What is periodontal disease?
Periodontal disease is an infection that affects the tissues and bone that support teeth.

Healthy gum tissue fits like a cuff around each tooth. When someone has periodontal disease, the gum tissue pulls away from the tooth. As the disease worsens, the tissue and bone that support the tooth are destroyed. Over time, teeth may fall out or need to be removed. Treating periodontal disease in the early stages can help prevent tooth loss.
