Do Crest Whitestrips really work that well?

Question

Are they as good as everyone says or is it yet another teeth whitening gimmick to lose money from?. I'd love to know if they worked for you.

Thanks

Answer 1

They do work but are not as effective or last as long as night bleaching carried out with the dentist

Answer 2

Yes they work great, i smoke and drink coffee and a month before my wedding i used them and all my pics are really white teeth.. yes they work

Answer 3

My mom tried them one time and they seemed like they worked pretty well, especially for the price. I have to warn you, that it will probably make your teeth sensitive. I think it's still worth giving a try.

Answer 4

I just came across your question and I already have a good base color but they whiten your teeth 2 to 4 shades. I use them 3 times a week for a few weeks before big events. But just keep in mind,If your teeth are sensitive, it might irritate them.
