If calculus develops below the gums onto the tooth root, it makes plaque removal more difficult, leaving you at increased risk for periodontal diseases. These toxins also can destroy the supporting tissues around the teeth, including the bone. When this happens, gums separate from the teeth, forming pockets that fill with even more plaque and more infection. As the diseases progress, these pockets deepen, more gum tissue and bone are destroyed, and the teeth eventually become loose. If periodontal diseases are not treated, the teeth may need to be removed.
Periodontal diseases can affect one tooth or many teeth.
For example, your front teeth may not show signs of periodontal diseases while a tooth in the back of your mouth may become loose due to severe disease progression.
