Cavities result from acids in your mouth breaking down the enamel of the teeth. This allows for bacteria to get into the secondary layer called the dentin which causes a cavity to form. To treat a cavity the dentist removes the infected parts of the tooth.
A filling is used to fill the tooth and to restore a functional bite. A filling can also be used to repair a chipped of cracked tooth that result from weakening teeth or misuse (biting on hard objects or being hit in the mouth)
Fillings can be made out of gold, sliver amalgam, porcelain, or a glass composite resin filling.
The location and size of decay, as well as cost of the material, help our doctors determine the type of filling you need.
