Healthy gums help to anchor teeth firmly in place. Gums are a nice pink color and do not bleed when brushed.

Gum disease is caused by bacteria which forms around teeth. You know this sticky substance as plaque. Toxins from the bacteria inflame the gums and eventually cause them to 'pull away'. An early stage of gum disease is called gingivitis. This picture shows an advanced case of gingivitis.

As periodontitis sets in, the gums begin to 'pull away' and more of the tooth is exposed. Plaque attaches itself securely to this newly exposed area and hardens into tartar. Pockets form between the teeth and gums which harbour bacteria and worsen the condition.

Eventually so much of the tooth is unprotected that it begins to losen. The bone is irreversibly damaged. It can change they way your teeth fit together (your bite). Eventually your teeth may fall out or have to be pulled out by your dentist.

You can prevent gum disease by taking care of your teeth along with regular dental checkups.

1. Remove plaque before it becomes tartar by brushing well, twice a day.

2. Floss regularily, and don't be afraid to clean 'below' the gumline.

3. Eat healthy foods. Diet can play a big part is preventing gum disease.

4. Visit your dentist regularily. Professional cleaning is a big help when combating gum disease.
