According to reports, at present, China’s babies suffering from dental caries proportion is quite high, the reason found that the congenital insufficiency of children suffering from dental caries is a reason. Experts pointed out that the mother’s body is a special environment and material basis for the growth and development of the fetus, the good or bad development of the baby’s teeth, mainly depends on the fetal period and the first year of life after the nutrition. Enamel underdevelopment, mainly because of the fetal period when the embryonic formation of teeth, pregnant women lack of calcium or take certain drugs. That’s why it’s important for “moms-to-be” to get enough calcium during pregnancy. Experts point out that pregnant women should maintain a normal, adequate and balanced diet, with a balanced intake of rice, fruits, vegetables, milk, fish and meat, in order to supply the calcium, phosphorus and vitamins needed for the baby’s teeth. Periodontal disease mothers are more likely to give birth to preterm babies According to reports, pregnant women with bad teeth, more harmful than smoking, drinking alcohol, will lead to preterm birth and low weight of the fetus. It is understood that periodontal disease is one of the most common diseases in the oral cavity, “accounting for 80% to 90% of dental patients.” And periodontal disease and loss of teeth, a greater danger to the physical and mental health of people, especially mothers during pregnancy and childbearing due to endocrine changes, gum tissue flaccid, bacterial reproduction of toxins produced will stimulate inflammation of the gums. If a pregnant woman swallows the inflammatory exudate, it can affect the health of the whole body and the fetus, because these inflammatory mediators enter the bloodstream and have a toxic effect on the embryo. It has been shown that 18% of preterm low-birth-weight babies are born to mothers with periodontal disease, and that the risk of preterm low-birth-weight babies in mothers with periodontal disease is 7.5 times higher than in the control group. Therefore, “mothers-to-be” should pay close attention to their oral health during pregnancy, pay attention to oral hygiene, adhere to brushing, regular checkups and assessment of periodontal health, periodontitis should be done in a timely manner for periodontal disease systemic treatment to control the disease. Generally speaking, dental treatment is not recommended during pre-pregnancy (first trimester pregnancy) if it is not an emergency; mid-pregnancy (fourth to sixth month) can be treated under the guidance of a doctor; late pregnancy (second trimester pregnancy) is not suitable for prolonged dental treatment (such as extractions, etc.). Healthy baby teeth are the foundation of healthy permanent teeth Many parents are very nervous about their children having cavities in their permanent teeth, but some first-time parents are a little unconcerned about their children having problems with their baby teeth. Unbeknownst to them, if a child doesn’t have healthy milk teeth, their permanent teeth will also be adversely affected. Milk teeth in addition to the function of chewing food, but also to promote the growth and development of the pediatric face and jaw muscles and other functions, if the number of missing milk teeth will also lead to a decline in the chewing function of the baby’s face of the jawbone will be due to the lack of physiological stimulation of chewing and underdevelopment of the face asymmetry. In addition, 20 milk teeth also play an important role as the new permanent teeth eruption “guide”, so that the permanent teeth inherit and along the position of the milk teeth eruption. In addition, normal and complete milk teeth help children to pronounce words correctly. It is worth noting that if the milk teeth are missing too early, the neighboring teeth in the vacant space will fall into the gap and occupy the position where the permanent teeth would have erupted, resulting in the permanent teeth not erupting “at the right time” and “at the right place”. As a result, the permanent teeth may grow out of alignment, or even have an abnormal occlusal relationship. Therefore, milk teeth on the child’s early development is very important, the child’s oral health care work should start from the milk teeth period. Use fluoride toothpaste with caution for infants and young children under the age of 3 Some parents are aware of the importance of children’s oral health care, but lack the correct knowledge of oral health care. Therefore, parents should pay attention to a few points in the cultivation of young children’s brushing habits: First, the head of the toothbrush should not be too large, in order to avoid damage to the oral tissues; second, young children to use soft bristles of the toothbrush, otherwise the bristles are too hard easy to stimulate the child’s oral tissues, so that they resist brushing their teeth; third, young children’s toothpaste dosage should be appropriate, especially now that a lot of toothpaste fluoride, a small amount of fluoride to help protect the teeth, but more than that would be Harmful to the body. It is recommended that infants and young children under 3 years old should use fluoride toothpaste with caution, and the amount of fluoride toothpaste for preschool children should be the size of a soybean each time they use it.
