Teeth Clenching and Braces

[UmbrellaFish]

This is (maybe) the most off-topic topic I've ever posted, but here goes!

So, I've had braces for about three years and I've been wearing rubber bands to fix an overbite for one and a half. The overbite still isn't fixed and I found out today while doing some research that I clench my teeth.

Anybody who's had braces, or clenches their teeth (or both!), have any advice? I'd like to get my braces off as soon as possible, and I'd also like to eradicate this clenching problem (I intend to pick up some mouth gear soon).
