Review (5/5): Best whitener for the money
I had professional custom-fitted teeth-whitening trays created for me by my dentist. He sold me the teeth whitening gel. But then I figured out that I could get the exact same teeth whitening gel from Amazon for a fraction of the price charged by my dentist. This teeth-whitening gel is identical to what my dentist sold me, but for a third of the price. I highly recommend for someone who has custom-fitted whitening trays. Don't leave gel/trays in mouth for too long, since it will eventually irritate your gums, as all these Professional-grade Hydrogen Peroxide-based gels will do. I can't tolerate more than 50 minutes; then I must remove from mouth, and immediate rinse mouth of all gel residue. I'm Robert, and this is an authentic review by a real user. Cheers to your new, whiter smile. :-)
