The National Health Commission held a press conference on the 6th to introduce the relationship between seasonal solar terms and health (Liqiu). At the meeting, Zhou Yongsheng, chief physician of Peking University Stomatological Hospital, pointed out that some parents believe that their baby teeth will have to be replaced sooner or later, so they don't need to be replenished if they are broken. This concept is wrong. Zhou Yongsheng said that humans have two sets of teeth, deciduous teeth and permanent teeth. deciduous teeth not only directly affect chewing function, but also affect children's nutrient absorption and physical development. At the same time, deciduous teeth are also the "guide" for the eruption of permanent teeth. If the baby teeth are broken or fall out too early, it may cause abnormal eruption of permanent teeth, such as crooked or unable to grow. In addition, a healthy set of baby teeth can help children with normal pronunciation. If the baby teeth, especially the anterior teeth, are missing or extensively decayed, the child's pronunciation and learning to speak will be affected, and some children may be ashamed to speak, affecting their mental health. Zhou Yongsheng introduced that dental caries is a common dental disease among children. Parents should pay attention to the prevention and active treatment of dental caries in primary teeth. Specifically, they need to pay attention to three aspects: first, they should clean their children's mouths and help them develop the habit of brushing their teeth in the morning and evening. The second is to recommend preventive measures such as pit and fissure sealing and local fluoride application, which can effectively prevent dental caries. Groove sealing is a specialized resin material adhered to the surface of teeth, covering the grooves and cavities that are particularly prone to dental caries, especially on the occlusal surface, to prevent the invasion of food residues and bacteria. It is recommended to perform pit and fissure closure for deciduous teeth at the age of 3-4, and for permanent teeth at the age of 6-8. Thirdly, it is recommended to go to the dental clinic for oral examinations every six months to achieve early detection and treatment of oral problems. Good oral hygiene habits can benefit children for life. Zhou Yongsheng pointed out that for adults, many people think that losing one tooth does not affect eating and ignore it, but this concept is also wrong. Because once a tooth is missing, its adjacent teeth on both sides will lose support and gradually tilt and shift towards the vacancy. At the same time, the teeth on the opposite side of the jaw will also excessively elongate towards the vacancy due to the loss of biting force, leading to a series of chain reactions such as food impaction, caries, periodontal disease, bite trauma, etc., seriously damaging oral health. How to prevent premature loss of teeth? Zhou Yongsheng said that sticking to daily brushing and flossing, and regularly cleaning 1-2 times a year, can effectively prevent common oral diseases such as dental caries and periodontal disease. In addition, bad habits such as using teeth to lift bottle caps and biting hard objects should be avoided to prevent tooth splitting. Zhou Yongsheng said that if there is really a missing tooth, it doesn't matter. Go to the dental restoration clinic for timely repair: timely dental implantation, filling of missing teeth, can better restore chewing function, maintain oral stability and health. (New Society)
