Has anyone used any of the online tooth straightening aligners? I had Invisalign ten years ago, my helpful dentist didn't tell me I would need to permanently wear the last set as maintenance, so I binned them, and naturally a lot of my teeth have slipped back. That was £4k back then.
There are now a load of companies online that do the same thing, remotely, ie you take the impressions yourself and they produce the resulting aligners you need.
Has anyone actually used any of them? Of course some will be scams, it's the nature of the beast, but some must be legit and provide a good service? Any experience with the one to use, or indeed one to avoid would be gratefully received.
