Toothache usually does not heal on its own. Temporary relief is mostly an illusion, and will recur if the cause is not removed. Toothache is a common clinical symptom in dentistry, and there are many causes of toothache, mainly including odontogenic diseases such as pulpitis and periapical periodontitis, periodontal diseases such as periodontitis and periapical periodontitis, neurological diseases such as trigeminal neuralgia, and jaw bone diseases such as acute suppurative jaw bone osteomyelitis. The cause of the toothache needs to be clearly identified and treated actively before the toothache can be improved. If you only take anti-inflammatory drugs or painkillers or wait for natural healing, the acute inflammation may be relieved in 3-5 days or even about 1 week, giving the illusion of improvement, but it does not really solve the problem, and the pain may reappear after a period of time. It is recommended that when toothache occurs, you should seek medical attention for examination and treatment for the cause, and not to blindly wait for natural healing or just take anti-inflammatory drugs or painkillers, which will delay the condition and affect the prognosis.
