With professional tray bleaching systems, their effectiveness is excellent in an overall teeth whitening review and is comfortable and easy to use. This treatment can change the color of your teeth 11 shades whiter. The boil and bite tray bleaching systems are also good to use and deliver a results of nine shades of brightness.

There is something call a dental whitening click pen that I’ve never heard of before that can reduce the discoloring of your teeth and give you a smile eight shades lighter. But when you start getting down into the non-moldable trays, and the whitening strips, sprays, and toothpaste, you are wasting your time. Though these products may be easy to apply, one teeth whitener review suggests that they show very poor productivity.
