Cracked tooth syndrome , is a common cause for dental pain. Patients experience pain upon chewing or with temperature. The dentist will usually check the tooth by having the patient bite on a bite stick or with air. The pain will go away once the stimulant is gone. The dentist prepare the tooth for a crown to help splint the tooth together and keep it from fracturing. If we catch it early, we normally do not need to perform tooth canal therapy. If you are experiencing dental pain, get into the dentist as soon as possible. The longer you wait, the more chance of irreversible nerve damage in the tooth that would necessitate root canal therapy.
