Every parent loves their children, it’s human nature. However, many parents do not know how to love? Parents are often only concerned about their children’s education and growth, but not their children’s dental health. In fact, teeth are the most valuable non-renewable resources, lost will not come back. Some parents tend to think that, anyway, milk teeth still need to be replaced, even if they are broken, do not care. This realization is extremely harmful. Unbeknownst to us, milk teeth play an extremely important role in a child’s development. Milk teeth can help the chewing of food, increase the full absorption of nutrients, improve the child’s appetite; chewing power of milk teeth can effectively stimulate the development of the jawbone; can guide the healthy development and growth of the inherited permanent teeth; the replacement of milk teeth and permanent teeth is in accordance with the established order of orderly replacement, if the milk teeth are lost too early, can lead to the replacement of the order of confusion, resulting in the crowding of the permanent tooth rows are not aligned, which not only affects the aesthetics, but also prone to caries due to poor oral hygiene; the child due to the loss of teeth caused by psychological adverse impact on the child, and also the loss of teeth. The psychological impact of losing teeth is also not to be underestimated. Therefore, it is very scientific and necessary to treat milk teeth well, preserve milk teeth and replace them according to physiological laws. I hope that parents will love their children scientifically and will not blindly spoil their children and bring them a lifetime of pain. This is also my sincere advice and suggestions for you as a dentist. Let’s work together to support a blue sky for the child’s dental health.
