Meet The Doctors
Pediatric dentistry is a distinct field that focuses on the oral health and unique needs of infants, children and young adults with special needs. Pediatric dentists complete a standard four-year degree in dentistry followed by an additional two to three years of rigorous, specialized training in pediatric dentistry. This specialized program of study and hands-on experience prepares pediatric dentists to treat their patients and start them on a path to a life of healthy teeth and happy smiles.
