I was skeptical about a fluoride-free paste, but the Calprox formula really does lift stains without that awful zing in my teeth. My dentist even commented on the brightness at my last checkup, and this little tube has lasted me over a month.

The 72-hour production process is what sold me, and honestly the paste feels finer than anything I've used before. My teeth look brighter after a week and there's zero of that harsh sting I usually get with whitening pastes.

My teeth have been sensitive for years, so I was nervous trying a whitening toothpaste—but the Calprox formula hasn't caused a single twinge, and after two weeks they look noticeably brighter. The tube is small at 1.4 oz, which is my only tiny gripe, but a little goes a long way.
