Occlusal pain after pulp extraction may be due to the presence of occlusal high spots in the temporary sealing material, which should be adjusted to grind the occlusal high spots, or it may be due to the periapical nerve stimulation, which can be left untreated for the time being, and can be observed, as follows. 1. The presence of occlusal highs in the temporary sealing material: root canal preparation and root canal disinfection are required after pulp extraction, and the temporary sealing material is used to temporarily close the cavity after sealing the medication inside the root canal. If occlusal highs exist, they may cause periodontal trauma, leading to occlusal pain, and the occlusal highs should be ground away. 2. Periapical nerve stimulation: When extracting the pulp, the periapical nerve may be stimulated and occlusal pain occurs, generally no special treatment is needed, and the pain will be gradually relieved in about 3~5 days. There may be other reasons for occlusal pain after pulp extraction, so it is recommended to go to the hospital in time for early targeted treatment.
