Teeth Whitening Pen (4 Pens) for Teeth Whitening, 40+ Uses, Effective, Painless, No Sensitivity, Travel-Friendly, Beautiful White Smile, Mint Flavor

I like that this whitening product has the carbamide peroxide in it. It is the right amount for in home use. I’d suggest wearing this between 2-4hrs a day & probably takes 7-8wks to whiten. This is how I’m using it. Just a word of precaution, if you feel sensitivity, don’t wear ur tray as often. I haven’t had any sensitivity yet. The price is great & it beats spending hundreds of dollars at the dentist office.

I will admit I have only used the product for two days as I just received it yesterday, but as someone who has VERY sensitive teeth I can speak in the fact that I have not experienced any sensitivity at all and that isn't something I can say for whitening pens I have used in the past. As far are how effectively it whitens, I will have to update in a couple weeks.

I've tried other brands of whiteners, and so far this works the best. I've noticed a difference in just two weeks of daily use. I have sensitive teeth, and this product is very gentle. Easy to use, and leaves no yucky after taste

Works great easy to apply

My husband thinks it works but I see no difference after 3 weeks of use.

This item size is works for me so well when I have tip. The solution is drying out on my tooth quickly that much faster than I thought.

Great

I found this to be an easy and non-expensive as well as non-invasive way of whitening your teeth. It doesn't taste yucky, and it seems to work fine. You have to use it repeatedly to see a difference. I think it works?
