No sensitivity issues and works!
Size: 4 Count (Pack of 2)
I have what I would consider sensitive teeth and this doesn’t bother them one bit. I have used nightly for about 5 nights and can see a difference in color but again, no pain or sensitivity problems! I would recommend to anyone who asks what product to get for whitening teeth.

Impressive work...
I've used those whitening kit and it's my first time with something like this. I've done the charcoal toothpaste and working toothpaste and they made small changes to my teeth over a long period of time, but the whitening kit was a bit different. I applied the gel on my teeth and used the LED mouthpiece. There was a small change and a bit of sensitivity in my teeth so I waited a few days for the pain to reduce. I didn't realize that the sensitivity feel for for that very purpose. After a few days I applied another coating and used the sensitivity gel. The results were significant my teeth were two chart shades different. I was very impressed. I would recommend this for whitening your teeth, but if you feel a bit of sensitivity after use, use the sensitivity gel and red light setting on the mouthpiece. It really does help.

Perfect Match with the WhiteBrite mouth whitener
Size: 4 Count (Pack of 1)
I purchased the White Brite teeth whitener unit & ordered the gel pens to go with it: this review is for the gel - however have to mention the little mouth brighter is AMAZING! Works as well as getting 500$ whitening at dentist! 🦷 … The gel is a perfect match for it…I used continuously for one week - saw a 85/90% Highly recommend the mouth whitener & gel pen!
