I don't have braces, but I have a gap in the front between my top teeth, and I've always wanted to look into getting it fixed. I don't want traditional metal braces however, so I was wondering;

-Do the invisible braces really work?
-How do they work?
-Can they be removed during the day?
-How much are they?
-Are they as painful to wear as metal braces?

Thanks in advance for anything you guys can help me with,
