A toothache on the right side with facial pain is usually caused by pulpitis. Pulpitis usually has radiating pain, severe pain, and night pain, hot and cold irritation pain, etc. It is accompanied by ipsilateral facial pain and headache, which requires a clear position of the tooth and then open pulp drainage, which can relieve the pain and can be taken orally with pain medication or anti-inflammatory drugs. Pain medications such as fentanyl, ibuprofen or acetaminophen are usually used. Anti-inflammatory medications can be metronidazole or tinidazole plus spiramycin, amoxicillin, etc. At the same time, root canal treatment is required after the treatment of the tooth, and porcelain crown restoration is recommended after the completion of root canal treatment to ensure the longevity of the tooth. If there are trigger points, you can check whether there are symptoms of trigeminal neuralgia, and you need to go to the neurology department.
