BONDING / WHITE FILLINGS A bonding is a composite resin which is tooth colored and is used as an alternative to amalgams (silver-mercury fillings) and veneers.  This is an excellent cosmetic option for those patients who do not want the look of silver in their mouths and do not want the expense of veneers.  Bondings can be used on teeth that are decayed, cracked, or stained. Procedure The bonding procedure is usually completed in one visit.
