Teeth Whitening Gel : Surface stains only

I tried this product out for a week, twice a day. I would apply this on a dry toothbrush, as the instructions say, with an equal amount of GoSmile's luxury toothpaste. This definitely made my teeth brighter not whiter. I noticed that my teeth would be less yellow after brushing than before but after a week, my teeth definitely did not get white. Granted I have years of stains from my old diet of coffee and soda. But the results I got after a week could have been easily and quickly achieved with one white strip. That being said, it did not irritate my sensitive teeth and it seems more effective than "whitening" toothpastes from a drugstore. I would get this if you are scared of white strips and have patience.

I received this product for free for testing.
