Gingivitis usually refers to gum inflammation while periodontitis refers to gum disease and the destruction of tissue and/or bone. Initially, with gingivitis, bacteria plaque accumulates on the surface of the tooth, causing the gums to go red and inflamed; teeth may bleed when brushing them.
Evidence indicates that periodontal disease is an autoimmune disorder triggered by infectious organisms and an abnormal immune response to collagen. Periodontal disease is an inflammatory condition affecting both the gums and the deep structures that house the roots of the teeth.eriodontal disease can cause the teeth to loosen and decay. Individuals with periodontal disease may experience bleeding of the gums when brushing, which is often the first sign of a problem. The gums may also appear swollen and recede away from the teeth.
