I have an overbite and my two front teeth have always been at a slight angle. So, I invested in invisalign a few months ago, I have had them in for about two and a half months.
The first month was miserable! But once I got used to them, now I feel weird if they're not in. So far, I'd say they are defiantly worth it. I can physically see my teeth moving already and its only about eleven months long, faster than braces, its pricy, but I recommend to go for it.
