Review (5/5): Messy, but miraculous
This stuff is really messy, but so effective. After only a few uses I saw a major difference in my teeth. I've had problems with the chemicals in whitening toothpastes and my dentist advised me to not use them as they were damaging my enamel. But I've had no problem with this stuff. My teeth are whiter and feel so clean. This product is worth every penny.
