Review (5/5): Perfection in a strip.
I'm in my first week of using the strips and already I'm noticing a significant difference in the color of my teeth. I'm not getting any 'spots' which I was nervous about obtaining, but an all-over whitening causing only a slight sensitivity if I put the strip too over my gums, but otherwise no need for a specialized toothpaste for sensitivity. The strips are very easy to use and not uncomfortable at all. I can talk perfectly fine and my family doesn't know when I have them in or not, even on the upper teeth. The only not-so-fun part is taking off the strip...when you take it off the gel is still on your teeth and you either have to use kleenex to remove it or brush your teeth quickly because it does taste nasty. The strips do have an acid in them which I've heard can eat away the teeth, but I have never heard of the whitestrips causing this, and I'm sure there would be more notice from the public if it did. I have a bar behind my lower teeth since I had braces last year, and the whitestrips work fine over them...although it is suggested not to use the strips while there is any dental work such as braces in your mouth. Overall, this product is awesome...works like a charm!
