About us

What makes Superkids different?

Pediatric dentists and orthodontists have three years of specialized training beyond dental school. Our goal is to create a “dental home” for children so that they grow up understanding that oral health is an important part of one’s daily habits. We hope that visiting the dental office is something they look forward to. As our patients grow, we monitor not only their current state of oral hygiene but we also monitor their jaw growth and development, identifying any orthodontic needs. In the event that a patient does need (or elect to have) orthodontic treatment, our office is in a position to treat a patient’s hygiene at the same time as their orthodontic treatment, making appointments efficient and thorough.
