In fact, teeth are also an organ in the human body, with the age of aging will also occur, but the teeth are the hardest tissue in the body, can not see the “aging”, but the surrounding gum soft tissue and so on will occur shrinkage, degenerative changes, coupled with some systemic diseases (such as hypertension, coronary heart disease, etc.) and local The stimulation of some systemic diseases (such as hypertension, coronary heart disease, etc.) and local factors, the so-called “old tooth loss” occurs, that is, the teeth fall out when old. In fact, the most important reason for loose teeth is periodontal disease! So how can we prevent periodontal disease? It is actually very simple, please remember the following suggestions: 1. Brush your teeth carefully Our teeth are covered with plaque and soft scale, if these plaque and soft scale are not cleaned for a long time and accumulate on the surface of the teeth, it will cause gum disease. We have been asked to brush our teeth since we got teeth. This is because brushing twice a day removes plaque and soft tartar from the teeth, removes food debris, and reduces bacteria in the mouth. Incidentally, brushing the tongue can also reduce bacteria in the mouth and help prevent periodontal disease. 2, please use dental floss Flossing is the second step in the oral health care routine. Flossing helps us to remove food debris and plaque from the adjacent surfaces of teeth that cannot be brushed by toothbrushes, remove irritants and maintain periodontal health. 3.Rinsing with mouthwash Rinsing with mouthwash is the last step of oral daily care, which can help us remove the residue debris left in the mouth after brushing and flossing. The use of antibacterial effect of mouthwash can not only antibacterial, but also have the role of fresh breath. 4, regular oral examination and cleaning Once or twice a year oral examination and professional dental cleaning can remove their own can not be removed at home, such as calculus, eliminate oral hidden problems, prevent oral diseases. Many people think that as long as they brush and floss well, there is no need to see the dentist regularly. In fact, professional cleaning is necessary to reduce the risk of developing periodontal disease. Dentists use specialized tools to remove disease-causing factors, as well as being able to check the health of your mouth and find and fix your oral problems before they become serious. The orthodontic process is based on the fact that the alveolar bone can remodel itself by pulling the teeth with light force to straighten the uneven teeth so that bacteria cannot hide and the amount of plaque can be easily controlled by the self-cleaning action of the mouth or our daily cleaning, which is the key to achieving a long-lasting preservation of the number of teeth and their longevity. Therefore, a regular orthodontic procedure will not cause premature “tooth loss”.
