First, we should strengthen our awareness of self-care. As the saying goes, "health care comes first." Many elderly people think that toothache is not a disease, so they put it off again and again, thus losing a good opportunity for treatment, affecting chewing function or a series of oral diseases, and even threatening the whole health. Studies have shown that people's chewing activities can regulate cardiovascular and cerebrovascular flow. Old people with strong teeth rarely suffer from cardiovascular and cerebrovascular diseases. The elderly have many missing teeth, and the food is swallowed before it is fully chewed and digested, which is easy to aggravate gastrointestinal diseases. Second, prevention and treatment of common diseases of the elderly. 1. Tooth wear and dentin hypersensitivity: Some elderly people's teeth are excessively worn, which will destroy the enamel protective layer on the outer layer of the teeth and cause dentin hypersensitivity, which is also known as "sour teeth"; Teeth move forward or face changes, resulting in joint pain near the ear. Therefore, the teeth of the elderly should pay special attention to prevent wear. For the treatment of "acid inverted teeth", sodium fluoride or desensitizing toothpaste can be used as medicine for brushing teeth and mouthwash with desensitizing effect; Food can be rubbed with garlic, or chewed with tea and walnuts; These methods are all good methods circulated by the people. You can also go to the hospital for treatment and treat it by stages with desensitizer and laser. Root caries and periodontal disease: with the increase of age, the gum of the elderly shrinks and the root surface of the teeth is exposed, and the incidence of root caries increases; You should come to the hospital to fill your teeth in time to prevent teeth from breaking due to the continuous development of caries. At the same time, periodontal disease in the elderly is also high, which leads to the decline of chewing function and affects the overall health. Do the relevant periodontal scaling first, which is also commonly known as "tooth washing". Brushing your teeth can't completely replace washing your teeth. 3 Dentition defect and loss: Studies show that more than 90% of the elderly in China have different degrees of dentition defect, but only 30% of the elderly have installed dentures. The loss of individual teeth, because it destroys the integrity of dentition, will affect health to varying degrees. We should repair dentures in time, eliminate defects, restore tooth function, stabilize adjacent teeth and promote overall health. For restored dentures, attention should be paid to cleaning and regular review. 4. Prevention and treatment of systemic diseases: For the elderly with systemic diseases, such as heart disease, stomach disease, diabetes, cardiovascular disease, joint disease, etc., oral diseases can cause such diseases or aggravate their complications, seriously endangering their overall health. At the same time of oral treatment, we should actively prevent and treat systemic diseases. Third, do a good job in prevention and control and develop good habits. 1. Oral diseases should be treated early: tooth looseness in the elderly is mostly caused by root caries, periodontal disease and osteoporosis. As long as these diseases are effectively prevented, the years of tooth loss will be delayed. Therefore, the elderly should treat oral diseases as soon as possible; At the same time, it is recommended to have an oral examination every six months to achieve early detection, early diagnosis and early treatment. 2. Good habits: the elderly should insist on brushing their teeth with warm water every morning and evening, rinse their mouths with clear water after three meals a day, and try to bulge as much as possible; Go to the hospital regularly to remove the stones on the surface of teeth to prevent the occurrence of periodontal disease; It can massage gums, prevent premature atrophy of gums, perform dental tapping exercise and enhance the disease resistance of teeth; Limit the intake of too sweet diet to reduce the incidence of dental caries and wedge-shaped defects; Old people who are addicted to alcohol and tobacco should give up alcohol and tobacco in order to eliminate the chronic bad stimulation to the oral cavity. At the same time, strengthening physical exercise can enhance immune function and contribute to dental care. The elderly should adhere to appropriate outdoor activities and maintain an optimistic and cheerful spirit, which are conducive to enhancing the oral health of the elderly. Let's pay attention to the oral health of the elderly and live a happy life in their later years.
