When Hu Hengying and Zhang Chengyu heard that the dentist had to have a nerve extraction test, did you nod silently or stubbornly ask for other treatment methods? Kazuo Xiaofeng, a dentist who has been practicing in Japan for more than 33 years and the chairman of Xiaofeng Dental Clinic, pointed out that we should not only try not to grind our teeth, but also not remove our nerves. The website "KidsHealth" sponsored by Nemours Foundation, a non-profit organization in Florida, USA, points out that bacteria in the oral cavity will produce dental plaque and attach to the surface of teeth, and at the same time, bacteria will secrete acidic substances, erode the enamel on the surface of teeth and invade the inside of teeth for a long time, leading to tooth decay. According to the health education materials of Yukihiro Inoue, M.D., honorary professor of Komeito Women's University in Japan, tooth decay may be caused by the following reasons: eating too much polysaccharide, irregular teeth, eating too many snacks and snacks, and brushing your teeth incorrectly, all of which may leave food and sugar residues in your mouth and allow bacteria who like to eat food residues and sugar to multiply in large numbers. And these bacteria will secrete acidic substances, dissolve and destroy teeth, leading to tooth decay. If the teeth are irregular, there will be more places in the teeth that are easy to get dirty, which will make the tooth decay more serious. Insufficient saliva: saliva can protect teeth and purify bacteria. If saliva is reduced due to various factors such as tension, stress, old age, chronic diseases, etc., it is more prone to tooth decay. What about tooth decay? Is filling a tooth useful? Grinding away decayed tooth tissue will cause a vicious circle. Ren Tianye Saizhi, owner of Amano Dental Clinic, pointed out that many patients who had their cavities, nerves and cavities removed did not fully recover. On the contrary, bacteria grow under the filler, showing black holes. Kazuo Xiaofeng explained that there are many tiny cracks in the enamel on the tooth surface, and bacteria will pass through these cracks and invade the ivory under the enamel. In other words, teeth actually rot from the inside out, and it is useless to remove the outer layer, so bacteria still multiply under the filler. Kazuko Ikemura of Ikemura Dental Clinic also said that many patients drink hot soup in winter and cold drinks in summer, and the filling materials expand and contract when heated, so there is a gap between the filling materials and teeth, and bacteria will come back from the gap and fall into a vicious circle of grinding teeth, filling teeth, cracks and tooth decay. Is it useful to extract nerve from decayed teeth? Nerve pulling will make teeth lose their self-healing ability. Xiaofeng Kazuo pointed out that once the vicious circle of tooth decay tissue began, it sounded the death knell of "nerve pumping". Nerve pumping is now called "root canal therapy" or "pulp therapy" by dentists, but no matter how to change the name, the actual treatment is to pull out the pulp with instruments. However, dental pulp is an important part with healing function, which contains odontoblasts and immune cells. In addition, it can maintain the toughness of teeth, so that teeth are not easy to break and collapse. After tooth extraction, the tooth loses its self-healing ability and can only be gradually destroyed.

After tooth extraction, the tooth loses its self-healing ability and can only be gradually destroyed. Xiaofeng Hefu, an express train that nerve pumping is "tooth extraction", said that as long as a tooth is pulled out, the alveolar bone will take this as a signal to reduce the support for other surrounding tooth tissues, which will eventually lead to the surrounding teeth loosening and falling off. The treatment of tooth decay does not pump nerves and grind away tooth decay tissue, so how to treat tooth decay? At present, the main treatment direction of Japanese dentistry is "non-molar tissue". Other main treatments for tooth decay include ozone therapy, sugar control therapy and laser therapy. Ozone therapy, which is effective in Japan, is not popular in Taiwan Province province at present, while laser therapy has been introduced to Taiwan Province province, but the treatment cost is relatively expensive because there is no medical insurance. As for sugar control therapy, Zhou Ge, director of Japanese Daomaoyu Dental Clinic, pointed out that as long as the sugar intake is controlled, the role of preventing tooth decay and treating periodontal disease can be achieved by preventing acidification. After human beings lose their teeth, they will age in one breath, which will affect their nutrient intake and even increase their mortality. In the survey conducted in Fukuoka Prefecture, the death risk of the elderly over 80 years old who have no teeth is 20% higher than that of the general population. With good teeth, you can live a long and happy life. Prevention is better than cure. Dr. Ji Shu Inoue, a Japanese medical doctor, believes that preventive measures are the best way to fight tooth decay. We can prevent tooth decay by brushing our teeth after meals: we must clean our mouth carefully after meals, and use tooth cleaning tools such as toothbrush, dental floss or dental floss stick to clean our teeth and gaps carefully. Eat less snacks: Eating snacks can easily leave food in your mouth, accelerate bacterial reproduction and cause tooth decay, which should be avoided as much as possible. Avoid eating before going to bed: because the saliva secreted by the mouth will decrease when sleeping, the protective effect on teeth will also decrease. If you eat before going to bed and don't really clean your mouth, you are prone to tooth decay. Check your teeth regularly: It is often difficult for us to find tooth decay before it causes pain. It is recommended to go to the dentist for examination 1 ~ 2 times a year to help you find tooth decay and treat it as soon as possible. An article reviewed by Christine Frank, a dentist in Illinois, USA, also puts forward the following methods to help prevent tooth decay: sugar-free chewing gum: Clinical research shows that sugar-free chewing gum may help to remineralize enamel when chewing after meals; Sugar-free chewing gum containing xylitol may have the effect of making saliva flow, improving the pH value of dental plaque and reducing bacteria, but it still needs long-term research to confirm. Vitamin D: It helps to absorb the minerals calcium and phosphorus in food. Studies have shown that eating foods containing more vitamin D and calcium (such as yogurt) is related to reducing the rate of tooth decay in young children. In addition to diet, the human body can also make vitamin D by sunbathing. Use fluoride toothpaste: Large-scale research shows that regular use of fluoride toothpaste can help prevent tooth decay. Eat less high-sugar foods: The World Health Organization (WHO) recommends that sugar should only account for less than 65,438+00% of the total daily calorie intake per person. If you want to eat sweets, you should also try to reduce the time of eating, so that your teeth have a chance to get rid of the high-sugar environment and re-mineralize.
