|Periodontal diseases are classified according to the severity of the disease. The two major stages of the disease are Gingivitis and Periodontitis.
Periodontitis occurs when toxins, enzymes, and other plaque byproducts destroy the tissues that anchor teeth into the bone. The gum line recedes, winch can expose the tooth’s root. Exposed roots can become susceptible to decay and sensitive to cold and touch.
Usually your dentist can still treat the disease at this point. In the worst cases, a loose tooth may need to be extracted or it may fall out on its own.
