As of 2015, the average cost for full mouth periodontal treatment, which can include pocket depth reduction surgery, is $4000-$6000, but can cost up to $10,000 if gum damage is severe, according to CostHelper. Treatment and surgery for periodontitis is sometimes necessary for people who suffer from serious gum disease.
Periodontitis is a condition in which the tissue around a tooth becomes inflamed, usually due to gingivitis, explains the Consumer Guide to Dentistry. If not treated, teeth can be lost, and the connective tissue and bone can be destroyed. Signs of gum disease are bad breath, bleeding gums, and sensitive or swollen gums.
Because periodontal surgery is not considered a cosmetic procedure, dental insurance should cover some or most of the cost, depending on the type of treatment a dentist recommends, according to CostHelper.
