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

This works remarkably well. I could see a result immediately after applying it to my teeth. Subsequent applications have not been so dramatic, but my teeth look better everyday. I've only been using for 3 or 4 days so ther should still be lots of improvement. I drink a lot of tea so that is my major source of staining. I would definitely recommend and I will buy again. I have very sensitive gums and I've had no problems so far.

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.

We use the pen to get in between the teeth and along the gum line. It’s a great addition to the Crest white strips.

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!

Works well. Better than strips. Easier

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.
