Early evaluation provides both timely detection of problems and a better chance for more effective treatment. Effective intervention guides growth and development, avoiding serious problems later. When orthodontic intervention is not necessary, an orthodontist can carefully monitor growth and development and begin treatment when it is ideal.
By the age of 7, the first adult molars come out, creating the back bite. During this time, an orthodontist can evaluate front-to-back and side-to-side tooth relationships. For example, the presence of new incisors can indicate possible overbite, open bite, crowding or gummy smiles.
