[This review was collected as part of a promotion.] This is a great way to brighten teeth at home! I’ve been looking for a way to get whiter teeth and this worked so well for me! My teeth can be sensitive, but I followed the directions and this didn’t cause any sensitivity at all for me.

[This review was collected as part of a promotion.] I thought this product was a pretty good introduction in to the teeth whitening game. It was easy to use, and I think better results will be yielded with prolonged use. I thought it was packaged well, and I didn’t find it to bother me teeth. Good job Crest.

[This review was collected as part of a promotion.] This whitening pen is a game changer! It’s super easy to use, with a sleek and compact design that makes it perfect for travel or quick touch-ups. I noticed a visible difference in just a few days—my teeth looked brighter without any sensitivity. The flavor is mild and fresh, not overly minty or chemical-tasting. I also love that the ingredients are gentle on enamel and gums. It dries quickly and doesn’t mess with my daily routine. For the price and how long it lasts (up to 70 uses), it’s absolutely worth it!

[This review was collected as part of a promotion.] The pen uses a small brush tip for precise gel application, which you leave on teeth for 30 minutes before “boosting” effects with the included LED light device. The device goes into the mouth and is easy to hold (and not heavy), and turns itself off automatically after the recommended treatment time. The gel is meant to brighten and reduce stains, and it did a decent job of lifting my coffee stains and lightening my teeth about one level. If used regularly, I suspect it would help maintain tooth brightness, but I don’t think it’s really going to affect long-term staining or changes in color like an office visit can. The process is easy and clean, though.

[This review was collected as part of a promotion.] The Crest Whitening Pen & Lightis a convenient, at-home teeth whiteningsolution. The pen applies a gel that sticks to teeth, while the blue light helps accelerate whitening. It’s easy to use and great for targeting stains but results vary, and it may take multiple uses for noticeable whitening. Overall, a handy option for touch-ups but not as strong as professional treatments.

[This review was collected as part of a promotion.] Having used the Crest 3DWhite Easy-to-Use Teeth Whitening Pen + Light, I can confidently say it’s a game-changer for achieving a brighter smile. The pen's precision applicator makes targeting specific teeth quick and mess-free. Paired with the light, the whitening process feels efficient and effective, with noticeable results after just a few uses. The gentle formula doesn't cause discomfort, even on sensitive teeth, and it easily fits into my routine. Compact and portable, it's perfect for touch-ups on the go. Highly recommended for its convenience, comfort, and impressive results

[This review was collected as part of a promotion.] I love the twist feature as that's easy to use, but the brush pen isn't easy to keep the product ONLY on your teeth. doesn't have a good taste at all! Burned for me actually. It really does whiten your teeth tho!

[This review was collected as part of a promotion.] So, I was able to grab this product for free. And when it came in the mail, I thought that I was just getting the whiting pen. While it came with the pen and the mouthpiece. So far, I absolutely love it.

[This review was collected as part of a promotion.] I have found a great whitening treatment that works really well. I drink a lot of coffee and black tea, which has made my teeth very dark and brown. This treatment set is not only effective but also easy to use. I can take it with me and use it anywhere, without the hassle of carrying too much stuff. Plus, the price is quite reasonable. I highly recommend it!

[This review was collected as part of a promotion.] This isn’t a game changer but it is a good product. The pen can be a little finicky in terms of product dispersement, and keeping your lips away from teeth while product sets can be interesting. I didn’t have any sensitivity which is great for me, but I didn’t notice dramatic results. 2x a day for 2 weeks would probably be more effective? I don’t think that’s doable for a lot of people. Good for purse size though!
