The American Dental Association (ADA) defines pediatric dentistry as an "age-defined specialty that provides primary and comprehensive preventive and therapeutic oral health care for infants and children through adolescence". The primary reason for pediatric dentistry is that infants, children, and adolescent have special physical and psychological needs. Children need different approaches in dealing with their behavior, guiding their oral and facial growth and development, and helping them avoid future dental problems. A pediatric dentist is uniquely qualified to meet these needs.
A pediatric dentist is a specialist with an additional 2 – 3 years of training after dental school. Pediatric dentists emphasize the establishment of trust in children in order to build a cooperative relationship. Accordingly, one of the main skills of pediatric dentists is child psychology. Pediatric dentists utilize multiple communication styles and approaches to make dental visits enjoyable.
