Either polishes you laboriously teeth cope, so you can use them individually (with little thermoplastic) or you can take a little more thermoplastic and sets the teeth on it unprocessed. Because of course does not look quite as professionally, when you look through the thermoplastic, but if you let it run according to the back or puts it on the inside and disruptive simply cuts away or polishes, then there is still a great result and holds great. The taste is at first always something disgusting or not so tasty, but that passes quickly. And so annoying it's not. Thus 2 hours or more is possible.
Talking also goes quite well. The beautiful is, you just have to get it right once and it stays that way. One can use the braces and teeth like a take out again without any problems.
I'm excited. Did I just got a second pair. ^^
