Gingivitis, mild periodontal disease, moderate periodontal disease, and severe periodontal disease are the four phases of periodontal disease. Gingivitis is the only stage of periodontal disease that may be reversed since it has not yet attacked the bones. Treatments include brushing and flossing daily, cleaning your tongue, using water picks to remove bacteria from between your teeth, and receiving professional dental care. To treat gingivitis, see a dentist right away if you have any signs of infection (for example, if you feel pain when chewing) or if your gums are red or swollen. The best course of action for preventing gingivitis is to practice good oral hygiene - this includes brushing and flossing daily and seeing your dentist twice a year for checkups. To treat mild periodontal disease, see your dentist every six months for examinations, training on proper brushing techniques, and guidance on how to use interdental brushes or gum massage tools at home. If problems develop during these visits, they can be treated right then and there. In some cases, antibiotics may be prescribed by your doctor to fight bacterial infections associated with periodontal disease. Moderate periodontal disease involves deep pockets forming between your teeth where bacteria can hide. These areas need to be cleaned regularly by a dentist so treatment can begin before further damage occurs.
