If the toothache is a common dental caries, the pain can be relieved by local repair, but if it is a deeper caries, it may cause pulpitis or even periapical inflammation, it is necessary to treat the disease by root canal treatment to achieve complete pain relief. If the toothache is caused by acute peri-coronitis, which is common in oral surgery, it is necessary to relieve the pain by local rinsing and systemic medication, and after the pain is relieved, the blocked tooth is extracted. In general, if the pain is not severe at night, it is recommended to take basic anti-inflammatory and pain-relieving drugs by mouth, such as cephalosporin and metronidazole, and ibuprofen for pain relief, and then go to the hospital to check the tooth as early as possible during the day.
