Braces can be done at any age provided the teeth are healthy.
A clinical examination ( consultation) would help understanding the patient’s needs, the smile, the bite, nature of malocclusion, etc and would help us diagnosing the problem better.
Along with a clinical examination, a couple of X-rays, photographs, and models will help us formulating a correct treatment plan for the patient.
Hope this helps.
