One or more of your teeth have been damaged. If the surface of the tooth is chipped, your dentist should be able to smooth or repair it with a filling or cap. Make an appointment when you can.
If the tooth is broken off and is sensitive to hot or cold, it's important to see a dentist or oral surgeon as soon as you can for evaluation and treatment.
If the tooth is pushed out of place, the tooth socket (bone) has a break in it. You must be seen as soon as possible by your dentist or oral surgeon. They may be able to put the tooth back in alignment and splint it, if this was not already done by your doctor. This will hold the tooth in place.
If the tooth is knocked out, your dentist may be able to put it back into the socket, if this was not already done by your doctor. Hold the tooth by the crown (eating surface). Rinse it off if it's dirty, and reposition it into the socket by gently biting down. If this isn't possible, place it between your cheek and gums in milk to keep it moist. See your dentist or oral surgeon right away They will put a splint or brace on the tooth to hold it in place. The tooth may reattach and stay in place for months or years. But it may not be the same as a normal tooth. It may discolor or need a root canal to preserve it.
Not all teeth that have been knocked out can be put back in place. If that's the case, put pressure on the socket with a clean, folded gauze pad or cotton swab to prevent bleeding. See your dentist or oral surgeon as soon as you can for further evaluation.
