A knocked-out tooth is always a dental emergency. If possible, try to put it back in its socket. Wash it off first to remove any dirt or debris. Biting down on gauze can be helpful. Just be careful to avoid swallowing the tooth. If you can’t keep the tooth in your mouth, keep it in a container of your saliva or milk.
If your tooth is fractured, you may or may not need emergency dental care. It depends on the severity of the fracture. Moderate to severe fractures may cause damage to the enamel, pulp, nerves and other tissues. In some cases, a crown can fix the issue. If the fracture is minor, you may be able to leave it alone. However, if you wish to fix it, your dentist can do so with a composite restoration.
If you suffer severe pain, you may have an abscess or infection. You may also have injuries to the gums, cheek, tongue or lips, which can cause severe bleeding. These issues require immediate care. Call your dentist right away.
If you cannot get an immediate appointment, go to the ER. If you are ever in doubt, and cannot reach your dentist, go to the nearest emergency room. The doctors there are able to treat some mouth issues and can at least advise if you should see a dentist.
