The aim of pocket reduction surgery is to reduce the depth of the gum pockets and make it more difficult for bacteria to invade the gum tissue. Initially, the gum tissue is pulled back from the teeth and the subgingival area is thoroughly cleansed under local anesthesia. Extensive scraping may be required to fully remove the plaque, debris and tartar from below the gum line. An antimicrobial agent may then be applied to the affected area to kill any remaining bacteria. Pocket reduction surgery is very effective for halting tissue loss and promoting the natural healing of the gums.
