Bests & Worsts Reviews from Amazon

My teeth have a light grey tint naturally, now they are a much browner deeper gray afternusing this stuff. I thought it looked like they were getting brownish within days of using The Dirt but stuck with the tooth powder because others said it took a while for their teeth to get whiter. I even ordered a second jar for my husband thinking that suddenly my teeth would turn white and he would want to use it too. But after about 4 weeks I realized my teeth had become brownish gray, not white. It is not superficial - the discoloration is in the teeth - I'm so embarrassed my smile now looks like I have shadowy brown teeth and I don't know what to do.
