Bonded White Fillings
A bonded filling is a composite resin that is used as an alternative to amalgams and veneers. This is an excellent cosmetic option for those patients who do not want the look of dark metal 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. The first step is to remove the decayed or unsightly portion of the tooth. The tooth is then etched with a special gel and a bonding agent is then applied. The composite resin filling of the same tooth shade is then bonded to the prepared tooth. The resin is then finished and polished, leaving you with a beautifully sculpted, natural-looking restoration.
Bonding Durability
Although composite resins are cosmetically excellent and easily placed, their durability may not be as long as porcelain. These resins typically last from 5-10 years before they begin to stain and wear away. When this happens, the restoration will need to be replaced.
Why we do not use amalgam
We no longer use amalgam as it is not kind to the teeth; it weakens the teeth, often causing teeth to fracture later. It contains certain metals of doubtful safety, and of course amalgam fillings just do not look nice. On the other hand, not only do bonded white fillings look better, they re-inforce the teeth so that later fracture of the teeth can often be prevented.
