What is a coloured filling?
Historically, silver amalgam was the material most often used to restore decayed portions of your teeth, especially back teeth. Silver fillings can really darken a smile, and over time amalgam can cause damage to your tooth. Amalgam fillings absorb moisture and expand and contract with heat and cold. As these fillings age these changes can fracture your tooth; we’ll then need to place a porcelain crown on your tooth to save it. Silver fillings can also undergo metal fatigue, which leads to corrosion and leaking over time. This destroys the protective seal of the filling and allows new decay to develop underneath it. This leakage can give a gray appearance to the entire tooth.
At Normanview Dental, we’ve made a commitment to optimal oral health by only providing white fillings in all our restorations. White fillings are made of a tooth-coloured plastic mixture often called composite resin. These fillings are glued or bonded into place, meaning they add strength to the tooth rather than weaken it over time.
