Teeth Whitening Pen – Extra Strength 9% Hydrogen Peroxide, 40+ Treatments, No Sensitivity, Removes Coffee Wine Tea Stains, Whiten Teeth Fast, Enamel Safe, Made in USA, 4mL

I waited to review this product until I'd seen my dentist, who gave me the thumbs up and assured me that I hadn't harmed my enamel or anything else by using this pen. :) I purchased the pen about 2 weeks before my regular 6-month cleaning appointment and used it as directed...well, less than directed. I'm in my mid-fifties, and my teeth were stained from a LOT of coffee through the decades. They had a yellowish cast to them and were darker towards my gums. I wasn't after paper-white teeth or that weird bluish-white color; I just wanted them to be their natural ivory again, without the discoloration towards the base. This product really delivered. I saw a noticeable lessening of the yellowy tinge and the stains after the first use. By the third use, all stains (ALL) were just gone. My teeth were a healthy ivory again and the color was consistent all the way to the gum line. I didn't experience any burning or irritation at all on my gums, but I can't speak for someone else's sensitivity. The pen is crazy simple to use: A couple of turns of the clicky base, paint your tooth/teeth, and done. No trays. No light. No strips. I especially liked the precise nature of the little brush: Once I was happy with my teeth overall, I concentrated on just painting my canines (which were a little darker than the rest of my teeth). It evened them out beautifully. Note(s): This gel is clear and so is the brush, so don't make the mistake of thinking that there's no gel on your brush and get all click-happy. Give it a second to coat the brush before you rotate the base too many times and end up with a big old glob on the brush. Also, as my dentist pointed out to me, my happiness with the pen was because I wasn't expecting blinding white teeth. I just wanted the stains gone, which it did thoroughly and easily. I didn't even use the pen twice daily for 2 weeks: I felt like great results were achieved after just a few days. If my teeth start to get discolored again, I'll use the brush again for touch-ups. I don't expect that as I'm using a whitening OTC rinse now which seems to work just fine for "maintenance." Excellent product at an affordable price!

Ordered 2 of these a while ago and they worked as expected. Ordered 2 more and one of them wouldn't push the gel to the tip no matter how many times I turned the bottom. Contacted customer support and after a few emails they wanted to make it right. Promptly sent me a replacement and got it by USPS in less than a week, even with the snow storm we had. Customer Support is top notch, and works with the customer!!! As far as the whitening gel, my wife an I did notice diminishing yellowing and shades of white coming back. The taste isn't terrible and not real noticeable (at least to me). The gel did seem to foam slightly in the gum area. Perhaps I put too much on. I do tend to overdo things! At any rate the pens to work and do remove stains and such. I will buy this brand again.

pretty good. Of course, I would like my teeth to sparkle but it will do. Very easy to apply and that was my main focus.

I found that the product did not hurt things and that it helped very slightly. The claims on the packaging are reasonable and not too ambitious - they are not telling you that you'll get dental office results or anything - but my results were less than what the package said. NOTE: I may not have used the product as well as or to the extent that I could have. The product requires no eating or drinking for one hour after application, therefore it was pretty difficult to find that time in the mornings, therefore I made the decision to only use it once per day at night. I felt like I might have been making some tiny progress, but the product also states that you should stop using it after 14 days, so I did and the results were minimal. It also takes a little bit to get the technique right - the gel comes up through tiny bristles and it's hard to make out when its flowing out and therefore to get the right amount on the bristles - I felt like maybe I did not use enough of the product at the beginning of my treatment to get a good result. It's a nice minty flavor, but you're not really supposed to ingest it! For the price, I'd be willing to try it again in a couple of weeks from now - this time, I will try to carve out some time in the morning to do it twice per day and would feel like I'd be better at applying it.

I love this product. Its my second one it's convenient size makes it very handy and it works.

I used this product twice and have clear, deep scratches in my teeth where it dissolved my enamel. My teeth are also sensitive to the touch where those scratches are, and they are overall sensitive to cold and heat. My teeth also don't look any brighter or whiter, but they did inexplicably turn brownish yellow between my bottom front teeth and I have a few patches where they turned translucent grey. Additionally it kind of looks like I have raised squares in the center of my teeth because I first outlined where the gums were to avoid contact with my gums and then did a downward brush stroke to cover the center of the teeth. It seems to have dissolved even more of the enamel around the margins or my teeth, leaving that raised square shape in the center... I brushed my teeth prior to use and rinsed my mouth extremely well to be sure there was no residual toothpaste. I then very quickly brushed this product on according to the directions with a small amount of gel on the brush and left on for just one minute as instructed. I did not eat or drink for over 8 hours after applying as I applied about an hour before going to bed. I repeated this process the next night and noticed the damage to my teeth immediately after, then threw the rest of the gel away. I'll be going to the dentist to see if they can do anything to help with the sensitivity or the visible scratches, but from what I've read it seems like enamel damage is irreversible and my best bet for the sensitivity would be a fluoride treatment, which won't help with the appearance, or I can spend thousands of dollars on veneers or tooth bonding which will require upkeep and maintenance for the rest of my life. Overall, I absolutely do not recommend this product.

I wish I’d tried this format sooner. I’ve tried the strips a number of times, but not only did they make my teeth hurt, they were so messy and uncomfortable. This pen is so much easier, cleaner, and comfortable. You just put it on and forget about it. No returning after a set amount of time to remove anything. Also, no weird taste!I’ll definitely have to update my review after a few weeks because I’m only a few days in, so it’s possible that sensitivity comes later or that it doesn’t whiten enough. But I’m not looking for paper white teeth. I’m looking for a natural clean color. The instructions say something about smiling for 60 seconds before use. I’m sure that’s just to make sure they’re dry, so I just dab them with a tissue instead.

Does not work
