[This review was collected as part of a promotion.] Love how easy it is to whiten on the go, no rinsing, just brush on teeth and wait 60 seconds before going about your life. Only catch is that you can’t have food or beverage for 60 minutes but that’s easy if you do it before bed or early morning.

[This review was collected as part of a promotion.] The product seemed great in theory however the whitening pen didn't really do anything. I did not notice any difference before and after while using this product. I would stick to traditional whitening strips

[This review was collected as part of a promotion.] So the packaging was nice, the effectiveness is doable. I would say if you don’t eat or drink constantly, then you would like this particular product. I like it but waiting an hour for the results are a little long, but I’m slightly inpatient.

[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 think this is a great product, the moment you apply the gel you feel it and see it turn white, the only problem is that I drink a lot of coffee but I think if you follow the instructions and don’t drink coffee your will see better results than me

[This review was collected as part of a promotion.] I have been using the product nightly for a week. I like that it’s easy to put on, doesn’t taste weird, and so far hasn’t increased my tooth sensitivity. I wish the whitening was more drastic, but I definitely can see slight improvement with the one week of use.

[This review was collected as part of a promotion.] I have very sensitive gums and I was very excited to try this product since I had control of where to put the whitener. Just within the few days I’ve used it I’ve seen big changes in the color of my teeth. My gums didn’t hurt as well.

[This review was collected as part of a promotion.] This is a great product to use for touch ups or to take on the go. I do find it hard to time consumption with this since you have to wait 60mins for full effects but its still a great alternative if whitening strips hurt too much.

[This review was collected as part of a promotion.] I’ve used this 3 times now and haven’t had any sensitivity from it! I like that it’s a pen, making it easier to use. Sometimes too much product comes out and gets everywhere (I clean it up with a q-tip) I didn’t really notice a difference til after the 2nd to 3rd time. Even then, it’s not a crazy difference, but I think after 1-2 more uses it will really show. :)

[This review was collected as part of a promotion.] I’ve been using the Crest 3D White Teeth Whitening Pen for four days and I’m pleasantly surprised. I’m a daily coffee drinker, so I feel that coffee has stained my teeth somewhat over time. I feel like this whitener has started to remove some of this staining. It says to use twice a day for at least 14 days to see best results, so excited to see what my teeth will look like in 14 days. It’s quite simple to put on, taste isn’t great but not awful.
