Welcome to Chat Doctor. Flap surgery removes the infection below the gums. Laser surgery is very comfortable to the patient as well as the doctor. It is done in a blood less field. However, a scalpel flap surgery is preferred because it is friendly to bone. Consider your mothers general health, age and co-operative status and decide on it. She must visit the dentist every 6 months after surgery for a maintenance scaling session.
