I currently have them on my top teeth and it's really only to push one tooth into place. And I have ceramics on the bottom, because I had a tooth coming in sideways and invisalign definitely wouldn't have worked. The only reason I opted for the invisalign was because I really wasn't feeling going into college with a mouth full of metal.
It is a hassle taking it in and out when you eat, but I can only imagine it would be more of a hassle having nasty food stuck in your braces all the time. And you really do have to have that willpower to keep them in. It's not uncomfortable, but sometimes I just keep it out for hours and they feel tight when I put it back in. Whoopsie.
Did anyone else find it painful when you got a new set at first? It hurts me so bad I cry.
