In the past, dentists used fillings made of silver and mercury to repair cavities and tooth decay. Not only are old silver fillings unattractive, there are concerns that these amalgam fillings may cause mercury poisoning. If you are sensitive to metals, are concerned about the mercury content of an amalgam filling, or simply want to preserve your natural beautiful smile, white fillings may be right for you.
White fillings, or composite fillings, are made from a tooth-coloured material that restores the natural appearance of a decayed or previously metal filled tooth cavity. Because white fillings blend perfectly with your tooth enamel and are quite strong, Dr. Valenzano will often recommend them for both front and back teeth.
A white dental filling typically requires only one dental visit, during which the tooth or teeth are prepared and restored with white tooth fillings. An advantage of white tooth fillings, as compared with other dental restorations, is that they need less of the healthy part of a tooth to be removed to hold the filling in position. This is due to the filling’s composite material being capable of bonding to the teeth more tightly.
