Arm & Hammer Whitening Booster Review

I've tried this plus a couple of other whiters.  They work ok but what they don't tell you is that your teeth become very sensitive afterwards.  I know you probably said I did it too much but I did them a year a part.  If you want your teeth whiter, go to the dentist and pay the extra money.  It's worth the price because of your teeth being too sensitive for a very long time afterwards.  I do not work for a dentist.
