It works!
I just can't believe that this makes true magic when it comes to whitening teeth.  I could tell a difference and I don't smoke nor drink coffee but wow what a difference on my husband.  He used it three or four nights in a row brushing two minutes, per instructions, and it is amazing stuff.  I highly recommend following the directions to the T, because I was so excited I opened it and made a mess, but if you're careful and use the dark towel by the sink as recommended you'll be fine.  Even when it splatter everywhere, as I said I didn't read the directions to spit out as close to drain as possible, because it is natural it was a breeze to clean up with a wet cloth.  Make sure you floss after use because I cleaned my gums and black residue was still in gums even after brushing so just FYI.  I can honestly say conservatively speaking, this little jar will last me and my husband using once a week for at least a year, you don't need a lot.  Comparing the price of whitening treatments and how painful they're (if sensitive teeth) this is a no brainer, I didnt feel any difference on my teeth, sensitivity wise, at all.  Love will recommend to friends.
