Your dentist will conduct a complete oral examination to determine the location and cause of the toothache, looking for signs of swelling, redness and obvious tooth damage. He or she may also take X-rays looking for evidence of tooth decay between teeth, a cracked or impacted tooth or a disorder of the underlying bone – problems that the dentist may not be able to find through a routine exam.

Your dentist also may prescribe pain medication or antibiotics to speed the healing of your toothache. If, by the time you see your dentist, your tooth has become infected, then treatment could require removal of the tooth or a root canal procedure, which involves removing the damaged nerve tissue from the middle of a tooth.
