What’s the best age to seek orthodontic treatment?

The ideal age for the first orthodontic check-up is 7 years, after the eruption of the permanent first molars which are the key to occlusion (“bite”). However, in some cases where there are obvious signs of skeletal deficiency or excess, a child may be seen as early as 5 years old. There is no age limit for treatment. Any adult may be treated as long as the bone and other supporting tissues are healthy.
