Ever wondered whether you should do anything about those “old metal fillings”?
Overtime, amalgam fillings can weaken teeth. This is because they do not adhere to the tooth surface so when you bite down the force is transmitted onto the remaining tooth structure. This can subsequently result in the formation of a crack in the tooth.
In comparison, white fillings (composite resin) chemically bond to the tooth’s surface. This adhesion means the chewing forces are distributed over a larger surface area and thus reduce the likelihood of crack formation. Not only are composite resin fillings superior in required strength to amalgam filling but they also help to strengthen the weakened tooth. The material comes in a range of shades that can be matched to your natural tooth colour, helping give you that perfect smile. For these reasons, we do not use amalgam at The Smile Company.
