Nerve pain from a missing tooth (clinically known as a chipped tooth) can be effectively relieved by dental filling or endodontic treatment depending on the degree of the defect. 1. If the missing part of the tooth is small or superficial, the pulp tissue is not exposed, but due to the loss of surface hard tissue protection, resulting in pain from hot and cold stimuli, you can carry out restorative treatment for tooth loss, which can be restored to the missing part of the tooth through the filling treatment or full-crown restoration to treat tooth pain. 2. If the missing part of the tooth is deeper, resulting in exposure of the pulp tissue but no obvious symptoms of the pulp, the tooth can be restored after pulp capping treatment; on the contrary, it is necessary to carry out endodontic treatment to remove the inflamed pulp tissue in order to effectively treat tooth pain. It is recommended to consult a doctor for a clear diagnosis of nerve pain to avoid delaying the condition.
