[This review was collected as part of a promotion.] I am very impressed with the results so far from the Crest Whitening Pen plus Light. I drink coffee everyday so I do have the coffee staining on my teeth. This product gives me hope that I will have better looking teeth. After just a week I noticed a difference. I like this way better than uncomfortable strips. Or gels that hurt my teeth. I will repurchase this so I can stay ahead of future stains as well!

My review is one star because for the crest whitening gel has not been effective for me. I tried all whitening factors, but still yellow are my teeth. I usually drink tea, but I stopped for awhile, just to see any results on my teeth. I very disappointed. I wanted to save money, so possibly I'll give the dentist a try..

[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.] 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.] Whenever I just want a little extra boost of confidence, I look to the crest whitening pen and LED light to give my smile a bit more love for the day. I apply the gel to my teeth, wait 30 minutes before I eat and if I feel like putting a boost to my smile hours later, I use the LED light for even better results. My teeth look amazing. Thanks, Crest 🫶🏽

[This review was collected as part of a promotion.] I recently tried the Crest 3D White Whitening Pen, and I’m pretty impressed with the results. The application is super easy with the twist mechanism, and the gel goes on smoothly. After using it for about a week, I noticed my teeth were visibly whiter, with less staining. It’s a great option for a quick touch-up, especially for areas that are harder to reach with traditional strips.

[This review was collected as part of a promotion.] The Crest 3D White Whitening Pen with Light erases surface stains and is similar to what dentists use. The pen allows easy precision application and the light helps boost the stain fighting gel. Plus it's safe for your enamel. I used this for week after breakfast. I brushed my teeth first than applied the gel. The first time I had to twist the bottom about 10 full times to get the product to start coming out. I used the included light which took about 5 minutes and then waited 30 minutes before eating or drinking. The gel feels and tastes similar to a fluoride treatment at the dentist. I’m definitely seeing a brighter whiter smile. The minty flavor did mildly upset my sensitive stomach .

[This review was collected as part of a promotion.] I had thought this only came with the whitening pen, but it came with a light boosters which was very nice. It didn’t have an odd taste in my mouth like the strips do which was nice and overall, I can see my teeth whitening happening which I usually can never tell with the strips or so!

[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 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!
