Early Childhood Interceptive Treatment Therapy

The purpose of early orthodontic treatment is to prevent more serious dental issues from arising in your child’s future. With Early Childhood Interceptive Treatment Therapy, Dr. McMillen will optimize your child’s bite and alignment. This will prevent bad bites or crooked teeth from worsening over time so your child will never need more serious orthodontic treatment in the future. This is a gentle and successful process that will save you time and resource, and keep your child healthy and confident.
