When you get a filling, you want it to match your existing teeth as closely as possible. Composite fillings can do this. They are mercury-free and are made with a combination of glass and quartz filler in a resin matrix. Composite fillings can be used to replace tooth decay, fill gaps, replace older non-matching fillings, or repair uneven tooth surfaces.
Using micro bonding technology, the filling material is bonded to the tooth's surface. The composite material is designed to match the other teeth in your mouth, both in color and translucency. A light curing process is used to harden the composite material. Based on currently available technology, you can expect any composite fillings installed by the Amherst cosmetic dentists at EMA Dental to last about seven years.
