Bonding fillings are called (composite) or “tooth colored” fillings. The procedure involves first removing the decay. Next, a resin is painted on the tooth and acts like a glue. Then a filled resin composite is placed on the tooth and set to a solid using a special light. The composite is finally polished and adjusted to your bite.
These fillings have been used on front teeth for decades. These are now used on molars too, instead of silver (amalgam) mercury fillings. These fillings are safer, better looking, and allow more conservation of tooth structure.
