Primary teeth are also needed to hold the space for the developing adult teeth. They help align the adult teeth as they come in and make sure that the jaw develops properly. If needed, spacers can help make room for the adult teeth to come in.
If you start your children off right when they still have primary teeth, you are setting them up for a life of good oral health. By taking care of their teeth now, you are showing them the way to fight off periodontal disease and cavities. If you don’t take care of their teeth well, your children may lose teeth, which can cause spacing problems when the adult teeth begin to come in.
