A composite resin filling is a tooth colored quartz-like material, a clear alternative to traditional mercury/amalgam fillings.
To repair a tooth with a resin filling, first a the decay is removed and the tooth cleaned. Then, tooth colored material is layered into the tooth. Each layer is hardened or cured with highly intense LED light. The final surface is shaped and polished to match the tooth. The final restoration matches surrounding tooth structure.
Resin fillings are great when there is decay on a portion of any tooth, a desire to replace old mercury (silver) fillings, or a desire to maintain a white, beautiful smile.
Resin fillings have many advantages. They are tooth colored and environmentally non-toxic because they use no mercury. They are very strong—because they bond directly to the surface of the tooth. Bonding the filling in place allows the dentist to be very conservative in the preparation without needlessly removing healthy tooth structure.
