Trigeminal neuralgia is the most common neurological disease of the brain. The attacks are particularly similar to toothache, so much so that many people, including doctors, treat it as toothache. However, once the disease enters the middle and late stages, not only the frequency of pain attacks becomes more and more obvious, the pain is intensified, and the treatment will take longer and be more difficult at this time, which seriously affects the health of patients. So it is important to learn to distinguish the difference between these two. A. 2 points of difference Duration is different Trigeminal neuralgia: the pain is paroxysmal, and it is a stabbing sensation. Toothache: a constant dull pain that lasts for a long time and feels more stiff. The pain site is different Trigeminal neuralgia: the pain range is larger because it is the whole nerve trunk or several nerve trunks together. Toothache: the pain area is mainly concentrated on the top of the teeth or gums, so it is usually a local pain in the mouth. Trigeminal neuralgia can find “trigger points”, that is, trigger points, and stimulation of these points can cause pain attacks. They are mostly located in the upper and lower lips, nose, nasolabial folds, gums, cheeks and corners of the mouth. It is common in chewing movements, brushing teeth, yawning and other actions. Sometimes a simple opening of the mouth or sound or light stimulation can trigger trigeminal neuralgia. It can range from the size of a fingernail in diameter to a point or a whisker in size. Toothache usually shows persistent pain and will not be triggered by triggering a certain part of the pain. 2.Take medicine test method If the pain does not improve after taking ordinary painkillers, it can be ruled out that it is an inflammatory tooth pain cancer, but a nerve pain. If the pain is not reduced after taking trigeminal neuralgia drugs such as carbamazepine, it can be ruled out that it is nerve pain but toothache. 3.Self-checking dental health method You can detect whether there is tooth decay, gum inflammation or bleeding ulcers in your mouth. If there is no such dental problem or the pain is unbearable, it may be the pain caused by trigeminal neuralgia.
