When decay has eaten away at one of your teeth, a hole remains. Dr. Geare needs to fill this hole to prevent further decay. There are basically two types of filling, ‘silver’ fillings and ‘white’ fillings.
Composite Resin (White Fillings)
Composite resin, or white filling, is made of a strong resin that is matched to your surrounding tooth color. In the past, white fillings were used only on front teeth. Now, a stronger structure allows them to be used on back teeth as well. White fillings bond to tooth structure and usually require less removal of healthy tooth structure. Bonded fillings are considered more cosmetic than silver fillings.
It can take longer to fill your cavity with a composite than a silver filling, and can cost up to twice as much as silver fillings.
