Periodontal disease is not curable but it is treatable. You have to schedule regular visits to see your dentist (instead of the avg every 6 mths you would see your dentist every 3 mths) for cleaning and maintenance of your condition and practice good oral hygiene at home. Brushing at least twice a day and flossing once a day. Flossing is especially important for patient with periodontitis. You can also purchase a water pik to use at home that will help aid in your oral hygiene but use warm water otherwise the cold water will cause you pain and sensitivity.
