Medical history and physical exam by a doctor or dentist. Laboratory culture of the plaque to identify the bacteria responsible for the infection. Doctor's or dentist's treatment. Surgery to remove infected gum tissue, if other treatment fails. Untreated gingivitis may lead to periodontitis, an advanced stage of gum disease that can lead to bone loss and loosening of teeth.
Treatment is with antibiotics.
Scrub clear, sticky plaque off the teeth daily with a soft toothbrush. Place the brush at the gum line and gently rotate it, pointing bristles toward the gum. Brush one section of teeth at a time. A soft brush is less likely to damage teeth and gums than a hard brush. Floss your teeth at least once a day.
