<s>[INST] Hi Doc ,My mom is suffering form pyria(1st ) stage  & doc suggest to have a surgery like flapp surgery or laser surgery so what will be the best and surgery is the only option for pyria ?* she has no pain in teeth * no bleeding * only gums started leaving  teeth please suggest something [/INST] Hello!Welcome to HCM.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 mother's 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. </s>
