A dental emergency is any situation that involves severe pain, uncontrolled bleeding, trauma to your mouth, or risk of losing a tooth. This includes severe toothaches that don’t respond to over-the-counter pain medication, knocked-out or loosened teeth, broken teeth that expose the nerve, abscesses or facial swelling, and lost fillings or crowns that cause significant pain. If you’re experiencing any of these symptoms, you should seek emergency dental care immediately. Delaying treatment can lead to more serious complications, permanent damage, or the loss of teeth that could otherwise be saved.
