It does whiten your teeth. But I can only use it a couple time a week or a few time a month due to sensitivity.

OUCH!
I thought this would be something good to try but the pain is unbearable! Feels alright when you first put them on but the minute you tip your head back or even move your head the pain is so intense your ripping them off your teeth. They also don't stay in place well at all!
