Teeth Whitening Pen 4+1(5 Pack), 70+ Treatments, Use Twice a Day Up to 1-6 Shade Whiter in 1-2 Weeks, 4 Whitening Pens plus 1 Desensitizing Pen, Effective, Painless and Enamel Safe Teeth Whitening Gel

I purchased this awhile back and then again recently. For years I got my teeth whitening gel through my dentist but it got to expensive. The pens work very well and it is very easy to use with no messy trays. I always felt like whitening my teeth with the trays was a chore. These pens are easy and really whiten your teeth. I never haveany sensitivity from these pens.

These are so portable and very easy to use. Saw results and they are so reasonably priced. I will purchase again.

Just what I needed. Well-packaged and nicely priced. I'll order again and again! The included desensitizing pen was a nice touch!

I bought this product because I could not stand strips anymore and the pens were cheaper and seemed easier to apply. The product worked well and I did notice a whiter difference!!! Will buy again!

These teeth whitening pens are great to throw in your purse or bag to have one with you wherever you go. It’s a thicker gel that stays in your teeth and just just come right off and I started to see results after the second use! You get 5 pens so, they last for a good while making them a great deal for the price!

Very good results. I use it once a day, keeps my teeth quite white. If I don’t use it for a few days, I can really see the difference.

Easier than white strips and it works well.

I used these last night and this morning and my teeth look two shades whiter! So much more convenient and less expensive than white strips. These were easy to use and clearly work.I have two problems - 1. Instructions are not included in the package and 2. The desensitization gel is not sold separately.I applied the desensitization gel first and my teeth immediately looked whiter, though I think that's the blue counteracting some of the yellow (though purple would be better! blue seemed to have some impact). I then applied the whitening gel. I have a mouth opener (tool that keeps your mouth open) from a set of white strips that insisted on dry teeth and I use that to apply and then count 30 seconds. After that, just remember to wait 30 minutes before eating/drinking. This makes it perfect before bed.Having not tried the pens without the desensitization gel, I'm not sure if my teeth are going to be sensitive to the gel without it, but presumably I'm using a similar amount of each, so I will run out 4 times faster. There doesn't appear to be a way to purchase the desensitization gel directly from this seller, so I will likely look into something else once I run out.My teeth are usually whitish - I try to take time to follow a 7 step dental hygiene routine at night, and my teeth usually look whiter. But, who has time every night for that kind of routine? To supplement, I use white strips from time to time, but they have their own issues and can be pretty expensive. This product is much less expensive. I also like that I can target individual teeth. I have a molar that looks darker and I can never tell if it's just shadows or what, but, I can now try whitening just that tooth.Overall, I'd recommend, just note the instructions from the Amazon page and if you have sensitive teeth, you may need to buy another product to use all the whitening pens included.
