Advanced gum disease is result of disease causing bacteria present on root surfaces and bone underlying gums. Flap surgery involves raising your gum tissue to gain access to underlying root surfaces and bone to remove these disease causing bacteria. Simultaneously, bone grafting can be done to encourage natural ability of body to regenerate bone lost due to disease.
With a combination of daily oral hygiene and professional maintenance care, you'll increase the chances of keeping your natural teeth – and decrease the chances of other health problems associated with periodontal disease.
