While Americans have a 96% caries-free dental rate, the prevalence of dental caries in our country is as high as 80%! Although our young people now pay more and more attention to the aesthetics of the teeth, but the health of the teeth is still not enough attention. And the older, it is aesthetics and health double neglect. Experts emphasize that there are four criteria for healthy teeth: whether the teeth are complete, whether the teeth are straight, whether the teeth are white, whether periodontal health. Dental integrity regardless of the old and young, missing teeth should be timely “fill” “In China, missing teeth is a common disease of elderly patients, but also a common disease.” The main causes of missing teeth in older Chinese people are caries, periodontal disease and trauma. “We should not underestimate the health impact of missing teeth.” , firstly, due to the loss of teeth, patients will lose the teeth’s cutting and grinding of food, which will affect the preliminary digestion of food in the mouth and aggravate the gastrointestinal digestive burden; secondly, the loss of teeth also affects the patient’s articulation function, especially the dental and labiodental sounds; thirdly, after the loss of teeth, the teeth will lose the teeth’s support for the maintenance of the lower 1/3 of the face’s height and for the soft tissues of the lips and cheeks, which will make the lower 1/3 of the face shortening, soft tissue collapse, deepening of wrinkles, sagging of the corners of the mouth, and ultimately affecting the appearance. Fourth, long-term missing teeth, the patient’s alveolar ridge, oral mucosa, temporomandibular joints and muscles and nerves will also undergo degenerative and pathologic changes, and in serious cases, it will even affect mental health and social activities. No matter how old or young, missing teeth should be “filled” in time. Teeth aligned Teeth will lead to displacement of neighboring teeth, deformity, caries Teeth may be caused by a single factor or a single mechanism, or may be a variety of factors or a variety of mechanisms to play a joint role in the results. As these factors affect the growth and development of the bones, nerves, muscles, teeth and soft tissues of the jaw and face, thus making abnormal changes in the jaw and face, resulting in malocclusion. “Not only do many adults pay little attention to their own misaligned teeth, many parents also let their children’s misaligned teeth develop naturally.” Not only do misaligned teeth affect aesthetics, they can also affect health. For example, uneven teeth may lead to displacement of neighboring teeth, deformity, caries, etc., and seriously affect the chewing function. A survey showed that: 87% of men think that women’s teeth ugly will seriously affect the first impression of women; 45% of married men that partner’s teeth are not beautiful will greatly reduce the desire for intimacy, affecting the couple’s feelings; 85% of the white-collar workplace that the teeth are not beautiful will directly affect self-confidence and work status. If you have “Baodi”, “buck teeth”, large gaps between teeth, teeth, teeth crowding and other problems, it is best to solve through orthodontic treatment or surgical treatment. Teeth white Tea tartar, tobacco stains, etc. are the first cause of teeth not white “Bright eyes and white teeth is called beauty, the importance of white teeth.” The color of the teeth is not only the color of the surface of the teeth, but also the color of the dentin that appears through the enamel on the surface of the teeth. However, in China, many people have stained teeth, of which the majority are yellow. The label is selected and entered directly to prevent formatting errors. Tooth staining is mainly divided into endogenous staining and exogenous staining. Exogenous staining, mainly due to the presence of a variety of bacteria on the surface of the teeth, they secrete many sticky substances on the surface of the teeth. When the daily life of tea scale, tobacco stains, certain minerals in drinking water and minerals in saliva adsorbed on these sticky substances, plaque and tartar will be formed, and slowly, it will make the teeth become yellow or black. Endogenous staining, on the other hand, is mainly formed during tooth development, for example, at a young age, there is tetracycline deposited in the dentin, which makes the teeth turn yellow, brown or dark gray, known as tetracycline teeth; for example, if the drinking water contains too much fluoride, it may also lead to fluorosis, with white chalk-colored, brownish-brown plaques on the surface of the teeth. “There is also a situation when the nerve of the tooth is necrotic, the combination of blood pigment and bacterial breakdown products can also darken the teeth.” It is important to treat the different causes of tooth staining. For exogenous stained teeth, generally through the “cleaning” to remove the surface of the tooth pigment, tartar. For endogenous stained teeth, it is necessary to identify the cause of the disease and then treat the symptoms. Periodontal Health 90% of adults suffer from different degrees of periodontitis Periodontal tissues are the supporting tissues of teeth, and healthy periodontal conditions are the foundation of dental health. The results of the Third National Oral Health Epidemiologic Survey show that 90% of adults suffer from varying degrees of periodontitis. Periodontal disease is the main cause of tooth loss in middle-aged and elderly people. The first step to periodontal health is to ensure healthy gums. Healthy gums have the following characteristics: no discoloration of the gums, no swelling, no bleeding, no odor, no pus. Red, swollen and bleeding gums, food impaction, receding gums, longer teeth, bad breath, tooth sensitivity, wider gaps between teeth, weak chewing and loose teeth …… are all signs of periodontal disease. “Periodontal disease is primarily caused by bacterial infections around the teeth.” In the early stage, periodontal disease is mainly manifested by bleeding gums when brushing or biting hard objects, bad taste in the mouth, red and swollen gums, etc.; with the development of the disease, the inflammation around the teeth will be aggravated, which will result in further resorption of the alveolar bone, and ultimately lead to loosening of the teeth, or even loss of teeth. To prevent periodontal disease, first of all, in daily life to master the correct way of brushing. Studies have found that the wrong way of brushing can only clean off 20% to 50% of the dirt attached to the surface of the teeth, while the correct way of brushing can remove 80% to 90% of the dirt attached to the surface of the teeth. Secondly, you should go to the hospital for regular oral checkups to clean your teeth and ensure the health of your periodontal tissues. If you have periodontal disease, the earlier the treatment, the better the result.
