Successful treatment of a gum abscess focuses on the reduction and elimination of the source of infection. This begins with draining the abscess, which usually relieves pain and removes much of the infection. You may be prescribed antibiotics.The periodontal abscess will not be cured unless the cause is eliminated. A Periodontist will prescribe a range of treatment from deep scaling to root planning and gum surgery to treat the gum disease. If the abscess has also affected the pulp, then the tooth will also need root canal treatment as well.
