GLO ScienceGLO Classic Brilliant Teeth Whitening Device Kit w/Patented Warming Mouthpiece and Blue LED Light Technology — Designed for Sensitive Teeth, White Device

I’m gonna give it one more night of charging in a different plug. If it doesn’t stay charged and work I’m returning it.Edit: It was the plug that was the problem. Also, you have to be sure you charge for a really long time. It works just fine now.

Works! I've tried whitening strips, gels, take home kits from the dentist, charcoal, peroxide, baking soda, etc, and NOTHING worked for me. I used Glo Brilliant and within 2 uses the difference is evident! I posted some photographs so you can see. My teeth were on the 10 level and now they are about a 3 on the color shade chart! I used the system for 5 consecutive days at 32 minutes each time, I think one day I used the system in the morning and again at night 🌙 🙃. My teeth still have a natural yellow hue to them but they are much lighter. Oh, I have a habit of biting the mouth guard. 😬 Try not to do that, just relax your mouth while you wear it. My teeth had some stubborn plaque looking stains, but Glo removed them! Make sure when you apply the gel you get in between the teeth. I read somewhere that once the gel is opened its only good for 7 days. I used TWO gels in 5 days. The instructions recommended to use a new coating of gel after each 8 minute round but I reapplied the gel after every 16 minutes instead. The gel barely has a taste to me. I feel like I look like I take good care of myself now, which I do! It's a satisfying and elevating feeling. I like my Self better and feel closer to my Self for having used this product.

This system definitely works to whiten teeth. Everyone's teeth are different and I imagine everyone gets very different results but it isn't snake oil - it does do something! I have very sensitive teeth and have steered clear of whitening for years. During the pandemic I've found myself drinking a lot more tea and that has really discolored my teeth and was starting to get embarrassed about them. I bought this device since so many people say it's good for people with sensitivity.I used the device as instructed. It never bothered my teeth at all. It did start to irritate my gums a little, but nothing too bad and only while I was actually doing the whitening. What I did find, is that I was incapable of keeping my tongue completely away from the whitening product (especially because there's a lot of saliva build up and spitting involved). It really hurt the tip and side of my tongue on the days I was using it. I had to stay away from certain foods which was a bummer. After the recommended 5 days of use, my teeth were absolutely whiter. I didn't have Hollywood level whiteness, but they were a lot better than they had been and I was no longer embarrassed. I could have gone on and done more whitening, but my tongue couldn't take it anymore. I will probably go back in a couple of months and do the process again.I feel like I can definitely recommend this to people with sensitive teeth. I think everyone's whitening level will be different (some might be more or less than me) but it does work and depending on your level of tolerance for the whitening product, you can likely get to your desired level.

We had previously tried the GLO Science 10 Day Teeth Whitening Treatment - which is just the vials and the lubricant, but decided to try this higher tech approach and found that it does work quite a bit better than just the vials by themselves.At first we were worried that it might be cumbersome, but the device is small like an mp3 player and hangs around your neck from a lanyard string. The mouthpiece is like having a sports mouthguard in and is barely noticeable after you've had it in for a minute or so.Because you can wear it around your neck, it is therefore hands-free and you can go about other tasks while you're wearing it - which is helpful, because the treatments are four back-to-back 8-minute sessions; so it is 32 minutes altogether, every day for up to 10 days. If you're doing other things, you don't even notice that you have it on; the device glows when it is on and blinks when a session has ended.We found the taste of the whitening gel to be pleasant, kind of sweet, minty. You don't have to try to not swallow while you're wearing this - it's perfectly fine to swallow some of the whitening gel - I did and there was no stomach upset or anything because of it.The blue glow is kind of neat, like something from a sci-fi movie.The whole thing - vials, device and mouthpiece, and instruction book come in a handy travel or storage case.We really liked i! We're gonna order some extra vials so we can keep using the whitening device once the original supply of vials runs out.We think it's worth someone trying out if they want whiter teeth with little or no hassle, because this Glo device is just super easy and really convenient to use. And it will brighten your smile!
