Sometimes, the gums and bone don't heal after periodontal therapy. This can be due to a multitude of factors, including the patient's systemic health and their home care. Certain conditions like diabetes and heart disease make healing after periodontal therapy a little more difficult. In these instances of insufficient healing, we incorporate antibiotic therapy into the treatment regimen. Antibiotics are gently placed beneath the gum line and allowed to penetrate the gums and bone for a period of 7-10 days. We usually see resolution of inflammation after antibiotic therapy and the patient is placed on a maintenance schedule of regular three-month checkups.
