Baby teeth play an important role in your child's growth and development. Baby teeth have roles beyond helping your child eat, chew, and make an adorable smile. Without baby teeth to hold proper spacing in your child's mouth, the permanent teeth may not erupt into their proper position, leading to misaligned teeth and the future need for braces. This can also affect the growth of the tongue, jaws and airway. Although they are little teeth, they play an important role in your child's overall health.
