For years I tired to find the product for helping my teeth shine. I was afraid to smile but now it's like having a whole new mouth.

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?

This product has been the best whitening product that I have used in terms of results and sensitivity. Highly recommended.

Easy to use.. can do anything while whitening.. I clean while I whiten then I check off two things at one... Clean house with white teeth

I could definitely see results with this product. And pretty quickly. I will use the Professional Effects whitestrips again.

one use and it feels like a dentist is drilling my teeth no pain meds this is by far the worst experience i’ve ever had with whitening strips

I used the strips only 6 times snd my teeth are noticeably whiter. Easy to use snd great results! And the online prices are great!

Good results, as expected with whitening strips. Visible results within few days of application ( as instructed ).

Here is a product that lives up to all the hype. Whitens your teeth and brightens your smile every time.

I decided to buy some Crest Whitestrips after not using any for 3-4 years. The results of the Professional Effects strips were amazing!!!
