What is flap surgery , weather it is dental emergency .?

it is where the dentist or periodontist cuts the gum and flaps is away from the teeth so that the root of the teeth can be accessed for complete cleaning of the root. The gum is then replaced and sutured into position so that healing can take place. Often this is done to reduce deep pockets. It depends on how severe your periodontal disease is as to whether or not it would be considered an emergency - probably doubtful as perio disease is a chronic condition rather than an acute one.
