Children sleeping with pacifiers are prone to tooth decay

　　September 20 is the 23rd national "Tooth Love Day", the theme is "Healthy Oral, Happy Family". Sui Lina, director of the Department of Stomatology of Zhengzhou People's Hospital, introduced that dental caries, commonly known as "cavity teeth", is listed by the World Health Organization (WHO) as one of the three major diseases in the world, and it is the most common among adolescent oral diseases.

　　Children sleeping with pacifiers are prone to "cavity teeth"

　　According to Sui Lina, "cavity teeth" is medically known as dental caries. The specific pathogenesis is that the bacteria in the oral plaque (a film formed by bacteria in the oral cavity and other sticking to the surface of the teeth) use sugar as food to feed the bacteria. When sugar is fermented to produce acid, cavities will appear when teeth are eroded by acid for a long time.

　　Why do so many children have "worm teeth" today? The doctor said that this has a lot to do with the child's like to sleep with a bottle. When infants and young children sleep with a feeding bottle, the secretion of saliva decreases, which weakens the function of oral cleaning. In addition, the milk is fermented in the mouth for a long time, which can easily damage the structure of the deciduous teeth. The sugar in the milk powder will also gradually corrode the baby's teeth, causing "Bottle caries".

　　Sui Lina said that compared with adults' permanent teeth, children's deciduous molars have many and deep grooves, pits and gaps on the maxillofacial surface. The plug stays and is not easy to clean. In addition, children sleep for a long time, which is conducive to bacterial reproduction, causing deciduous teeth to be easily damaged. Therefore, changing the habit of sleeping with a bottle in infants and young children can improve the occurrence of "cavity teeth".

　　Brush your teeth frequently and eat less sugar, "cavity teeth" can be completely prevented

　　The newly completed National Oral Health Epidemiological Survey shows that the prevalence of caries in preschool children and primary and secondary school students has dropped significantly. Among them, the caries prevalence of deciduous teeth in 5-year-old children has dropped from 76.6% to 66.0%, and the caries prevalence of permanent teeth in 12-year-old students. This has dropped from 45.8% to 28.9%, but this is still far from the target of 90% caries-free 5-year-old children proposed by the World Health Organization and the International Dental Federation.

　　Among these oral diseases, the most harmful to the human body is also "cavity teeth". According to Director Sui Lina, adolescents and children suffering from "tooth decay" will experience pain in their teeth after eating, which affects their chewing function and hinders digestion. In addition, if there are many "worm teeth", chewing food on one side for a long time will also affect the development of the jawbone, resulting in abnormal oral and facial shapes.

　　The onset of dental caries begins at the crown. If it is not treated in time, the lesions will continue to develop and form cavities until the crown is completely destroyed and disappeared. Untreated cavities do not heal on their own, and the end result of their development is tooth loss.

　　An important reason for suffering from "cavity teeth" is that the oral hygiene is not enough, but many people don't pay much attention to the baby's oral care. The reporter did a small survey among friends who already have children. Most parents said that they do not often brush their baby's teeth. In addition to worrying that brushing will affect their children's future teeth neatness, they mainly feel that "deciduous teeth will have to be replaced sooner or later", and it doesn't matter if you brush or not. .

　　In Suilina's view, tooth decay is completely preventable. First of all, eat less sugar, not just candy, but all sweets. Secondly, we should pay attention to cleaning the mouth of children, brush their teeth regularly every day, especially remember to brush their teeth or rinse their mouths after eating sweets, and develop good oral care habits from an early age.

　　The specific method is to wrap a cotton swab or index finger with gauze, dip it in boiled water or light salt water to scrub the child, once a day in the morning and evening. After the baby's deciduous teeth are basically fully erupted, you can use a toddler toothbrush to brush your child's teeth every day. Brush not only the outside of the teeth, but also the occlusal surfaces of the teeth and the inside near the tongue. "As long as the environment for caries to survive is completely destroyed, caries will naturally not come to the door." Sui Lina said.
