    inflammation and loss of periodontium that is characterized by rapid attachment loss and bone destruction in the presence of little local factors such as dental plaque and dental calculus. this highly destructive form of periodontitis often occurs in young people and was called early-onset periodontitis, but this disease also appears in old people.

Patient Education


Gum 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.
