This did not whiten my teeth, I normally use the white strips which work great. I will not buy this again.

Better than average whitening product.
For the money it works well with many applications per pen. One of the best whitening products I've used.

I was enjoying the product but unfortunately my Boost light didn’t last me very long.

While we're happy you're enjoying your Crest 3D White Whitening Pen, we're sorry to hear that your LED light has stopped working, Timothy. You will likely have more applications of gel than light treatments, depending on how much and how often you use your Crest 3D White Whitening pen.

Great product
[This review was collected as part of a promotion.] My 14 year old decided he was using it. He loved it and we have already bought more. It actually helped whiten his teeth from where he had braces and you could see the little marks.

It actually works!
I used this whitening pen and the Crest 3D Whitening Deep Stain Remover toothpaste religiously for about 2 months and the results were INSANE. My teeth were so white from just these 2 whitening products. I’d highly recommend trying them together and following the instructions exactly as they say if you really want to see results! They definitely worked for me and I drink a lot of coffee.

Easy to use!
[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.

Decent Whitening Product
[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 Actually See the Change!
[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.

Works fast easy to use
[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.

YES BUY THIS
[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!!

Easy to use and non irritant
[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.

It isn’t good
[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.

So easy to use!
[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.

Great!!
[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.

Works great
[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.

Immediate Visible Improvement
[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.

Works well
[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!

Easy fool proof teeth whitening
[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
