It is a simple surgery of the gum around your tooth. It is mainly done when the level of your gum has gone down from its regular position due to moderate or severe infection. It is done under anaesthesia which makes it completely painless.
Your dentist will require approximately an hour for the procedure and you can go home within a few hours after the surgery. The dentist may put a pack near the area of surgery and he/she may advise you to have semisolid, bland foods for a few days.
You may be asked to take medicines for a week. After a week your dentist will call you for a follow-up to assess the healing.
