Hi Hisjen84. My dentist had signs in his office and stickers on the surgical lights : "We cater to cowards". Many people (including me at one time) are terrified of dentists. I have had root planing and scaling done a few times in my lifetime. It can be unpleasant. To my knowledge it has no affect on the appearance of your teeth. At least not in my case or others I have known to have the procedure. I am in the USA. Here, if it is too uncomfortable for the patient, the dentist can give local anesthesia to numb the gums. You should not hesitate to ask for it it you feel you need it. If you have deep pockets, you will likely need the numbing. I had the procedure without anesthesia, but I know that may be for everyone. You can expect your gums to be tender for a few days afterward. It is a very good thing you are looking after your oral health. Unless your blood sugar numbers are extremely out of range, you should heal OK.
