A simple extraction is the removal of a visible baby tooth from the mouth. A simple extraction is performed by a dentist using a "elevator," which loosens the tooth, and then forceps. A local anesthetic is usually all that is required for these extractions. The patient may experience some discomfort during recovery, but this is normal. The dentist will take care not to hurt any nearby nerves when removing teeth. If any nerves are damaged during the process they will not function properly, which could lead to pain, sensitivity, or numbness in the area near the injured nerve. Teeth can also be removed if they cause harm to other parts of the body. For example, a dentist may remove a severely decayed tooth if it is causing pain or infection in the jawbone below. Such problems are more likely to occur with older teeth and those who suffer from diabetes or cancer treatments that damage the bone tissue. Finally, teeth may be extracted if they are trapped between the bones of the face. In this case, surgery is required to free the tooth without injuring the surrounding tissue. Extractions can be stressful for children as well as adults. Children may worry about being unable to eat anything solid for several days following an extraction. They may also feel limited in their ability to speak or smile because of the bandages placed over the face.
