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

Best whitener I’ve used. I’ve used trays and light whiteners, and strips. This whitening pen is the most comfortable and has best results.

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.

This worked pretty well, especially if you used it consistently. Super easy application, slight taste immediately after but nothing you would not expect.

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.

I've use several whitening products and I love this one!! I love how you just paint it on. Yes, you do have to keep your mouth open for 60 seconds for it to dry. So much better than strips and comfortable. Also it doesn't taste bad. Quick easy routine to use after brushing teeth. My teeth are looking whiter in just a few days!

This product does keep my teeth whiter.

Works well. Better than strips. Easier

Teens love to use this Pen. Just be careful if you tend to get sensitive teeth.
