, a composite (plastic) resin is placed on the tooth and shaped, contoured and hardened with a special curing light. It is then further shaped and highly polished creating a very natural appearance. The procedure usually requires only one visit and is not painful.

How Long It Lasts
The bonded composite has an average life of four to eight years, and often lasts longer depending on how and where in the mouth it is applied and how it is maintained. The area can be touched up and even re-bonded over time as necessary.
