A broken tooth is a normal tooth with a defect, which can be categorized according to the degree of defect into a defect that does not reach the pulp and a defect that reaches the pulp. The former can be restored by filling treatment to restore tooth form and function; the latter requires root canal treatment and crown restoration to restore tooth form and function. 1. Chips that do not reach the pulp: If the depth of the chip is shallow or partially away from the pulp, the decayed tissue can be removed directly and the tooth form and function can be restored through filling treatment; if the depth of the chip is near the pulp, indirect pulp capping should be carried out first and then filling treatment should be carried out. 2. Tooth defect that reaches the pulp: if the pulp is exposed during the removal of carious tissue, direct pulp capping should be performed before filling treatment, and the condition of the tooth pulp should be closely observed after the operation, and root canal treatment and crown restoration should be carried out in a timely manner if there are symptoms of pulpitis; if the depth of the defect reaches the pulp and there are symptoms of pulpitis, root canal treatment should be carried out before crown restoration in order to restore the form and function of the tooth; When you find a bad tooth, you should go to a regular hospital as soon as possible to receive treatment, and you should listen to the doctor’s guidance on what kind of treatment should be used, and treat the symptoms under the doctor’s guidance.
