Periodontal surgery in a Biological Dental practice is indicated as a limited therapy of last resort if areas do not respond to non-surgical treatment. Systemic health problems (e.g., diabetes) can cause a deterioration of nerves and blood vessels and can dramatically affect host immuno-competency and resistance to periodontal infection. When local etiological factors and diet patterns cannot explain an impaired or exaggerated soft tissue response to common oral microorganisms, then a medical evaluation may be recommended. When surgery is performed in limited areas, it will be to determine what is preventing healing.
