ARESTIN® is a locally administered antibiotic treatment for gum disease. It's a powder composed of 100,000 tiny microspheres that release antibiotics over time. In a single visit, periodontal patients can receive ARESTIN® to the pocket between the gum and tooth. It's a painless procedure, and ARESTIN® with scaling and root planning (SRP) can make your gum disease treatment more effective by killing bacteria left behind after SRP. Best of all, ARESTIN® keeps working long after you leave the dental chair.
