Periodontal Therapy is a three-step process. First step is diagnosis. Periodontal disease is diagnosed by your dentist or dental hygienist during a periodontal examination. This type of exam should always be part of your regular dental check-up. Second step is treatment. Periodontal treatment methods depend upon the type and severity of the disease. Your dentist and dental hygienist will evaluate for periodontal disease and recommend the appropriate treatment. The third step is maintenance. It only takes twenty four hours for plaque that is not removed from your teeth to turn into calculus (tartar)! Daily home cleaning helps control plaque and tartar formation, but those hard to reach areas will always need special attention.
