Auntie Wang, 54, half of her face and toothache has been bothering her for the last ten years, at first she did not care about this problem, thought it was just a general bad teeth, every time the attack of tooth pain is very intense, like being electrocuted, while the left side of the face like a knife cut pain. When the attack of the disease, the left half of Wang’s face can not even touch, let alone talk about washing and brushing the teeth, a long time, Wang’s left side of the teeth rotten, rotten, pulling, the results are “early retirement”. After the tooth extraction, but the pain is still more than, to the hospital examination, only to find that the ultimate culprit causing pain is trigeminal neuralgia, after the most advanced international radio frequency technology without open surgery, the pain is finally resolved. In this regard, the pain specialist introduced that trigeminal neuralgia, known as the “world’s first pain”, is a recurrent, transient and severe pain that occurs suddenly within the branches of the trigeminal nerve in the face, without sensory loss and other neurological dysfunction. Identification of toothache & trigeminal neuralgia 1. If the toothache still does not get better after taking ordinary painkillers, but has effect after taking carbamazepine, then it is ruled out to be inflammatory pain such as periodontal pain, but nerve pain; 2. During the examination, if no relevant inflammation such as caries or periodontitis is found, but the tooth is still in pain, then it may be caused by trigeminal neuralgia; 3. From the pain characteristics , if it is a tooth inflammation, chronic pain is continuous pain, if it is a typical trigeminal neuralgia, in the attack is a lightning sharp pain, usually lasts for a few seconds, several times a day, but unbearable. What symptoms are easily misdiagnosed Trigeminal neuralgia is typically characterized by a paroxysmal, knife-like lightning-like severe pain in the face immediately when a point (trigger point) in the face or mouth is stimulated by eating, washing, brushing, talking, or even walking vibration or wind blowing, etc. Each attack lasts for a few seconds or several minutes, with frequent daily attacks. Trigeminal neuralgia and glossopharyngeal neuralgia can coexist, and sometimes the symptoms are similar and it is not possible to determine which disease is which, which requires consultation with an experienced specialist who specializes in this disease to avoid misdiagnosis. The characteristics of trigeminal neuralgia: it is a recurrent severe pain with short duration and trigger point. Characteristics of dental pain: It is persistent, with significant onset at night, aggravated by hot and cold stimuli, deep pain sites, and no trigger points. Migraine: it is characterized by throbbing headache with visual aura, long duration of attack, up to several hours, and sometimes very intense, sometimes accompanied by nausea and vomiting, without trigger point.
