    Patient Testimonials

    It's is a pleasure to have not only the parents be hightly satisfied, but the child too! Kudos to all! You have all made such a positive impact on my children, how is it that theytoo, remind "Mommy and Daddy" to floss then brush at night so we may also keep the "critters" out of the whole family's mouths . . . priceless!

    Care in Our Office


    Free Exams Under 2

    The American Academy of Pediatric Dentistry recommends that children begin dental care with the eruption of the first baby teeth. We support this commitment by offering free exams in our office to all children under the age of 2.



    Sealants today are considered an important part of preventive dental care. They are beneficial in preventing dental caries on premolars and molar teeth on children and adults. A dental sealant is a protective barrier placed in the pits and fissures of teeth by sealing out food and bacteria which result in cavities. Sealants can reduce the incidence of cavities 86% the first year and up to 58% after 4 years. In our office, a licensed dental associate will apply dental sealants. We also guarantee our sealants for 2 years from the initial placement.


    Sedation Dentistry

    For children requiring extensive treatment, we offer the option of sedation right in the comfort of our office by a Board Certified Anesthesiologist. As an out-of-the-office option, our dentists have privileges at Morristown Hospital.

    Community Immersion

    Community Immersion

    We feel a strong responsibility to be an engaged and affirmative member of our community by sponsoring sports teams, and participating in health and wellness fairs. We also facilitate an Early Childhood Dental Education program that engages hundreds of preschoolers in Morris County each year. In addition, we like to connect with our patients and their families outside of their dental appointments through our annual ice cream social and Mission Gratitude, a family fun event honoring members of fire and police departments and the military where children can climb in a fire truck, write a thank-you note to a soldier and watch a demonstration by service dogs. We hope you will find that the doctors and staff of Pediatric Dental Associates of Randolph are committed to exceptional oral care for children and so much more.
