I had Invisalign for about a year and while uncomfortable at first you do get used to them. Here's a tip though, don't cut your nails too short because once I did that and with no nails it was difficult for a couple days getting the trays off. Very worth it, I can't stop smiling and many have complimented me on my teeth and smile. Best decision I have ever made for me teeth! Couldn't be happier!
