Arestin® is an effective antibiotic treatment of chronic periodontitis, an inflamation of the gums. Arestin® comes in powder form and contains “Micospheres”, tiny beadlike particles that are smaller than a grain of sand and are not visible to the eye. The Microspheres are filled with the antibiotic minocycline, and they release the drug into the infected periodontal pocket, killing bacteria that live there for up to 21 days. Dr. Yankie and her hygienists are certified and trained to administer Arestin® to maximize effective periodontal treatment. For more information, please visit
