Crest 3DWhite Teeth Whitening Pen – Easy to Use, Erases Surface Stains – Up to 75 Uses per Pen – Convenient, On-The-Go Teeth Whitening Solution

It works! My wife wanted it for some whitening, she can't use straps because of sensitivity. This pen not only works but she can avoid the sensitive teeth.

The Crest 3D whitening pens are convenient for quick touch-ups and overall whitening. I pretty much use only the pen now because my teeth are sensitive, and I don't feel like I'm wasting money on pricey strips when I can use the pen for a shorter period to prevent sensitivity. I like that I can get this between my teeth to remove coffee stains. This is my 2nd pen from Crest. They're easy to use, and brighten my smile fast.

This is easy to use. It works well but I've used other whiteners that have worked better and faster.

Great product that works!!

This product I suspect will work on the right combination to a person’s chemical ability to react to it. Meaning that it depends on how your teeth will react. For me, my teeth were permanently stained from tetracycline poisoning and getting beautiful white teeth is difficult.

Really works to brighten teeth quickly!

I’ve tried a few other pens and whitening strips and I really liked this pen. It’s easy enough to use, is super gentle on my gums, and is very effective at whitening. The strips leave my teeth feeling sensitive, but I’m not experiencing any irritation from the pen. I used it for a week straight and haven’t touched it since and my teeth are still looking naturally white. I’ll probably go back for a touchup in a month or so.

10 out of 10. My go to product for white teeth. Dental professional with over 20 uears experience and won't use anything else.
