Just randomly I looked back at the end of the board, and found this thread from 2004, when the forum was barely a year old.
Some of the predictions are indeed true, with "fashion braces" in some South-East Asian countries being a"thing", and also tooth art, with various things you can stick to your teeth. We perhaps didn't think of TADs, or how widespread cosmetic treatment would become. Impressions are a thing of the past in some places, with a 3D scanner now doing the job.
So here's a thought? What do we realisticaly think might be the case in 2036? I'm sure deep down we'll all like to think that "what goes around, comes around" and we'll be back to full bands and headgear, but what might be "plausible"... might our predictions be as correct as they were then?
