Verdict - Day One

Well, that was just nasty. The instructions say that I should contact a poison control center if I ever injest the "Mentadent Tooth Whitening System". Because I don't want to have a medical emergency at work, I decided to try and not swallow for the designated 10-15 minutes. Ew. I felt like I was going to drool all over myself. It's disgusting. I won't go into detail. I give this product a "D-" so far but I'll continue to use it for a week to see if there's any whitening improvement...
