Periodontics is the area of dentistry that focuses on gum disease treatment. If caught in the early stages, your dentist can reverse gum disease. To begin, the dentist will scale the teeth to remove plaque and calculus, and plane the roots to smooth them. The doctor may also prescribe antibiotics to clear up any infection or inflammation. Advanced cases may require your dentist to surgically trim the gums, disinfect the tissue, remove the hardened plaque build-up, and re-contour the damaged bone.
