This Stuff Works
I'm a heavy coffee drinker, former smoker and I drink lots of soda. All bad for your teeth. I have tried these types of products before but never one that you paint on with a brush. I've tried the strips, they don't work. The gel and the trays nope.  But this stuff works!! Its simple to use. You open the pen, give a few twists until some of the gel comes out onto the brush and you are in business! Paint it on and leave it per the instructions and you get whiter teeth. So simple! I've used this product now for 3 days, twice each day. After only 3 days my teeth are several shades whiter. I am so happy with this product and will not hesitate to buy it again!
