Our Practice

We provide care that will set the stage for your child’s dental care well into adulthood. Most people who have a fear of the dentist had bad experiences in their childhood. Our main goal is to make sure your child only has great experiences at Cumberland Pediatric Dentistry and Orthodontics, everytime. As both Pediatric and Orthodontic specialists, we know that we need to bring together technologies that protect your child’s health, comforts that help them receive anxiety-free dental care, and amenities that make trips to the dentist fun!
