| Reasons for Extraction |  Some people have extra teeth that block other teeth from coming in.
 People exposing orthodontic work may need teeth extracted to make space for the teeth that are being moved into place.
People receiving radiation to the head and neck may need to have teeth in the field of radiation extracted.
People getting chemotherapy may be at high risk of developing infected teeth since chemotherapy depletes the immune system, in such a way increasing the risk of infection. Therefore, these teeth may need to be extracted.
People receiving an organ transplant may need some teeth extracted if the teeth are at risk of becoming sources of infection after the transplant, when immunosuppressive medicines are given.
Wisdom teeth, also known as third molars, often are extracted either before or after they come in. As a rule, they come in for the duration of your late teen years or early twenties. Impacted teeth stumble in the jaw and often have to be removed if they are decayed or are the cause of pain.
A wisdom tooth that has appeared partly may be obstructed by other teeth or may not have enough space to come in totally. This can annoy the gum, causing pain and swelling, which requires the tooth to be removed.
