Pulpitis can be painful overnight if not intervened, because for the common acute pulpitis, the typical symptom is that the pain is significantly worse at night, because the person itself is in a flat position at night, when the head and face receive more blood, the inflammation will be more pronounced and the pain will be more severe, and many patients with pulpitis will visit the hospital at night and strongly request treatment or extraction of the tooth. The best way is to find the tooth that is causing the pulpitis and have the tooth treated with pulpotomy. The tooth will have immediate relief from the pain after pulpotomy. If the pulp is not available, the pain can only be controlled temporarily by taking analgesic medication and waiting until early in the day.
