Your child’s primary teeth, also known as the baby teeth, begin to emerge anywhere from 5-7 months of age. Although they begin falling out as early as age 5, they last up until your child is anywhere from 11-13 years old. Some parents believe that it is ok if something happens to these teeth, because they are not permanent. This is false. It is critical that these teeth are kept healthy and strong. These “space savers” can cause unwanted dental issues with your child’s permanent teeth before they even erupt. White or silver fillings can be used to treat cavities or fractures in milk teeth.
