extraction is the removal of a tooth from its socket in the bone. The
teeth, which have been damaged by decay or fracture, will be repaired
and restored with a filling, crown or other treatment by the dentist.
But sometimes if the damage is too extensive, the teeth cannot be
repaired. Then it is necessary to do the extraction.
Reasons for extraction:
• The extra teeth that block other teeth from coming in.
• People undergoing orthodontic work may need teeth extracted to create room for the teeth that are being moved into place.
• The people, who are having radiation to the head and neck, may need to have teeth in the field of radiation extracted.
• The people who are receiving chemotherapy may need to have the teeth extracted. Because chemotherapy weakens the immune system and the risk of infection increases. So these teeth may need to be extracted.
• The people receiving an organ transplant may need some teeth extracted. Because when immunosuppressive medications are given, there is a risk of becoming sources of infection for the teeth after the transplant.
• Impacted teeth, especially third molars, commonly come during the late teen years or early twenties. These teeth are often extracted either before or after they come in. These teeth get stuck in the jaw and they need to be extracted if they are decayed or cause pain.
