Dentists use white fillings to fill a cavity in your decayed or broken tooth before capping or bridging becomes necessary. At first, our dentist would extract the damaged part of the tooth and then ‘fill’ in the missing part of your tooth with a white filling. White Fillings enjoy certain advantages over other fillings types ranging from aesthetics to functionality. Bonding is easier as they are made of materials that are more amiable to the structure and tissue of teeth. White fillings are also known as composite fillings.
