With a mouthful of beautiful teeth to taste the sweet and sour of life, there is always love teeth to accompany the prevention of dental disease in a timely manner, the correct care never give up; accumulate the love of teeth little by little, and write the melody of life together. The number of teeth is 28-32 for normal people, and the goal of dental health for the elderly in China is more than 20. However, many people do not care about their teeth and bring damage to their teeth, which leads to their teeth basically breaking down or falling out in their old age. This has led to the misconception that teeth will fall out in old age. Is it true that people will lose their teeth when they grow old? No! Teeth, like other organs of the body, do age, but except for some familial factors and systemic diseases, tooth loss in the elderly is mainly caused by dental diseases rather than natural loss. In fact, if we take good care of our teeth, the elderly can also have a healthy set of teeth. In order to not lose teeth in old age we must do this! 1, first of all, we must have a sense of dental care, in my many years of medical practice found that all people who pay more attention to their teeth, the general dental condition is better. 2, to pay attention to dental cleaning, clean up the teeth at any time, after eating something easy to store food in the periodontal, if not removed in time, it is easy to make bacteria multiply and cause dental disease, so we recommend that after eating something to rinse your mouth, if possible, you can use the flosser to clean, the food stuck between the teeth, it is best to use dental floss to remove. 3. Do some knocking training every day, gently knocking the upper and lower teeth against each other dozens of times, to ensure that all the teeth are in contact, do not use too much force, and be careful not to bite the tongue. This can be done in the morning after brushing your teeth and at night before going to bed, for about ten minutes each time. Frequent knocking can enhance the sturdiness of your teeth. 4. Avoid eating foods that are too hard, because teeth are more brittle and often biting hard objects can easily crack teeth. 5, the most important thing is to develop good oral hygiene habits, adhere to brush your teeth every day, rinse your mouth after meals. 6, to regularly check the teeth, to achieve early detection, early treatment. We recommend that a comprehensive dental examination and thorough cleaning should be done once every three months to six months. 7.Eat foods that are good for teeth, foods that are healthy for teeth do exist, such as radish and celery can promote blood circulation in periodontal tissues and help clean teeth, and at the same time have a massage effect on periodontal tissues, so it is recommended that older people should eat more. 8.Change toothbrush and toothpaste regularly. It is recommended that you change your toothbrush once every three months, because in the process of brushing, food residues and some oral bacteria will be hidden in the toothbrush, which is a bad hidden danger for a long time, you must change your toothbrush regularly. Long-term use of the same toothpaste will produce a dysbiosis of the oral flora, so it is necessary to regularly replace the toothpaste. In addition, it is recommended that the whole family should not use one toothpaste, for example, the elderly have elderly toothpaste, children have children’s toothpaste, young people use young people’s toothpaste, children can use fluoride toothpaste, young people can use whitening and tooth protection toothpaste, the elderly can use desensitized toothpaste. Experts point out that there are three major causes of tooth loss: calcium deficiency, dental caries (two high incidence periods), and periodontal disease. Periodontal disease refers to the invasion of gums, periodontal membrane, alveolar bone and dental bone, lingering, destructive disease. The most common of these are gingivitis and periodontitis, which may eventually develop into periodontitis if gingivitis is not treated promptly and effectively. It is one of the most common dental diseases in the elderly and is the main cause of tooth loss in the elderly.
