It is surgical excision of the gum over the crown of the lower wisdom teeth. It is done most often in partially erupted wisdom teeth. In partially erupted wisdom teeth, the tooth has erupted partially and the gum in the rear end is traumatized constantly due to being caught in chewing. Inflammation manifested by pain, redness and difficulty in opening the mouth occurs due to the gum being traumatized during chewing and the accumulation of food between the gum and tooth. If the wisdom tooth is located normally and does not need to be extracted, the inflamed mucosa, that covers it, is removed. The procedure for cutting the mucosa is very fast and simple. It is always done with anaesthesia, which makes it absolutely painless. Using a scalpel, fine incisions are made around the crown of the wisdom tooth, and then with a special surgical scissors the inflamed mucosa is removed to the neck of the tooth. In rare cases it is stitched, and if there is an infection – drainage is placed for a faster healing of the wound. Painkillers or physiotherapy can be recommended if needed. Dental check-ups and maintenance of good oral hygiene are required.
