I never write reviews but I had to for this. I have been using my first pack for 4 days now and I can see a huge difference. I was really worried about the sensitivity because I have very very sensitive teeth, but I just had very slight sensitivity in one tooth for the first 2 days and now nothing. This product really works. My only downside is with crest as a whole... they said you get 10% off when you sign up with your email, however when I got the code and entered it, it said it wasn't valid.

I swear by these! Every time I have used as directed, someone has pointed out how white my teeth look (I generally used about 2-3 a year.) I get minor tooth sensitivity, but the results are well worth it and it doesn't last very long. I have tried store brand versions, but I feel like I get the best results with these.

[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.

The Crest 3D whitening kit is a must have for anyone who is dedicated to their teeth and oral care and wants their smile to look absolutely stunning. If you are looking to enhance your beautiful smile, look no further than this incredible product that will do just that and more

I have used these for years and always get compliments on my smile. I was worried about damaging my teeth with these, but my dentist and oral surgeon friends assured me these were enamel safe. To avoid him sensitivity with these, be sure to swish with lukewarm water really well after removing the strips, so you don't leave the irritating gel on your gums. I used these several times in high school first, and now (in my 20s) I buy a box once a year and I use them year-round to touch-up before interviews, dates, holidays, weddings, etc.

Before any event or special occasion I will use these for about a week and I can tell a huge difference in the whiteness of my teeth. They can tend to hurt my gums a bit because my teeth are so sensitive but other than that these are amazing for the price

I just recently started using these and I've only done it a couple of times but I haven't had any problems with it. I haven't seen any clear results but I'm giving it some time to work. Overall, it seems like a decent product but clear results aren't quick.

I love the idea of having beautiful white teeth and this product helps. Sometimes I struggle to dry my teeth off enough to get it to stick which can be frustrating; but overall I see a difference when using this product consistently based on manufacturers directions!

Hello my name is Brittney and i would like to say these whitening strips are remarkable i was worried because i don't trust bleaching as far as dental bleaching but i was amazed how these whitening strips work happy to say that my smile is a non stop in the streets and i love looking at them will definitely be keeping my smile up. Thank you, Brittney

Crest come together with all other toothpaste products, but is 100x better. Since Crest had their 3D Whitestrips, I've always wanted to try it, and my mom got it for my friend and me and we tried it at the same time and it works, but after that I wasn't able to get some; but the point is you should really try Crest 3D Whitestrips, it work guaranteed to give you what you expect!
