Colgate Optic White Pro Series Whitening Kit, Teeth Whitening Pen and LED Tray, Professional-Level Whitening Set, Rechargeable

Very easy to use. Cleaning the brush of unused fluid was sometimes difficult and obviously the device that whitens my teeth didn’t fit well, but I knew that was going to be the case. I can tell that my teeth are whiter, but my family doesn’t seem to notice a difference. 🥺The unit didn’t always charge correctly but I believe that was sometimes my fault for not getting everything lined up correctly. Overall I believe my teeth are whiter or at least getting there, but I’ve already bought another pen of whitening fluid to keep going till I get the results I want.

I have been using the Colgate pen for over a year, and while it has issues, it *does* work, so I decided to try this kit, which adds the LED light to the process, making it even more effective. The light was easy to charge, and gives you an audible beep at five minutes and again at 10 minutes at which point it shuts off automatically. There are some clear pros and cons to this kit:Pros:- The gel really does whiten your teeth, and it’s fairly easy to apply to the surface of your teeth with the pen, but you need to make sure your teeth are dry before applying. Also, wait a second or so between clicks to give the gel time to emerge. If you rapid click, you will see nothing, nothing, nothing, and then all the sudden a whole bunch of gel comes out.- The 10 minute light session after applying has two benefits: first, it really does enhance the whitening experience and you’ll see results quicker. Second, it dries the gel onto your teeth so it stays on overnight better.Cons:- if you leave residual gel on the fresh tip of the pan after applying, The bristles get sticky and clumpy, making subsequent applications difficult. However, if you are not careful when wiping off the bristles, they will pull out very easily and you will be left with a pen full of gel and no way to apply it to your teeth.- you must act very quickly when applying the gel, as it tends to start to dry and get sticky very quickly, gumming up the brush tip- The LED light tray is made of hard plastic with a silicone bite strip and very thin silicone edges. The hard plastic makes it non adjustable, so it can be very uncomfortable if it doesn’t fit your mouth. In my case it is a tad too narrow and it cuts into my gums, making the 10 minute session feel agonizingly longer than it really is. It’s more comfortable if you just bite the edge of the strip and not try to push it into your mouth, but in my case I can barely catch the edge before this squeezes my teeth and cuts into my gums. It’s doable, but not comfortable at all. It’s only 10minutes though.

This product was a major win for me. I’ve used crest white strips in the past and for some reason they made my teeth hurt, it was excruciating really. I hesitantly gave this a try when it was on sale and I’m pleased to report for that, for someone with sensitive teeth, I’ve been pain free! While the results are not as quick and dramatic as the crest white strips, you absolutely can tell a difference by day 5-7ish. I’m willing to be patient without the agony!

I wasn't expecting professional level whitening, and this at least delivered what i felt was a few levels whiter than what i had prior, but it's so difficult to know if you're using it correctly. The guide says in order to work properly you need to make sure your teeth are completely dry before applying the cleaning solution. Though I have no idea how long after that you can drop your lips. Does it dry immediately? or if you apply it and you drop your lips does it just wash it off and effectively make it worthless before you use the UV mouthguard?But since your teeth need to be completely dry and the applicator can't get wet or else you'll ruin it, this means you can't realistically whiten your side teeth. So if you have a wide smile you might end up having nice white front teeth with darker teeth on the side, lol.All in all, i think it's probably more worth it to just get a professional to do it that can guarantee results.

As a former dental hygienist I was very impressed with The Optic White Pro Series. I felt there could be more instruction on how much follow up should be done after the 10 day treatment. I also could not find out if the Optic White Pen that is sold on Amazon is an equal replacement for the whitening pen in the kit. Info on how often and how long you should do follow up treatments would be a good idea.

Works great with no sensitivity

In my opinion this is just a gimmick. Using whitening strips yielded much better results.

The whitening gel works differently than most others because it hardens into a crispy layer that can stay on your teeth for hours. Does the whitening effect work better than other gels that you wipe away in 15 minutes? That's really hard to say for a home user.It's slightly more inconvenient to use than a standard gel kit because you need to use it right before bed. You can't just use it anytime during the day if you want it to stay on your teeth for hours.You don't get much gel in this kit as you only get a single pen. For people who are hoping for a better effect because it stays on your teeth overnight, it's worth a try. I think I might be more inclined to get a standard set that includes more gel.
