Most dentists remove wisdom teeth in general practice. It can be a normal and routine procedure. In some cases, wisdom teeth can become trapped under the gum in the bone, at difficult angles to physically see. A dental x-ray will confirm this. In these circumstances, extraction can be tricky because actually seeing and gaining access to a small space in the mouth may be impossible. This is circumstance it may be necessary for a specialist to assess the position of the tooth and extract it due to greater experience in dealing with awkward cases. This may involve a small surgical procedure where you may have local anaesthetic with or without the use of sedation. Sometimes it can be kinder to have a general anaesthetic especially removing very difficult teeth or multiple teeth.
