Cosmetic Dentistry » White Fillings   If the decay is not too serious, our cosmetic dentist will remove all the decay and restore the tooth with a white (tooth coloured) filling. We can safely replace silver amalgam fillings with white tooth coloured fillings.   Dental decay happens when the enamel and dentine of a tooth become softened by acid attack, producing a cavity (hole).
