Zero White Sensitive Teeth Whitening Pen | Pain Free with No Harsh Ingredients | Enamel Safe | All Natural Teeth Whitening & Stain Removal | Mint Flavor (Pack of 1)

I have been trying this product for a week now. It seems that my teeth is getting whiter, but it only appears after I apply the pen to my teeth (which is every night). When I wake up, my teeth seems to go back to what it was before. I'm a little confuse. I might not be doing it correctly, but I am following the instructions. My teeth is also sensitive. This product at times makes my teeth tinkle, but it doesn't hurt. I just feel a little sensitivity but then it goes away. I will update maybe after another week or when I finish this product. And also the twisty part on the bottom of the pen doesn't twist, so I had to remove the plastic "metal" part in order to twist the pen to get the product out.So far after 1 week, I am just confuse about this productUPDATEI have finished this product, which was about 14-16 uses (which is rather sad considering that it's about $27)...and I did not see much of a change of whitening to my teeth. This item is not worth the hype and the money. I say look for another alternative for whitening.

I bought this cause I see ppl talking about it on youtube a lot lol and I like that it whitens your teeth and it also is safe for your teeth I do think it takes time but it does work I bought this for my dad so I myself haven't been using it but I have tried it like 4 times I sneak it, cause one pen is meant for one person at a time so that's why we didn't share Im going to buy me another one soon everyone should try it it's a lot more safer for your teeth than the other whitening products .

Saw immediate results. Didn't hurt my teeth or make them feel weird. I really enjoyed and will be buying another one in the future.

There are other products that provide better results that I prefer - crest whitening strips and 5 minute whitening gel.

this pen does not work at all. do not believe all of the good reviews online, they are scams. i thought the whole concept was iffy in the first place.

I received the item today and very disappointed with the product. I opened it and turn out to be used, very disappointed. Will not purchase from this buyer again.

I saw results in the same day. Really. I bought this off of hautelook because stuff is always cheaper there. I knew a girl who used these during her chemo and said it didn't bother her teeth so I tried them hoping it wouldn't bother mine either. My teeth already look whiter. My only complaint is that sometimes I don't know if the gel is on the brush or not and it's really weird to wipe the saliva off your teeth before you use the product. And to hold your mouth open not having your lips touch your teeth. But you know I guess it's worth it they are looking good. And I drink LOTS of tea so you know I have some stains

I didn't see a clear difference, and it broke after ten uses. not cool
