White fillings are used to fill cavities or chips in your teeth caused by decay, grinding or injury. White fillings fill your cavities without using any metal, creating a smile you can be proud of.
There are many different advantages to white fillings over silver metal fillings. White fillings can be colored to match the appearance of the rest of your tooth, they require less natural tooth to be removed in order to be placed, and bond directly to the tooth tissue, therefore strengthening a weakened tooth and sealing the gap between the tooth and the filling. Metal fillings do not bond to the tooth tissue and leave a gap at the margin between the tooth and the metal filling, bacteria can travel back into and cause recurrent decay.
White fillings are created out of a white composite resin that is bonded to the tooth with a special adhesive and a bright curing light, and matches the shade of your natural tooth.
