Flossing in between your teeth is essential for avoiding periodontal disease as well as preventing tooth decay. Both are caused by plaque, the sticky substance that forms on and in between the teeth.

A dental implant is a metal device designed to replace missing teeth. The device is usually made out of titanium and is surgically placed into the jaw bone where the tooth is missing.
