Crest 3D White On-the-Go Teeth Whitening Pen - 0.13 fl oz

[This review was collected as part of a promotion.] Easy to use gel pen that paints on teeth effortlessly and doesn’t taste bad like some gels! The light fits comfortably in your mouth and was perfect to just sit back and relax while it does the work. Packaging was simple and to the point.

[This review was collected as part of a promotion.] The pen is a twist up pen so you can control the amount of product applied to the teeth. The easiest part of the process is keeping your mouth open for 60 seconds. Keeping an led light mouth guard in for half an hour is a little difficult. The product is not harsh. I think it would take several uses along with whitening toothpaste to see significant results. If you have a half hour to spare every day, this could be a great add on to dental hygiene.

I like the instructions that came with it

[This review was collected as part of a promotion.] I was honestly surprised by how well the Crest 3D White Pen and Light worked. It was easy to use and didn’t make a mess like some other whitening products I’ve tried. The pen goes on clean and the light is compact and simple to hold in place for a few minutes. After just a few uses, I started to notice a real difference. My teeth looked noticeably whiter and brighter. I didn’t experience any sensitivity, which I was worried about since that’s been an issue for me with strips and stronger treatments. It’s also nice that I can do this at home without needing a full whitening session at the dentist. It’s quick, convenient, and the results were better than I expected for something so simple. Definitely worth trying if you’re looking for a whitening option that’s easy to stick with.

[This review was collected as part of a promotion.] I was so happy to see how fast this tooth whitener pen worked. With just one application I started to see a difference. I added the light to make sure it cured properly and it was super easy just apply then in half hour put the light on it till it goes out.

[This review was collected as part of a promotion.] I love this product!! I have definitely seen a difference after a few weeks of using the product one a day. It will definitely take time to see true result but i can see my teeth are brighter and less yellow-y. Great product!!

[This review was collected as part of a promotion.] I received the crest 3D white easy to use application whitening pen & light applicator free in return for my honest. I find product to be easy to use, non irritating to gums and some whitening when used for some time as stated.

[This review was collected as part of a promotion.] Eh. The directions are conflicting. One place says an hour another says 30 mins. But the whitening goop won’t stay on for either length of time. The light only runs 10 mins so as soon as you close your mouth it rehydrates the goop and it’s gone.

[This review was collected as part of a promotion.] So easy to use, love the whitening pen and light duo. The strips are usually too strong for my sensitive teeth but this pen and light works wonders. 10/10 I really love how easy it is to use. Brush on and sit for 30 minutes before using the light. The light part is like 5-10 minutes, I always forget to keep track of time.

[This review was collected as part of a promotion.] I think this is soooooo much better than whitening strips. You just paint this on really quick, follow the protocol and then do a few minutes with the LED light! Super easy. I'd recommend this product.

[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.] After applying whitener for the first time, I could tell it already had improved the color of my teeth. I haven't been consistent with doing it frequently, but I like that the whitener isn't harsh on my gums and that the instructions say you can do it up to 4x a day. Not sure how much the enhancing light helps, but I would definitely recommend the pen applicator.

[This review was collected as part of a promotion.] I didn’t know I was getting the extra laser light with the teeth whitening stick! I have used them and they didn’t cause any sensitivity and works really well!

[This review was collected as part of a promotion.] I like this product! Its very easy to apply by twisting the applicator brush until the gel comes thru. You just brush on each tooth and doesnt have a terrible taste. The blue light is quick and easy to use

[This review was collected as part of a promotion.] I really enjoy using this product. It has easy to follow directions, and I found it easy to use. I feel it's a great value for your money because it is dentist level whitening without the high cost. The flavor was palatable and the ingredients are tolerated well by most people. The whole package comes with a whitening pen and timed booster light was a bonus. I found it whitened my teeth well even after the first application.

[This review was collected as part of a promotion.] I really enjoyed the Crest 3DW Pen with light. Super easy to use and the light application automatically goes off after 5 minutes which is super convenient. The liquid dries in about a minute. After only 2 weeks, my teeth looked stronger! I'll definitely purchase in the future.

[This review was collected as part of a promotion.] Crest 3D white pen with led light is very easy to use. Click the bottom of the pen for the gel to dispense. Then simply paint your teeth with the pen. After a half hour use the led light, which stays on for 5 minutes. Use twice a day. I did notice a slight difference in my teeth after 2 weeks, but I don’t see anymore difference after 4 weeks. The light died after 4 weeks, and you cannot replace the battery. They should make the light either rechargeable, or with replaceable batteries. I didn’t have any sensitivity or adverse affects. It has a light toothpaste flavor. Not overpowering. I had been wanting to try the pen for a long time, and wasn’t as impressed as I hoped I’d be. A friend did notice my teeth and mentioned they looked whiter.

[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.] I love how convenient the Crest 3DWhite Whitening Pen is! It’s compact, mess-free, and super easy to apply. I noticed a visible difference in the brightness of my teeth within just a few days. Perfect for on-the-go touch-ups or quick whitening before events. I highly recommend it for anyone looking for a simple yet effective whitening solution!

[This review was collected as part of a promotion.] One thing I really appreciated about this product is that it doesn’t taste like chemicals. I noticed a minor difference, I’m sure with more disciplined use it would be more effective. It did not leave a weird film on my teeth after either.
