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

Works great with no sensitivity

Purchased for my husband, definitely can tell the difference

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 got this on sale and I have only used this twice. I could already see the result so I am very impressed.

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.
