Crest Whitestrips - Classic 14 day or Premium 7 day??!
Question: As a new user, which one is better for me to start with? I wanted the 7 day, as I cant be bothered with doing it for 2 weeks! Does the Premium version burn your gums more as it contains more peroxide? Please tell me your opinions.

Premium work better. They don't burn your gums but they did make my teeth more sensitive when i had them on.
deff 7 day.
I used the 14 day and it took SO LONG. But then again, i couldn't really finish because I was starting to look like a toothpaste ad already. It lasted for about a year, though, like it was supposed to. They didn't hurt my teeth at all but the second time around they did.
use the classic, slow could be better
