The American and Canadian Associations of Orthodontists recommend an initial consultation at the age of 7 years old. At this age, the first permanent molars have erupted and posterior occlusion begins to settle. The eruption of the front teeth also happens around this age. This first consultation allows the orthodontist to detect any significant problem in the occlusion, an important lack of space, a functional shift or an asymmetry. At this point, the orthodontist may recommend regular monitoring to ensure normal teething and growth. If a problem is detected, it is possible that it could or should be improved or corrected with an early treatment (interceptive). Some other problems can be addressed later in development.
