As with any trauma to the mouth, you should consult with your dentist immediately to determine if treatment is required. The dentist will examine the affected area and may take X-rays.
If you are in pain from a broken, cracked or chipped tooth, you may want to take an over-the-counter pain reliever. If possible, keep any part of the tooth that has broken off and take this with you to the dentist.
If a tooth is completely knocked out of the mouth by an injury, take the tooth to your dentist as soon as possible. It may be possible for your tooth to be placed back into your mouth, a procedure called reimplantation.
