It is hard to find any unbiased research results and any independent findings on which teeth whitening products work best and how effective they are.
Every company producing or selling celebrity teeth whitening products definitely claim theirs to be the best teeth whitener. But which one is most suitable teeth whitening product? There are strips, gel, laser whitening, toothpaste and even home remedy for teeth whitening.
So, there is no serious study on which product works best. With the current fad of getting celebrity white teeth, it is hard to pick and choose the right one. Best is to ask a dentist you trust for recommendation.
maybe you can wikipedia it, thats a tuff one, as all these site are avertiser driven so I wish you luck! I personally use sonicare toothbrush and hydrogen peroxide for my whitening and cleaning …nothing is better in my opinion!
Maybe this will help-
