Toothache is often a persistent dull pain, confined to the gum area, and can be exacerbated by eating cold or hot foods. And there are many triggers of trigeminal neuralgia caused by toothache. For example, if you are cold, tired, cold, or chewing hard things, toothache is mostly caused by chewing hard things or stimulating the small branches of the trigeminal nerve during tooth extraction, and trigeminal neuralgia occurs; at this time, you should generally avoid the triggers and seek medical attention in time when the problem occurs, and you can use pain medications, such as non-steroidal drugs, or drugs that inhibit neuralgia to suppress trigeminal neuralgia at the earliest stage; at this time, at the early stage, it will not Intractable trigeminal neuralgia may occur. If the pain does occur and lasts for more than a month, intervention is needed: nerve blocks are available in the pain clinic, and patients who have had poor results for a longer period of time can undergo radiofrequency thermocoagulation of the trigeminal nerve, which is more powerful than nerve blocks. Toothache is usually caused by inflammation of the tooth and the structures surrounding the tooth resulting in pain. The trigeminal nerve innervation area is the head and face, and the head and face pain is transmitted to the cranium through the trigeminal nerve; local lesions such as toothache should be treated accordingly for dental and oral diseases. Acute dental caries can be treated intraorally, and gingivitis can be treated symptomatically with anti-inflammatory treatment. Surgical diseases can also be treated orally. As for trigeminal neuralgia caused by toothache, in addition to treating the primary disease, anti-inflammatory and analgesic drugs can also be used to relieve the nerve afferents and provide relief. Treatment requires treatment of the primary disease. Anti-inflammatory and analgesic drugs can be used. Drug therapy is preferred for trigeminal neuralgia, and closure therapy, transcutaneous hemimelia radiofrequency electrocoagulation therapy, and trigeminal nerve microvascular decompression are selected when they are ineffective or fail. Microvascular decompression is a method to treat the cause of trigeminal neuralgia, and it can preserve the anatomical integrity of the trigeminal nerve, so the normal nerve function of the trigeminal nerve can be preserved. Because microvascular decompression has the advantages of obvious pain relieving effect, non-destructive, little side injury, and very low recurrence rate, it is the safest and most effective method for trigeminal neuralgia that is internationally recognized.
