It is almost always possible to save a broken tooth. If the tooth is only slightly fractured and pain-free, you can make an appointment with your dentist in order to restore it. Aesthetic restorative materials are used to repair broken teeth and are almost invisible since they match the teeth’s natural colour.
However, if your tooth is severely fractured and painful, it is likely that the dentin or pulp is exposed. A root canal and a crown might be necessary to fix it. Contact your dentist and make an urgent appointment, in order to prevent pulpal infection. In the meantime, rinse the area with lukewarm water and follow the above recommendations for pain.
