Many mothers and fathers think that it doesn’t matter if their baby’s baby teeth are growing well or not, they will have to be replaced sooner or later anyway. In fact, this is a wrong concept, baby’s milk teeth have the functions of chewing, pronunciation, beauty and maintaining the space for permanent teeth to erupt. If the milk teeth are not well protected, it will lead to tooth decay and misalignment, and in serious cases, it will affect the roots of the teeth, which will affect the jaw development, eating and speech function of the baby, and even affect the overall health of the child. Therefore, baby’s dental care should be done from infancy.
