Crest 3D Whitestrips Luxe, Supreme FlexFit 28 Strips

[This review was collected as part of a promotion.] Love these whitening strips! My teeth definitely looked whiter after only 7 days! The packaging is nice and I love the value! The only thing for me was that my teeth were really sensitive after I used them. I had to use sensodyne toothpaste after. Other than that, they are amazing!

[This review was collected as part of a promotion.] I have not used crest whitening strips in years. They have definitely improved. I love these strips. They're easy to apply, just peel the strips off the plastic and place onto teeth. You leave them on for an hour and then peel off. I love that they stay in place the whole time. I noticed that my teeth looked whiter after just a couple uses. Crest is my definite go to for dental needs.

[This review was collected as part of a promotion.] I could tell a difference within the first couple of times using the strips on my teeth. I didn't experience any pain at all while the strips were on my teeth. I have in the past had pain from other whitening strips, so I was very cautious when trying these. The strips are easy to use - you just peel, stick to top and bottom teeth, and wait for the results. They fit well, are comfortable for the most part, and are mess-free. The gel on them tasted a little minty but wasn't too awful. I will purchase these again a couple of times a few times a year, as I do drink a few cups of coffee and tea most every day. I do pair this with the Crest 3D White toothpaste, which I feel helps the process in between.

[This review was collected as part of a promotion.] I received this product for free in exchange for my honest review and opinion. So I have used crest whitening strips before, but I feel like these worked deeper into whitening than their regular ones. I was worried about teeth sensitivity but just follow the instructions and you shouldn't have to worry about it too much. I definitely recommend this to anyone looking for a brighter smile!

[This review was collected as part of a promotion.] I recently tried the Crest 3D Whitestrips Age Renew, which promises to reverse years of staining and brighten teeth up to 25 levels. The kit includes 21 treatments (each with upper and lower strips) and is designed to fight age-related yellowing for a naturally radiant, younger-looking smile. While the product aims to provide a professional-grade whitening experience at home, I found the application process somewhat challenging. The strips require completely dry teeth to adhere properly, at least, it did for me, which can be difficult to achieve. Even then, they tended to slide around during use. I used the treatments every day, and did notice a visible improvement in the whiteness of my teeth. However, despite claims of being enamel-safe and designed for aging teeth, I experienced slight sensitivity after use. Overall, the Crest 3D Whitestrips Age Renew offers a convenient at-home whitening solution with noticeable results. However, the application issues and minor sensitivity I experienced may deter me from repurchasing this particular product.
