The number of people aged 65-74 in China who have no teeth in their whole mouth reaches 10.51%. Do all people lose their teeth when they get old? In people’s eyes, it is natural for people to lose their teeth when they get old. Therefore, whether in our surroundings or on the TV screen, the elderly aged a wrinkled face and no a tooth mouth, feel with quite smooth, so there is the “old lost teeth” saying. This is a misconception, in fact, the age of teeth can be as long as the age of life, healthy teeth can be a lifelong companion, the main cause of tooth loss is periodontal disease. The current situation: the periodontal health of the country is not optimistic figures show that the existing dental situation of the elderly in China’s urban and rural 65-74 age group: the average number of teeth in the mouth 18.14, the number of people with more than 20 teeth is 57.68%, the number of toothless 10.51%. The main cause of premature tooth loss in the elderly is caused by periodontal disease that is not well treated. To prevent periodontal disease, regular scaling is the most basic and effective measure to remove tartar, the initiating factor of periodontal disease, and reduce the chance of bacterial infection. In developed countries in the West, regular scaling accounts for 90% of the population, while less than 10% in China. From our country, the southern cities are a little better than the northern cities. According to the statistics of periodontal disease department of city stomatology hospital, more than 50 patients are seen every day, about 90% of them come to treatment because of periodontal disease, less than 10% come to scaling for health care teeth, it can be seen that people’s awareness of periodontal disease still needs a great improvement. Misunderstanding: periodontal disease is not a disease, no pain, no itch, no need to cure In the eyes of many people, teeth need to be filled when there is a hole, teeth should be set when they fall out, and “it doesn’t matter if the gums bleed, no pain, no itch, no need to cure”, the true face of periodontal disease “health killer” is not recognized: The loss of tooth decay is a single tooth, while the loss of periodontal disease is a group of teeth or even the whole mouth. From the above statistics, more than 90% of adults have more or less some periodontal disorders, but because the disease progresses slowly, the early stage only manifests as bleeding when brushing teeth or biting food, most of them have no obvious discomfort symptoms, so they often take the attitude of not caring and let it develop, only when the tooth hurts, swells, moves, and can’t eat with strength do they know they have the disease, at this time it is mostly the advanced stage of periodontal disease, and they can only The teeth can only be seen in advance “laid off”. People still have doubts about scaling: is it good for teeth to be scaled regularly? Can I wash my teeth badly or loosen them? Guo Lixin, director of dentistry, says that people’s fears are justified. Some irregular clinics or personnel without professional training may cause damage to the teeth, unclean subgingival tartar may aggravate the symptoms of periodontal disease, and incomplete disinfection may also infect the disease, but if you go to a regular medical institution, these problems do not exist, and with advanced equipment as a guarantee and the regular operation of professionals, scaling will not damage dental health. Periodontal disease is related to the health of the whole body, must pay attention to periodontal disease not only leads to local tooth loss, damage to the oral chewing function system, but also can cause or aggravate some systemic diseases. Recent studies have confirmed that periodontal disease is associated with acute myocardial infarction, chronic coronary heart disease, acute or subacute infective endocarditis, can aggravate diabetes, can cause premature birth and low birth weight babies in pregnant women, and can also lead to the occurrence of chronic gastritis, among other conditions. Regular dental scaling can effectively prevent periodontal disease. Dental cleaning is not the exclusive preserve of young people, regardless of age, regular dental cleaning is necessary. Many elderly people already have periodontal disease, a lot of tartar, oral odor, scaling can not only clean the mouth, but also stop or delay the development of periodontal disease, so that periodontal tissue health is relatively stable. 80-year-old people have 20 teeth, this goal has become a reality in developed countries. In our country, to achieve this goal still needs the joint efforts of oral health workers and people persistently. Tips: 1, periodontal disease is important in the prevention, one is to develop a good habit of brushing in the morning and evening, rinse after meals, the second is regular dental cleaning, healthy adults generally six months to a year to clean the teeth, periodontal disease patients according to the doctor’s request, the interval is relatively short. 2, adhere to treatment, lifelong maintenance. 3, smoking is harmful to periodontal health, can aggravate periodontal disease, advocate smoking cessation. 4, periodontal disease treatment is very professional, it is best to choose a professional regular dental clinic.
