This also seems to have whitened his teeth at the same time ;), typical "before, after".

But on a serious note, I had braces, after the were remove a wire was placed behind my teeth to keep them in place. It didn't stick to one of my ceramic teeth I had from an accident in my youth. The wire was removed and after some months my front two teeth were as far apart as ever. Ok, the overbite didn't return but things will move back at least to some degree over time.

As mentioned before, I myself would never just put any plastic material in my mouth with all the bad things known about plasticisers, bpa/bps, etc.

I've been using 30% Carbamide Peroxide whitening gel in the trays for about 30 minutes a day. So yes, they are whiter.

Could you share a link if it can be bought online?

I had braces at a young age and, like most people, have to wear a retainer at night to prevent our teeth from returning to their natural position. Did you?
