Tooth Colored Fillings
Tooth colored fillings are a popular alternative to century old silver amalgam fillings. They are known to be a safer and more effective option to treat cavities or replace old fillings. Studies show that silver amalgam contains about fifty percent mercury, a chemical that has a tendency to be more toxic than cadmium, lead, or arsenic. It is thought that mercury may cause psychological and physical problems in some patients.
Tooth colored fillings are made of composite resin which is bonded together with the tooth’s surface via strong dental adhesive. A curing light is then used to harden the filling, which is afterwards polished to make it look like enamel. There are several occasions when a tooth colored filling can be used. For instance,
- When a cavity needs to be filled
- To enhance cosmetic appearance
- To correct tooth fractures and chips
