Ideally, a child must be assessed for orthodontic treatment between 2 to 5 years, so that early detection and timely treatment can be administered to avoid future problems. Once, most of the permanent teeth have erupted, i.e. during teens, is the best time to get yourself treated as the bone is porous and modifications are easy and quick. Having said this, age is no bar for an effective orthodontic treatment, just that it may take a little longer to get results.
