Dentist with specialist training carry out extractions and advanced surgical procedures such as removal of impacted wisdom teeth under local anesthetic. Wisdom teeth are the third and final set of molars that most people get in their late teens or early twenties. If they are misaligned and causing problems they may require removal.

Badly decayed or neglected teeth may need extraction. Infection from a necrosed tooth may spread to the root apex and periapical bone causing an inflammation, as a result of which the tissue surrounding the bone gets swollen, the tooth gets detached and may react painfully to touch. If the inflammation is chronic an abscess can be seen around the root apex in the x-ray. If the tooth is beyond restoration then an extraction is necessary.
