Personally, I'm not a fan of two times in braces...or a LONG time in braces because we're waiting for the rest of the permanent teeth to come in! However, I do like to intercept things like habits and skeletal problems while children are still in 'mixed' dentition (primary AND permanent teeth present)...and hold off on comprehensive orthodontics (braces or Invisalign) until at least most of the permanent teeth are in.
The best thing to do would be to have your son seen by an orthodontist to determine if he/she feels that there is anything that should be intecepted with early treatment.
To me, as long as there aren't any skeletal problems, habits, or severe crowding, I would put a child on observation...check them once or twice a year until it's time for alignment and bite correction. This way you can avoid having to pay for two sets of braces, OR have your child in braces for years and years because you're waiting for the rest of the permanent teeth to come in!
