A white filling, also known as composite or tooth colored filling, is used to repair a tooth that is affected by decay, cracked or fractured tooth, etc. The affected portion of the tooth is removed, and then filled with a composite filling. The white fillings, along with the silver amalgam fillings, are the most widely used nowadays.
There are many types of filling materials available, each with its own advantages and disadvantages. You and the dentist can discuss the best option for restoring your teeth.
