Bonding/White Fillings

A bonding is a composite resin that is used as an alternative to amalgam (silver) fillings. This is an excellent cosmetic option for those patients who do not want the look of silver in their mouths. Bondings can be used on teeth that are decayed, cracked, or stained.

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 liquid or gel and a bonding agent is then applied. This will allow the composite resin to be placed in the prepared tooth. The resin is then trimmed and polished, leaving you with a beautifully sculpted, natural-looking restoration.

Bonding Durability
Although composite resins are cosmetically pleasing and easily placed, their durability is not as strong as other types of restorations. These resins typically last from 4-7 years before they begin to chip and wear away. When this happens, the restoration will need to be replaced.

Amalgam (Silver) Fillings

Amalgam, or silver, fillings have been around for more than 150 years. They are strong and durable, but can be cosmetically un-appealing. For this reason we generally place these fillings in areas of the mouth that are not easily seen but need extra strength. They are more economical than the white composite fillings, and can be placed faster. The controversy surrounding these fillings stems from the mercury that is present in small amounts that help to bond the other metals together (silver, tin, copper, zinc). This mercury is in a different chemical form than the elemental mercury found in fish and other unhealthy sources. Any mercury is a concern of course, but decades of research and 150 years of safe use are a testament to the efficacy of these fillings.
