Most tooth infections and dental emergencies are best evaluated by a dentist or endodontist because the source of the problem is often within the tooth itself.
However, you should seek immediate medical attention at an emergency room if you have difficulty breathing or swallowing, rapidly spreading facial swelling, uncontrolled bleeding, or symptoms affecting your overall health.
For most dental emergencies, an endodontist can diagnose the source of the problem and provide treatment focused on saving the tooth whenever possible.
