On-The-Go Teeth Whitening Pen, Anytime Treatments, Mint Flavor, 0.13 Fl Oz

Works amazing. I don’t use it nearly often as packaging suggests but results are still noticeable after one application. I continue to buy this over and over again with great results each time. I occasionally put it on before bed and wake up with whiter teeth. Just put on some chapstick or something because it can dry out your lips a little if your prone to dry lips

Life changing. I've never had teeth this white since I was a kid, using it once a week at night really makes a difference!

Works well! Teeth whitening in days.

For $10 or whatever, I used religiously and maybe, not sure they got a tiny bit whiter. I smiled for 15 minutes so my lips wouldn’t move the serum, too. Maybe worth a try. Looks like Crest white strips may work better though their reviews aren’t great and they are $50 and up. Do NOT get the $300 Zoom treatment in the office. No one tells you you have to eat only white foods for 4 days and hrs later you get what they call @zingets” that feels like being zapped down into the nerves under ur teeth. The pain is so intense. And mine teeth got extremely white, but a week later darkened. Waste of money and pain is awful, not yo mention I had overlay on my 2 front teeth, and it doesn’t work on anything but 109% natural teeth so they wanted to charge me to change my overlay ($600) to match. So anyway, this product is kind of a waste of time. Painting it on moves it around and removes it.

It is truly a great product if you do not drink coffee or tea. I use it religiously. I keep ordering it

Works great especially for coffee and tea stains. I get compliments all the time!

I bought this based on other reviews I saw from people who'd bought it and swore by it. The package was really cool. It arrived quickly. It's just like the pictures suggested as far as what the actual pen looks like. But you click it or whatever until some finally decides to squirt out around the brush and use the brush to brush it on to ur teeth. It's thick and then because your mouth and teeth are wet, it gets all messy and it's a gel like substance. By the time you get enough on there and try to apply it correctly It's all about washed away by your saliva. If you do manage to get it to dry it looks caked on your teeth. I have had to brush mine every time I've tried to apply this stuff and as for whitening, it hasn't for ME. But that being said. My stains are pretty bad. My teeth in their entirety are terrible. So it may just be me. If you have some bad stains going on, I suggest a dentist. Bc by the time you buy up all this stuff you may as well have just saved up and gone and had it done professionally.

Love this stuff wish they still made it

This product made my teeth sensitive and did not do any whitenenint, in fact it made them yellower, it is a really bad product and you should not waste your money like I did.
