What is periodontal disease?

Periodontal (gum) disease is caused by bacteria in plaque. If allowed to stay on the teeth, plaque can cause your gums to become red and swollen. This is called gingivitis.

In some cases, the disease will progress to a more severe form of gum disease known as periodontitis. This is where gum next to the plaque peels away from the tooth, forming a ‘pocket’. The bone beneath this pocket is eaten away.

This bone supports your teeth, so this destructive process can result in loosening of the teeth and eventually even their loss.
