are performed to remove decay and restore the affected tooth structure to its normal shape and function. It is called a filling because new material fills the hole that decay has created. If you have a tooth that requires a filling, Dr. Rowntree will remove the decay, clean the affected area and fill the cleaned preparation with a filling material. Teeth can be filled with bonded tooth colored composite resin or amalgam. If caught early enough, cavities can be treated easily and painlessly. If not treated , decay can ultimately lead to root canal treatment or extraction.
