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.
