[This review was collected as part of a promotion.] I have been testing this product and I have realized that it works! It whitens my teeth gradually and I already see the results, and also its flavor is not as strong as other products I have used before

[This review was collected as part of a promotion.] I really wanted to love this little whitening pen because it takes 60 seconds and is as small as a mascara tube so it is easy to grab and go. The main problem is the applicator, it is a twist to release mechanism on a brush so especially with the first application, it takes so many twists to start seeing the product then all of a sudden it is seeping out and you have wasted it (see photo). Also the brush gets pretty gross after a single use and if you want to wash it, you will lose the extra product left over on the brush. It is also a twice a day application which is hard to keep up with, but if you only have to leave it on for 60 seconds it makes it more manageable. I think they are on the right track, but not quite there with this whitening pen. With improvements in the applicator, I think it would be a much more appealing option for whitening

[This review was collected as part of a promotion.] It came in good condition, I have used it once so far. I like it. It's easy to handle and support, giving the same flavor as a regular toothpaste. I just have to keep on using it to see any results.

[This review was collected as part of a promotion.] This Crest Whitening Pin is fantastic!! I noticed my teeth were whiter after ONE application! The first photo is before, second is after! I would highly recommend this product & I would definitely purchase it myself! It's very easy to use and perfect to throw in a purse or bag for on the go!

[This review was collected as part of a promotion.] I liked that the pen was easy to apply and no real mess. It’s kinda awkward to keep your lips away from your teeth while it drys, but that step only takes about a minute. I only gave this 3 stars because I didn’t notice a big change in color, but I think this product would be great for upkeep after using a stronger teeth whitening product initially. I didn’t have any sensitivity, and as long as you don’t apply too much product, there’s no real taste to it which is also a plus. Overall the pen would be a great product for travel and maintaining a whiter smile after using the Crest Whitening Strips first for the biggest color change difference.

I had high hopes for the Crest 3DWhite Easy-to-Use Teeth Whitening Pen, but it turned out to be a letdown. After using it consistently for a week, I saw little to no difference in the whiteness of my teeth, which was quite disappointing given the brand's reputation. The twist mechanism is inconsistent, making it difficult to dispense the right amount of gel, and the brush tip tends to create a messy application. The gel itself has a thick texture and an unpleasant taste, which made the entire process uncomfortable. Overall, it didn't meet my expectations, and I wouldn't recommend it if you're looking for a quick and effective whitening solution. There are other products out there that deliver better results with less hassle.

I typically use the Crest Strips but I keep this one with me when I travel or just on the go as I'm a coffee drinker. It's a tad pricey for what it is but I try to avoid teeth discoloration so I tried it out. I don't think I'd buy again but that's just because I often forget to use it.

The Crest 3D White Pen is a great product for quick, on-the-go teeth whitening! It's easy to apply and doesn't leave a strong aftertaste, which I appreciate. After consistent use, I did notice my teeth looked a bit brighter, which is exactly what I was hoping for. However, the results aren't as long-lasting as I'd like, so I find myself needing to reapply often. It's a good solution if you need a quick boost in brightness, but for long-term whitening, there might be other options. Overall, very good for short-term use!

I use this pen before I put on my night guard (to keep me from grinding my teeth) I wake up with whiter teeth. I am not convinced it's different than any other whitening pen but it works well with night guard. If you have sensitive gums it might be too harsh.
