Crest 3D Whitestrips, 1 Hour Express, Teeth Whitening Strip Kit, 20 Strips (10 Count Pack)

I use these as a quick way to whiten my teeth since they are already naturally pretty white. These give noticeable results and work amazing for the price. I would suggest some of the other Crest Whitening Strips for more dramatic results.

These Crest 3D Whitestrips worked really well. They’re easy to use, stay in place, and I noticed a visible difference in just a few uses. A simple, effective way to whiten at home!

Absolutely my favorite go to when you need a whiter smile. I haven’t found a better product and I’ve purchased whitening trays from my dentist. The Crest White strips outperforms the prescription trays with me.

Okay here's the deal - I had a photo shoot in two days and forgot to schedule in a dental whitening appointment. So here I am with $150 worth of teeth whitening products and a prayer. First let me say: A) I've never used any teeth whitening products before B) I've never noticed sensitivity in my teeth before So I went to two stores and grabbed everything that reviewers before said I might need. Products that I used: Crest 3D White 1-Hour Express, 1 Crest 5-Minute Touch Up Kit, 1 Listerine Healthy White Mouthrinse, 1 Bottle of Hydrogen Peroxide, 1 Sensodyne Fresh Mint, and a pack of flossers Note, I got the 5-Min TouchUp for the day of photoshoot and the non-whitening Sensodyne because I just wanted it for the potential pain. Before I even started the strips I popped two Advils for potential pain because I'm a wuss. There are two strips in each treatment packet. A smaller strip for your lower teeth and a longer strip for your upper teeth. Neither strip is long enough to reach ALL of the teeth on either set which I found weird. I guess my teeth in the front will be white and who cares about the rest is the thinking? Anyway, carefully put the strips on and try to avoid touching your gumline, even the portions that just dip into the crevices of your teeth. As soon as the strips on you feel them working. For me personally, I'd compare it to the tingling sensation I got from mouth wash gargling. As soon as each layer was on I used my fingernail to push the strips tightly into the crevices between my teeth in order to get even distribution of the whitening effect and then I sat back and waited for an hour as it did its thing. I didn't notice any pain in my teeth or gums immediately but it felt weird because I wasn't quite sure where to place my tongue - I didn't want it to get burned or singed after all so I spent the hour with a rapidly drying throat and open mouth. 1st Treatment: No pain, no sensitivity issues, no noticeable difference in teeth color 2nd Treatment: I was braver, so I brushed my teeth 5 minutes before and gargled/flossed right after. I noticed that my teeth seemed a good deal brighter this time before starting (maybe lighting) however I also noticed a concentration of stains closer to my molars so I worked to get the strips near those this time. 3rd Treatment: Started to notice a little bit of sensitivity. Only along one or two teeth and near the gumline. Nothing major. 4th Treatment: I accidentally licked the lower strip while repositioning, other than tingling no sensitivity issues. OVERALL REVIEW: It worked. My teeth are at least 2-3 shades brighter. I think long-term I could make them the perfect shade of white. I will note that I wouldn't use the Crest 5-Minute Touch Up as anything more than just a small patch - the strips are much smaller and more flimsy and of course the impact is less. Regimen: 4 treatments = one set of strips every 12 hours. Post-treatment I waited one hour and then lightly brushed with Sensodyne and Listerine. In mornings I gargled with Hydrogen Peroxide. P.S. - I don't know why reviewers of this product are leaving it on for 1.5-2 hours. It clearly says 1 hour on the box. P.S.S. - These are super cheap on Amazon. $21?! I paid $54 at the place that rhymes with BandAid.

Workes all the time, good quantity for the money

Very good product and the seller has a nice quantity for the money. The packaging could be better as my box was destroyed, but the items was not hurt at all. The best deal I have found so far on the Internet is the seller. Very good product.

Love this brand for whitening strips. Works super well and quickly too. I started using these and people started commenting on how white my teeth are.

These dont white my teeth much like the other crest strips and leaves a film on my teeth the others no not.
