Tooth whitening kit

I can say that this kit comes with a lot of whitening gel.  It has two mouth guards and two lights.  I'm sure you will get the results you desire if you can tolorate using the light for over an hour each time.  I had my own bleaching tray witch was custom made to fit, so it was easy enough to now get the gel on my gums.  I still wiped my gums many time to keep the gel off of them.  Holding the light in my mouth was a chore as well as having the mouthful of drool everytime I took it out to check on my progress.  I give the kit alone a 4 star rateing.  The results are really up to the person using it.
