Infant Oral Health Avoid chewing food and then feeding it to your baby. Bacteria from tooth decay can be transmitted to children through the saliva of caregivers (parents or babysitters). Therefore, caregivers of infants and toddlers should also take good care of their mouths and avoid chewing food before feeding their babies. A balanced diet A balanced and adequate diet of the five major nutrients is needed for healthy teeth. Therefore, from the time of adding complementary foods, children should develop the habit of eating more fiber foods, drinking more water, and eating less sugary foods. In addition, it is also important to pay attention to the speed at which your child eats. Because children who have the habit of containing rice are especially prone to tooth decay, and it often happens at the interface where it is not easy to be found, so you should make it a habit for your child to finish the meal within a certain time. Avoid your baby sleeping with a bottle in his mouth or drinking milk before going to bed Your child sleeping with a bottle in his mouth for a long time or drinking milk before going to bed will cause his teeth to be immersed in an acidic environment for a long time, which will cause decalcification of milk teeth and lead to tooth decay over time, so you should avoid it. Starting from the age of one, take your child for a thorough oral examination once every three months to six months. Early detection and early treatment can reduce the occurrence of early caries in children, so the whole family should do oral examination once every six months.
