Wisdom teeth grow in almost all adults, though some people may have fewer or more of them. They are vestigial molars that we no longer use. In cases where the wisdom teeth grow with no problems, it is not necessary to eliminate it. However, there are many instances where growth cause pain and discomfort and wisdom tooth extraction is the only solution.
Unnecessary teeth extraction is ill-advised and doctors warn that people who get them removed despite having no pain and discomfort before are not guaranteed protection against future problems. There is a belief that the initial extraction can help prevent tooth crowding. This is false and the elimination of unnecessary teeth can leave one susceptible to infections and numbness if the nerve is damaged.
If the impacted wisdom teeth have difficulty growing straight up, the dentist will recommend that they need to be extracted. Any prior infection will first have to clear up before surgery is performed. Patients will be given either a local anaesthetic or general anaesthesia.
The second option is recommended if two or more teeth are to be extracted. Once the patient is under anaesthesia, the gum tissue is opened and any bone covering the tooth is removed. The teeth are then taken out whole or broken into pieces for easy removal.
