text: will invisalign work for more serious cases of crooked teeth? it says it will on the website, but will it really? i had braces for a little over a year before but didn't wear a retainer and therefore three of my teeth are very crooked and misaligned now (the rest are ok). i want to do something about this now to get the problem fixed. i really don't want metal braces, they're just incredibley embarassing. will invisalign work for serious cases? i don't care about the duration, just as long as it works. let me know. i had a very minimal problem with my teeth when i got invisalign...the dentist told me i was a good candidate for it & we started the treatment & i paid $5000...  6 months later i was told i was done, told to use my last tray as a retainer (which was gross after liek 3 months)   when i had my invisalign off, by the end of the day, my gaps returned. now a year later, my teeth are just as they were before i started, i would not reccomend invisalign to anyone!
