To save the tooth, you must see your dentist right away. Take an over-the-counter pain reliever or apply a cold pack or ice to relieve pain until you reach the dental office.
If the tooth's nerve or blood vessels are damaged, your dentist may want to do root canal treatment. This keeps the tooth from becoming discolored or developing an abscess, which is an infection. Your dentist should do some tests that will show if the nerve has been damaged. These tests are not always reliable right after a tooth is injured. You may need to have them done again at another appointment.
If the dentist decides that root canal treatment is needed, you may need to have the tooth crowned or capped after the root canal. In some cases, it may not be possible to save the tooth. In this case, it will have to be removed. Your dentist will decide the best way to restore the space created by the missing tooth.
