Space maintainers are essential if your child loses a baby tooth early. Baby teeth are meant to fall out eventually. But they also help form the “paths” that the adult teeth take when they emerge, and help young patients maintain proper alignment for their permanent teeth. If they lose a tooth early, they may have a higher risk of orthodontic complications later in life. With a space maintainer, your child’s pediatric dentist can make sure that early baby tooth loss doesn’t affect their oral development.
