I just bought the strips and have already noticed a huge improvement.. I am so glad that I choose Crest for my teeth and the best results.

I have now tried 2 packs of this product and it only worked a little. Maybe about 50 % of the claims. May due to the fact I am 73 years old?

CANT go wrong with the strips! Try your own to believe and realize they truly work! Thank you, Crest!!!

Ive used a dozen kinds of whitenings trips n pastes & these Professional Effects from Crest are FAR & ABOVE all the others I've tried!

This has helped me a lot, better than going to the destinst. It does not hurt and it's easier to do it without any appointment.

I love these strips! You can start to see results the first time you use them and they will look great at least the 3rd day

I received these and have done four treatments. Out of the four treatments, two of them did not stick to my teeth and one pair had holes in them!!!

I noticed whiter teeth after just one use. I am excited to have pearl white teeth again!! Highly recommend these!!

Amazing! First use I already see the difference.I recommend this to everyone that been wanting to have a whiter teeth.

Love them! Really work. People comment on how white your teeth are! Best product out there! I highly recommend.
