Dental emergencies can occur when your tooth breaks, cracks, becomes loosened, or is knocked out completely. They can also happen if a filling or other dental work fails, or if you have an acute dental infection.
Dental emergencies can be avoided by taking some simple precautions, such as wearing a mouth guard during sport, and avoiding hard foods that may crack or break your natural teeth or dentures.
If your tooth is knocked out or loosened and pushed out of position you should call your dentist immediately and book an emergency appointment. If you can see your dentist within an hour of the incident, your tooth will have the best chance of surviving the trauma.
