Mothers want their babies to have healthy and beautiful teeth, but babies inevitably have uneven teeth and cavities as they grow up. Some parents mistakenly believe that this situation is caused by a lack of calcium, but I do not know that the incisor tooth decay in infants and children may also be bottle caries, is caused by the babies sleep at night holding the bottle to sleep. 4 kinds of feeding misconceptions to pay attention to 1, drinking milk to sleep Many babies have the habit of drinking milk to sleep, in the long run, the fermentable sugars in milk remain around the teeth for a long time, and this liquid provides the best medium for acid-producing bacteria. Unable to dilute the milk in the mouth in time, the self-cleaning effect of the mouth will be greatly diminished. In addition, prolonging bottle feeding, even to more than 3 years old, will make the baby’s chance of tooth decay increase. 2, excessive use of pacifier The pacifier can mainly play the role of soothing the baby. For premature babies or children with delayed intrauterine growth, sucking on a pacifier is a comforting stimulus that can promote weight gain. Experts say it’s best to stop using a pacifier after 10 months of age. Frequent pacifier sucking may cause the child’s upper front teeth to protrude and form an open bite. 3, not adding complementary food on time If you do not add complementary food to your baby on time, it will affect your baby’s chewing function and teething, and the nutritional needs of your baby’s rapid growth and development will not be met. Timely addition of complementary foods for baby chewing, biting and other functional training is of great significance, related to the sensory function of the mouth and the development of the upper and lower jaw. Some mothers let their babies drink from a bottle when they are a few months old and their hands are not strong enough to support the bottle, so they let their babies drink from the bottle by themselves. This will cause the baby’s teeth to bite back, because under the upper lip is the child’s very delicate maxillary dental bed bone, which is often under the pressure of the bottle will affect the development, so that it can not grow forward normally. Bottle caries not only brings harm to the child’s oral cavity locally, but also affects its growth and development, thus it is very important to prevent bottle caries. The method to effectively prevent bottle caries 1, bottle can not “sleep with” First of all, we should control the feeding time, preferably in about 15-20 minutes, never let the child sleep with the bottle. Secondly, we should pay attention to keep oral hygiene after feeding, and feed plain water in appropriate amount, which can play the role of cleaning the mouth. 2. Reduce the intake of sugary foods As young children grow up, parents need to adjust their diet from 6 months onwards to gradually add supplementary foods and reduce the intake of sugary foods. Infancy is an important period when all the milk teeth and most of the permanent teeth are formed and calcified. Therefore, supplying sufficient protein, vitamins and foods rich in inorganic substances such as calcium, iron and phosphorus will be beneficial to the normal development of teeth. 3, protect teeth from childhood After each nursing or feeding, parents should put gauze on the index finger and scrub the tooth surface with water. As young children grow up, with the help and supervision of parents make children gradually master the correct way to brush their teeth. In addition, children should be taken to the hospital for dental checkups every 6 months from the time their first milk teeth come in, and tooth decay should be treated promptly.
