Children benefit most from orthodontic treatment in their early teenage years. This is because their adult teeth have had time to develop, but their mouths and jaws are still growing.
For adults, any time could be right, although the treatments available to a fully developed mouth can be more limited than with younger people. But there are still plenty of options available for teeth straightening.
Adults are also more likely to suffer from tooth decay and other dental problems, which can make teeth straightening procedures slightly more complicated. However, with the right dental care, anyone can achieve the perfect smile.
