Baby teeth are very important to your child’s health and development. They help him or her chew, speak and smile. They also hold space in the jaws for permanent teeth that are growing under the gums. When a baby tooth is lost too early, the permanent teeth can drift into the empty space and make it difficult for other adult teeth to find room when they come in. This can make teeth crooked or crowded. That’s why starting infants off with good oral care can help protect their teeth for decades to come.
