This is one of the most common oral surgery procedures. Due to the position of the third molars (wisdom teeth) in many people they do not fully emerge into the mouth but can become impacted against the next molar or against the bone of the jaw.
When problems occur and the decision is taken to surgically remove a third molar, your oral surgeon will have very carefully assessed the benefits and deficits of the treatment and you will be fully informed of these. Because of the proximity of other structures such as nerves, there is a small chance of damage to these during the surgical procedure. One of the most important factors to try and limit the risk of these negative outcomes is for your surgeon to be as clear as possible exactly where your tooth is in relation to these other structures.
