How common is chronic periodontitis?

Chronic periodontitis is the most common form of periodontitis, affecting about 85 percent of the population to a greater or lesser extent. Advanced periodontitis affects less than 5 percent of the population.

The risk of periodontitis increases with age, becoming a cause for concern and awareness in adults over 35 years old. One study found that 86 percent of individuals over 70 years old suffered moderate periodontitis, with more than 25 percent of this demographic suffering from lost teeth.
Most adults have some level of chronic periodontitis (gum disease), but for many the condition is so mild that it doesn't cause significant discomfort. Exactly how many people have chronic periodontitis depends on the definition used for the disease. If chronic periodontitis is defined as the loss of at least 2 millimeters (mm) of the tissues that attach at least one tooth to the jaw bone (known as clinical attachment loss), then 80% of all adults in the United States have chronic periodontitis.
