Why you would have proper braces i have no idea, i feel pretty sorry for people when i see them because it must be awful
i have had invisalign for a year, and its just like part of your daily routine after a while and the results have been great, i don't even wear them 22 hours a day, just when i can which usually ends up about 20 hours a day, even my orthodontist has been impressed with the results, and you can use them to whiten your teeth, i don't exactly feel like a new person but i feel a lot more confident about my teeth now.
Some people have had problems with them creating cavities because essentially your trapping sugar against your teeth which results in exponential decay, but i have been pretty strict in only drinking water with them in and brushing before putting them back and no problems, teeth have never felt healthier due all the extra brushing.
I tried drinking the odd thing with them in when i first got them and it just felt awful, but some people apparently drink coffee etc with them in, i don't think i could do it myself.
I have to have refinements now for 20 weeks which i didn't have to have to correct my bite (called distillation apparently?) and although i am skeptical about using them to move back teeth i don't feel like there such a burden on my life than i am desperate to get rid of them.. could have been done in another 10 weeks as there are only some movements on my bottom teeth left..
