Darren Wong, DDS

I always recommend all my aligner patients have clean teeth before their scan or impressions so that they can have the best outcome. Plaque and debris can interfere with the impression set and result.

Calculus can build up in your teeth in between your appointments  if you don't floss daily.

Speak to your general dentist or dental hygienist  about suggestions  to improve  your home care.

There are many great products on the market to help your teeth and gums stay healthy so that you can have great orthodontic success. 

Clear Correct  does send their aligners in batches.
If you are unsatisfied  with your progress  your dentist should  be able to submit a revision  at no additional  charge.

The aligner  buttons shouldn't be visable in your wedding  photos  if the  composite shade was matched properly.

I would call your dentist and ask for their suggestion. They may prefer you save the band if it is salvegable. 

Both would work. Damon clear will still have the same discomfort as traditional braces and food restrictions.
If you feel you would be complaint and wear your aligners every day, Invisalign is an easy choice.
