[This review was collected as part of a promotion.] It seemed to work well although i have only used it once so far. i love the idea of it it seems very covenient vs the strips but idk. I like it we will see how much it does!

[This review was collected as part of a promotion.] I received this complimentary from Influenster and Crest in exchange for my honest review. This system really whitens! Definitely would recommend!!

[This review was collected as part of a promotion.] We go for teeth whiteners and I really liked this one since I don't feel any sensitivity in my teeth after using it, and with its LED light it gives greater effectiveness.

[This review was collected as part of a promotion.] The pen works, but not comfortable on sensitive teeth. Easy to apply. The whitening part works, but for people with sensitive teeth , it feels bad

[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.] COMPLIMENTS OF INFLUENSTER: I am sampling Crest 3DW pen. I’ve only been able to use it twice so I’m not sure how accurate my review can be, but I do feel like my teeth turned a little whiter in my problem areas. I like using the pen to apply the whitener because it’s more precise. The light helps see the problem areas better. I felt like a professional using this pen. I didn’t care for the flavoring. It tastes like medicine. But for the results you get this is a great inexpensive product for your teeth.

[This review was collected as part of a promotion.] Every time I try to use whitening product I stoped at the 3rd day because of sensitivity, well let me tell you, not this time!!! I am very excited and didn’t write this review until day 5 of treatment. I can see a little difference but hey I’m in day 5. The favor is not the best but is not horrible. The packaging was perfect.

I didn’t get the results I expected but still using.

I have seen zero change
