EverSmile AlignerWhite – Travel Size Teeth Whitening Pen with Fresh Mint Flavor (2ml Pack) – Gel Whitener Compatible with Invisalign, ClearCorrect, Essix, Hawley, and Other Aligners and Retainers

It works! I put it on my invisalign before bed and my teeth have been progressively lightening. It hasn't caused any sensitivity and is very easy to use.

I liked the idea of using my aligned trays to whiten at the same time. My teeth were a tad bit sensitive at first but I realized I was also using too much when my first pen ran out earlier than I expected.I started being careful about where and how I was applying it, as well as using it every other day and I’ve gotten into a good rhythm with it.

Didn’t really notice improvement.Otherwise easy to apply and I didn’t notice a taste.

You only get like 3 applications and then it just clicks when you turn it and nothing comes out.... and I my teeth didn't whiten... not even slightly... so not enough applications and it doesn't whiten

It’s just basically like any other whitening gel in the market but I don’t imagine you’d want 5% hydrogen peroxide on your teeth the entire night. I’ve developed teeth sensitivity after two uses of this kit and I’ve never had any problems with any whitening products in the past.

The box was intact but the tube was completely empty.
