Our Philosophy

At Pediatric Dental Specialists, our goal is to eliminate the risk of dental disease and related problems for your child. This requires the cooperation of the child, parents, and the dentist. We believe that prevention of disease is far more enjoyable, less costly, and more comfortable for all concerned. Dental health also depends upon good habits, such as proper diet and regular dental visits. Our practice encourages first dental visits at the time of a child’s first birthday.

Community Involvement

Pediatric Dental Specialists believes in giving back to the community whenever we can. We are involved in a variety of great programs, including Give A Kid a Smile, YSA Soccer Sponsor, Billings Public Schools Saturday Live Sponsor, and the Cleft Palate Clinic. We also sponsor various clubs and sports in the Billings Public Schools and Billings Catholic Schools.
