Teeth Whitening Pen with 4x3ml Natural Tooth Whitening Gel Removes Stains Safely,30+ Uses, Painless, No Sensitivity,Travel-Friendly, Easy To Use,Best Effective Tooth Whitener

Love these. Super easy and noticeable change.

I've used these a few times now (not long term, to be fair - just a few days in a row) and don't see any results. But they also don't cause any teeth sensitivity and they are very compact + easy to use, so there is potential for whitening effects to show up after more time. Personally, I see much quicker, more noticeable results with Meijer brand whitening strips for just a few dollars more. However, you get more uses out of this whitening pen pack, so it's a great value if it happens to work for you or if you're a bit more patient.

I have a very sensitive nose and smelled Clorox type smell while applying this to my teeth which scared me but either way, it pretty much whitened my teeth before my eyes! I forgot to take pictures but I had darkness between my teeth and I focused the product there and it worked miracles! Where White strips couldn’t reach this product did! I would recommend to everyone. Only give the product a four-star because I’m not sure if it contains some type of Clorox type ingredient.

I had previously used the 5 - Minute Whitening Gel and it was ok over time, about 8 weeks. But this whitening pen showed results right after the first use. Before I used it, I held a square of white toilet paper to my teeth. After I twisted the bottom to release the gel, I applied a thin layer to each tooth and held my smile for :30 seconds, as instructed. After 30 minutes, I gargled and was amazed at how much whiter my teeth were. What I would like is if the instructions were written on a piece of paper along with the tooth color guide found inside the box. I had to turn the box over and sideways to find the instructions. Also, the Amazon description says more than on the box. It's not clear on or in the box as to how many uses are available for each of the 4 pens. And also, that it's safe for daily use. All in all? Worth the $12.

Terrible taste— and directions say not to get it on your gums. That’s nearly impossible since it needs to stay on your teeth for about a half hour.
