Absolutely! They are the smile of your child, they allow your child to eat, to speak correctly, and they hold the space for the permanent teeth to come in the correct position. Some baby teeth stay in your child’s mouth until about 11 years of age when the permanent ones are ready to grow-in. If your child has dental caries, he or she may lose the necessary space for the permanent teeth to come into the mouth straight. This will not only cause misalignment of the teeth, but may also cause pain, infection, and damage to the permanent dentition.
