But, There is a bit of controversy in the dental community as to whether the "tooth whitener light activation" step actually contributes to the teeth whitening process.

Many recent studies by prominent dentists have shown that bleaching compounds contained in tooth whitening products seem to work well and give good results even without the use of lasers or lights. The use of lasers or lights had no effect on the results.

The study stated that the results were the same in both cases. The teeth on both sides were equally whitened in the initial comparisons as well as the evaluations that were made after one year of treatment.
