Do those teeth whiteners (such as crest whitening strips) work well?

Question

Do they also cause sensitivity?

Answer 1

I personally love them but i've heard other people disagree... and they didn't make my teeth sensitive but every person is different.

Answer 2

The Crest ones made my teeth really sensitive and the results were actually not that great!  The one I use now is from http://mycelebsmile.com/y/ online and it had been absolutely great for me so far.  No more Whitestrips for me, hehehe!

Answer 3

According to their claim yes they can whiten your teeth but lot of people has been complaining because of poor results. if you really want to have a pearly white teeth, go to a certain person that have more knowledge on how to whiten it even for an hour.
