This is a new teeth whitening tray kit that hit the shelves a few weeks ago. The package includes a whitening gel made of Peroxide Bleach, an innocuous compound that's commonly used by dentists. It also comes with a pair of custom mouth trays and a whitening light very similar to those used by the professionals.

The usage is very simple, just try any of the mouth trays to see which one easily fits in your mouth, then take it out and pour some hot water in it so it can become malleable. When that part is done just put the tray in your mouth and bite a couple of times until the shape of your teeth are carved into the tray. After that just take it out and let it cool down for a while so that it becomes harder and retains the shape of your teeth permanently. Now just apply the whitening gel in the tray and put it in your mouth, then get the whitening light, switch it on and point it at your trays for a couple of minutes. That's all there is to it, really easy.

The results are truly impressive, my son tested it and we took a couple of pictures to see the difference, you can take a look at them at my website. Now it looks several shades whiter. To conclude this teeth whitening tray kit review I must say that it impressed me a lot, this kit it's the best one i've tried so far.
