Information for Patients


Gum Disease

Also called: Periodontal disease

If you have gum disease, you're not alone. Many U.S. adults currently have some form of the disease. It ranges from simple gum inflammation, called gingivitis, to serious damage to the tissue and bone supporting the teeth. In the worst cases, you can lose teeth.

In gingivitis, the gums become red and swollen. They can bleed easily. Gingivitis is a mild form of gum disease. You can usually reverse it with daily brushing and flossing and regular cleanings by a dentist or dental hygienist. Untreated gingivitis can lead to periodontitis. If you have periodontitis, the gums pull away from the teeth and form pockets that become infected. If not treated, the bones, gums and connective tissue that support the teeth are destroyed.

Tooth Disorders

Your teeth are made of a hard, bonelike material. Inside the tooth are nerves and blood vessels. You need your teeth for many activities you may take for granted. These include eating, speaking and even smiling. But tooth disorders are nothing to smile about. They include problems such as cavities (also known as tooth decay), infections, and injuries.

The most familiar symptom of a tooth problem is a toothache. Others include worn-down or loose teeth. It's important that you see a dentist if you have any problems with your teeth. Fortunately, you can prevent many tooth disorders by taking care of your teeth and keeping them clean.
