A dental emergency is any dental issue that needs immediate attention. The two most common types of dental emergencies are damage to the teeth and gums, and damage to dental implements like crowns, bridges, implants, and fillings. It should be noted that a dental emergency is different from a medical emergency. If an injury presents life threatening symptoms or affects more than just gum and tooth health, you need to call 911 or head immediately to an emergency room at a local hospital.
