First call your dentist. Explain your symptoms and ask to be seen as soon as possible. Then ease the pain. Take an over-the-counter pain medicine that works for you, but do not put the pills on your sore tooth. Hold an ice pack against your face at the spot of the sore tooth.
Do not put a heating pad, a hot water bottle, or any other source of heat on your jaw. Heat will make things worse instead of better.
Broken teeth can almost always be saved. Call your dentist and explain what happened. He or she will see you right away. If it's a small break, your dentist may use a white filling to fix the tooth. If the break is serious, a root canal may be needed. Your tooth may also need a dental crown [also called a cap].
If the knocked-out tooth is an adult [or permanent] tooth, your dentist may be able to put it back. You must act quickly. If the tooth is put back in place within 10 minutes, it has a fair chance of taking root again. After 2 hours, the chances are poor.
If the tooth looks clean, put it back in its place [its socket]. If this is not possible, or if there's a chance that the tooth might be swallowed, put it in a container of cold milk. Go to your dentist, or to the nearest dentist, right away. If you get help within ten minutes, there is a fair chance that the tooth will take root again.
If there is bleeding, press down on the part of the mouth that is bleeding. Use a clean cloth to do this. If the lip is swollen, use an ice pack to keep the swelling down. If the bleeding does not stop, go to Dental Emergency at a hospital right away.
First, try using dental floss, very gently and carefully, to remove the object. Never poke between your teeth with a pin or similar sharp, pointy object; it can cut your gums or scratch the tooth surface. If you can't get the object out, see your dentist.
Put a piece of softened sugarless chewing gum in the spot where the filling was lost. This will protect the area for a short period of time. See a dentist as soon as possible.
