This product helped me so much. It really works, it made my teeth pearly white and I have gained my confidence. Using Crest 3D strips motivated me to not eat or drink anything that would damage and stain my teeth. I loved this product!

I thing that the Professional effects whitestrips are one of the best products out there. All the Whitestrips are somewhat sensitive to your teeth, but after a while you get used to it. Start out by using them only once a day---or every other day.

I LOVE these white strips. 1 use and my teeth are significantly whiter. I put them on while I do my makeup and remove them after and my teeth are nice and white! If you're looking for a simple one step whitening routine look no further

It all matters on how sensitive your teeth are. Mine aren't too sensitive so this works wonders. Makes your teeth into pearly whites in minutes. You can also get the off brand ones if these are too expensive for you, they literally work the same.

I love these white strips and I think they are very effective! I have used them with the 3D white tooth paste and mouth wash, and my results have lasted for months

I would give this the five stars if I had something to compare it to but I don't! They worked really well and I can see a good difference in my teeth! I've used this product multiple times and will continue to do so!

I love the results from these strips. I only use one a month though. My teeth will hurt for a few days after using these. My teeth stay at a B1 just by using these so they do an awesome job.

I think they did their job but I'm a triple threat to white teeth - I drink very dark black coffee, eat dark chocolate and drink the darkest of red wines. I think if I ate less staining food I'd see much better results.

Noticed an improvement in whitening after 2 applications. I have sensitive teeth and gums so I did have to space out applications more than what was suggested

This lightened the shade of my teeth considerably very quickly. Made my teeth very sensitive tho. I use them every other day and don't wear them as long as recommended.
