I missed the opportunity to get my teeth professionally whitened a while back, and I'm regretting it. I can't get myself to drop precious dough on the whitening strips, though. Does anyone know of more affordable ways to go about this? I know it's a bit silly to even care about such a thing, but I figured I'd ask the pros.

It's a bit silly to care too much about, I know, but I thought I'd just ask Incase anyone has had success in a pinch.

Thanks!
