This is used in combination with a periodontal regimen recommened by your dentist to help control active gum disease. It is a time released medication that works for about 10-14 days. It is recommended that we refrain from the use of string floss, water floss or toothpicks and the likes for that period of time to allow the medication to work continously. The sites treated with Arestin will be monitored and checked by your dentist or hygenist.
