I really like this product. I drink a lot of coffee and I love red wine both of which can cause teeth staining. I use these strips 3 times per week and I get great comments on my smile, especially in photographs. I've gotten my daughter and fiance to use these too.

I bought a pack of this last year and used it once a week for 4 weeks and people starting noticing my whiter brighter smile! I stopped using it for awhile because I didn't want to over whiten my teeth. People love comparing their teeth to mine. I now use one once every 3 months.

What is the first thing people notice? Your skin and your teeth. If yoiu want to make the best impression ever then get your teeth super white with Crest White Strips. I use Professional Effects and they are life changing. My teeth are beautiful and I owe it all the Crest, thank you! Super easy to use, fast and no mess.

I started using the whitestrips a few months back and loved the results. Everyone noticed the difference and gave me compliments all the time. I did have sensitivity but just went from using everyday to every other day to once a week. Once my teeth were as white as I liked it was fine to only use them once a week to maintain. My sister was a bit jealous of my results since we were always known as twins even though we are a few years apart we look so much alike. Our teeth on the other hand were now very different. I gave her just three strips to use and now she has purchased her first box. We are now both lifetime costumers. Thank you so much Crest for a great product!

[This review was collected as part of a promotion.] These whitening strips are easy to use and effective. I see a huge difference in the color of my teeth just after one application. However, I don’t like how sensitive my teeth feel after use for at least a good 24 hours.

I have used Crest whitening strips for many years and I must tell you, they are the only strips that work really well as compared to the other brands out there. Also, they are a lot less expensive than the whitening procedures at a dental office. I always recommend these to my friends and family to use.

[This review was collected as part of a promotion.] I really liked this product overall—it’s easy to apply and stays securely in place, which made it super convenient to use. However, if you have sensitive teeth like I do, be cautious. I already struggle with cold sensitivity, and unfortunately, these strips amplified it quite a bit. I wasn’t able to complete the full seven-day treatment, so I didn’t experience the full whitening results. But for those without sensitivity issues, I imagine this could be a great option. These strips are super easy to apply and surprisingly secure—as long as your teeth are dry when you put them on. That small step makes a big difference! Once they’re in place, they stay put really well without slipping or shifting, which makes the process feel effortless.

I have lightly pale yellow stained teeth from drinking soda as kid as well as braces. I have tried whitestrips in the past and got frustrated that they didn't stay on your teeth. I am 1 week into the treatment and while I cant say I have had amazing results I feel like I can see a small difference. They have greatly improved the strips so they stick well on your teeth. I am hoping once I am done with the whole package I will have bright white teeth. Fingers crossed!

I bought Crest's Professional Effects Whitestrips to brighten my smile before my wedding day because I had accumulated some brown coffee stains around my front teeth. I did three days of the whitestrips and was very pleased with the results! I would recommend these whitestrips to anyone wanting to get rid of stains and brighten their smile a few shades whiter.

[This review was collected as part of a promotion.] Definitely seen a color difference on my teeth during the first week of use. I don’t like that I had to leave them on for an hour. Felt like it was too long, didn’t feel them on my teeth but I did feel sensitivity on my teeth after using them because I use sensitive toothpaste. Love how my teeth looked after using them. If you can stand the sensitivity I would definitely recommend
