Pulpitis typically presents with spontaneous pain, paroxysmal pain, and pain due to temperature stimuli. The pain of acute pulpitis often cannot be localized. Only by visiting a regular hospital's dentistry department for pulp opening and drainage can the pain be relieved, followed by comprehensive root canal treatment. Additionally, if it is inconvenient to treat pulpitis pain, one can take oral anti-inflammatory painkillers, apply ice locally, crush a clove of garlic and place it on the affected tooth, or steam one part Sichuan pepper with four parts aged vinegar for ten minutes and then apply the moistened Sichuan pepper to the affected tooth to alleviate the pain. Ultimately, root canal treatment at a regular hospital's dentistry department is necessary. Regular oral hygiene is important, including brushing teeth morning and night, rinsing after meals, and using the internationally recognized Bass brushing technique. Cavities should be detected and treated early.
