GLO Science Teeth Whitening Pen 35 Aplications, Safe and Efective, No Sensitivity, Easy to Use Dentist Invented Whitening Treatment, Travel-FriendlyAre my teeth whiter? Yes. It's not so white that anyone will see me and be like 'wow your teeth are so white!' but it is whiter and I notice it, which I prefer. I have very sensitive teeth and almost no enamel. The pen is a click pen, and you have click quite a lot to get it started. I thought mine was faulty at first, and the clicker even got stuck half way down but I smacked it and it popped back and I kept clicking. The silicone tip has little bristles and it does a good job of coming off on your teeth - I was worried the gel wouldn't grip onto my teeth and would slide, but it didn't. It does have a cinnamon taste, and it does dry in 30 seconds, it was easy enough to smile for 30 seconds and it was on there. Truly I forgot about it after that (don't eat or drink for 30 min if you can). Are my teeth whiter? I couldn't tell after 1 use, but after two, I also couldn't tell... BUT I took a before and after photo (which I'll save you from because my lips look awful right now) and my teeth are definitely visibly whiter! I'm happy with this, it's easy to put on, doesn't make my teeth sensitive, works for whitening, dries quickly, and you don't even have to spit it out.

I used the GLO Science Teeth Whitening Pen a few times and have yet to really notice a difference. Whitening strips work so much better for me.

I love whitening pens normally. They’re usually easy to use and quick. I did Invisalign so I use the pens at night and then pop on my retainer trays. I was running out of my normal whitening pen so I grabbed these. Out of the box it took forever of clicking to get any product to even come out. Then way to much came out. Once I cleaned the pen up I finally got the right amount of product out. My other pens are a brush applicator. This one was is like a little scrubby tip. I want to brush product on not scrub it on. So again another negative for me. The smell and taste were pretty awful to me but luckily once I popped my trays on it was ok. I’ve been using this for about a month and I really don’t see much of a change. Maybe a tad, but my old pens if I used them too much my teeth got almost too white! I’m going back to my old product.

Love the convenience of this pen, just wish the gel would come out a better way. First off, it took FIVEver to expression the gel out. I think I clicked the bottom 50 times before a tiny bead of gel started to appear, I had to aggressively click and slam the pen onto the counter to get more product out. Once I was finally able to get enough product out, I dried my teeth (after flossing and brushing first) and wiped the silicone bristles onto my teeth from premolar to premolar on my upper and lower teeth, I used the box it came in to fan and dry off my teeth. I did this before bed time so I wouldn’t have the urge to eat or drink after. The gel will become stringy once your inner lips and cheek touch the gel and there’s a mild taste to it. So far I’ve used this pen nightly for 4 days and I’ve seen a tiny bit of results. You’re supposed to use it twice a day for 2 weeks. I haven’t experienced any sensitivity from the gel, partly because I’ll use sensodyne toothpaste to brush and the gel is formulated with potassium nitrate that helps prevent sensitivity. Other good ingredients include xylitol and natural antioxidants. Overall good product, just need a better way to get the product out without having to click it. Twisting would be a better option and maybe transparent packaging so you know how much product is left.

This whitening pen is different from others in that it is a silicone scrubby brush rather than a nail polish-like brush. It took me many, many clicks of the button at the bottom to get the gel up the first time I used it. I thought it would never come up the first time. Once it did, it came up in a big glob of clear gel. I had brushed my teeth and dried them then I brushed the gel on. I have sensitive teeth so I was nervous but it didn't hurt at first. The brush is a little hard and I actually could scrub my teeth with it. After a few seconds, the gel started foaming and I started to feel a little sting. I kept my mouth in a smile for a minute or so then let the stuff do its job. I could taste the gel. It wasn't awful but certainly not tasty. I was frothing a bit the first five minutes or so and then the foaming settled down..The label says there is no need to brush your teeth after using this pen but I had slimy gel on my teeth and just had to get it off so I brushed my teeth and they did look brighter and cleaner. I am a heavy tea drinker and that really stains teeth badly so anything that helps me to get the brownish cast off is welcome. This pen does help to remove surface stains but it is a pain to get the gel up and onto the brush and my teeth and gums feel sore after I use it. That is from the peroxide. If you don't have sensitive teeth or gums, you probably won't get any stinging. I like the results but not really the brush and delivery of the gel itself.

The pen is super convenient, easy to carry and conceal. You push the base to get the gel started, once you start to feel resistance, you know it's at the top. When using it, ensure your teeth are dry enough to hold the gel. I like that it is no rinse needed, just wait 20-30 minutes after applying to eat or drink. While the idea is great, the results were minimal. To see max results, the gel needs to be applied twice a day for two weeks. At that rate you would be better going a different route.
