iWhite Teeth Whitening Kit Features

This is what you get with the kit iWhite :

And that is. He uses two trays per treatment, one for the upper teeth and one for the lower teeth, which means five treatments in total.

There is no doubt that iWhite teeth whitening kits are easy to use. Its fixed-form mouth trays require no shaping, no LED light to worry about, and pre-measured gels mean there should be no room for error.
It holds the trays for 20 minutes per treatment, which is not a huge drawback. You won't be able to talk much with layups inside and you may find yourself dribbling a lot, but the same goes for most other layup-based kits.
