Certified Specialists

All dentists at Smart Pediatric Dentistry are either board certified or board eligible pediatic dental specialists.

This means that after dental school, they attended two additional years of specialty training focused primarily on treating the dental needs of children ages 0-18 years of age.  Above and beyond a pediatric dentist can take additional board exams both writen and oral to become board certified by the American Board of Pediatric Dentistry.

Our main focus as pediatric dentists are to inform and teach parents about their child’s oral health, do the highest quality dentistry possible, do it safely, and do it in a way that is most comfortable for our patients and parents.
