Adolescence, the period from 11 to 21 years of age, bridges the chasm between childhood and adulthood. Adolescence can be challenging as bodies, cognition, and personality go through major transformations, but it is also a time of great joy as confident adults with a clear identity develop. Dentists need to be knowledgeable about the developmental characteristics of this group because some of the cognitive and emotional changes make adolescents vulnerable to new fears. Dentists must tailor behavior guidance to this developing psyche in a way that respects independence and promotes confidence to foster lifelong positive views of dentistry.
