Many people think that what we have in our mouths are copper and iron teeth that don’t need any extra care from us. Our teeth age too. And tooth aging starts as soon as it grows out. 6 signs of aging teeth: sensitivity, chipping, decay, looseness, bleeding, and bad breath. Have you ever heard that teeth age too? The World Health Organization has set standards for dental health: clean teeth, no cavities, no pain, normal gum color, and no bleeding. However, due to poor oral care, teeth will appear in the following six conditions, known as “dental aging. 1, tooth sensitivity: manifested by eating some hot and cold sweet and sour food, teeth are extremely sensitive, sharp pain, soreness. The reason is that the surface of the teeth after a long period of wear and tear of dental tissue, resulting in close contact with the nerve of the deep dentin exposed to the oral cavity, food stimulation along these channels to the nerve, triggering pain. Therefore, first of all, we should eat less overly stimulating food, and secondly, we should eat too hard shelled food with the help of tools, but also change the habit of horizontal brushing. 2, caries: with age, the oral mucosa will appear atrophy, resulting in gum recession, tooth gap increases. If you do not pay attention to oral health, food stagnation, bacteria are easy to reproduce on the teeth, so that the incidence of dental caries increased, untimely treatment may cause pulpitis, periapical periodontitis. In addition to the use of fluoride toothpaste to prevent dental caries, the correct brush, but also learn to use dental floss. The gap between the teeth of middle-aged and elderly people is usually wider, the use of dental floss can remove the bacteria on the adjacent surface of the teeth, to prevent bacteria from continuing to destroy the teeth and gums. Flossing after meals should be a flat toothpick, do not use too much force. 3, the surface of the teeth, cracks: this is the “teeth demineralization” performance, is the surface of the teeth enamel in the oral cavity too acidic environment caused by the loss of dentin will be directly exposed to the oral acid environment, in addition to the teeth become brittle, cracks, there will also be a discoloration of the surface of the teeth, no luster and so on. Young people in this situation need to be more careful maintenance care. Prevent tooth demineralization, must change the oral acidic environment, drink less carbonated beverages, timely treatment of tooth decay, less use of the teeth to bite directly into hard food, so as not to avoids tooth avalanches, broken teeth. 4, red and swollen gums, bleeding teeth: if the gums are red and swollen, and accompanied by bleeding phenomenon, you can judge that there is gingivitis, if you find bleeding teeth when brushing or chewing food, you also need to be vigilant. Gingivitis will develop into periodontitis if not treated in time. 5, loose teeth: if the gums red, swollen, bleeding gums at the same time touch the teeth found loose, or found that the root of the teeth exposed, can be judged to have developed into periodontitis. Periodontitis is mostly due to poor oral hygiene, bacterial tartar long-term accumulation of tartar, tartar will stimulate the gums, resulting in inflammation. Therefore, we should pay attention to oral cleaning, morning and evening brushing, rinsing after meals, quit smoking, in order to improve the oral environment. 6, bad breath: the mouth for a long time there is a large breath or bad breath, if not the lungs, stomach diseases caused by the reasons, should consider the oral cavity problems caused by. First of all should deal with the teeth have been decayed, after meals to use dental floss to clean the teeth, occasional inflammation of the gums, hasten to use dental floss to deal with the inflammation parts of the teeth, appropriate medication, bad breath can be eliminated basically.
