I take pride in my teeth, my sisters often say I am always looking in a mirror, not at my hair but at my teeth. I of course, use this with my regular dentist visits.
What's also great, I GET A LIFETIME SUPPLY of the tooth whitening pens. I can put one in my luggage, my purse, at work in my desk drawer.
Anyway, I took a chance on a product and it was GREAT!!!
