Teeth Whitening Pen (4 Count), No Sensitivity Teeth Whitening Gel, Effective Teeth Whitener, Travel-Friendly Tooth Whitening Pen, Carbamide Peroxide Tooth Bleaching Gel for Adults

Do these work to whiten your teeth? Yes, noticeable whitening the very first application. They do not cause sensitivity and the application is easy and tidy. No tray mess, just a nice easy paint on brush tip. Very economical and better results than strips. I love them.

So easy to use and effective! Just spin the bottom to get gel on the brush and paint your teeth. I keep one in the bathroom, purse and desk at work. Cost is great and super fast shipping.

I’ve tried a LOT of products to whiten my teeth over the past 20 years. Most caused pain and sensitivity with less than desirable results.Finally, I was pleasantly surprised to find this product. No pain or discomfort and no ongoing sensitivity regardless of how often I use this product. The results are more than I ever dared hope for. I found that using a common dept store brand charcoal toothpaste helped to perfect these positive effects.Great price, very effective, no side effects just white teeth !

These teeth whitening pens definitely get rid of stains, and the results are fast. My teeth were whiter just after a couple of uses, and they do NOT make my teeth sensitive like other whiteners. It's easy to apply and is very affordable compared to other similar products. My 9-year-old daughters even use them. The only reason I give them 4 stars is because they don't make my teeth bright white like professional whitening does, but I'm still very happy with the results.

30+Years of tobacco and coffee. By day 5 my teeth were gleaming white. Easy to use. No mess /aftertaste. No discomfort or "chemical" reaction noted. I only use every couple of days now! Pack of three..well worth the purchase. Highly recommend!

The SmileShark teeth whitening pens are excellent. I just reviewed my past orders and was surprised to find that I have ordered these pens multiple times They work and are reasonably priced! I highly recommended this product!

It does as good as it can.If you have tough enamel (usually yellowish); there’s only so much any of these products can do. With the light, this stuff, and a “3-D” whitener product, with whitening strips- give, “some” results.Use care- they can cause some major sensitivity/pain when used this heavily.

This teeth whitening pen is super convenient and really works. My teeth looked noticeably brighter after just a few uses! I love that it’s gentle with no sensitivity, plus the travel-friendly size makes it easy to use anywhere.
