Same product the dentist sells . . . for a whole lot less!
Love this product.  Use it with my existing bleaching trays once or twice a year and the results are great.  This version of the 22% bleach is much less sensitizing than the last batch I bought a year or so ago.  I've used this product at this strength for at least 10 years and have no plans to try anything else!
