As the saying goes, “a toothache is not a disease, but a pain that really kills you”. This shows how much people are afraid of toothache. Nowadays, people work hard, stressful, and eat inappropriately, which makes them prone to fire. Once the fire toothache automatically comes to the door, why is this the case? I believe we are curious to know. Toothache caused by fire is usually a bit of a problem with the teeth themselves, and in the mouth, there are usually bacteria and viruses. When a person is healthy, the resistance is strong and can control the development of these bacteria and viruses. Once a person’s resistance is lowered, after the fire, the blood heat goes up, the bacteria will develop quickly and speed up the destruction of the teeth, so that the nerves of the teeth are also stimulated, thus producing a toothache. There are three main types of toothache caused by fire: 1, stomach fire toothache, in addition to feeling severe pain, there will also be red, swollen gums, overflowing pus or bleeding phenomenon. 2, false fire toothache, mainly caused by chronic periodontal disease, manifested as a vague tooth pain, usually light, but after the afternoon and night aggravated, often appear loose teeth, bite weak condition. 3, wind and fire toothache, mostly seen in the early stage of acute pulpitis and periapical periodontitis, manifested as a painful feeling, and a burst of pain, when eating cold things, the pain will be reduced, once contact with hot things will be aggravated, and lead to swelling of the gums. When toothache is caused by fire, there are several things that need to be noted: 1. You should not eat spicy and irritating food as well as smoked and fried food to avoid aggravating toothache symptoms. 2, pay attention to drink more water, eat more fresh fruits and vegetables, is conducive to remove the fire. 3, try to maintain emotional stability, avoid anxiety, anxiety, tension, which will only increase the symptoms. 4.Find out what dental diseases exist. The dental diseases that cause toothache mainly include tooth decay, pulpitis, gingivitis, periodontitis and so on. These dental diseases are usually caused by bacterial infection, among which anaerobic bacterial infection is the main one, in this case, patients should seek medical treatment in time. As long as these dental diseases are gone, then naturally there will be less fire. The toothache problem will also be solved.
