I do this a couple times a week for like 20 seconds before i brush my teeth at night and it actually made a big difference, so i don't know why everyone is saying it takes years, i noticed within a week. I've been to my dentist twice since i started doing it and they never said anything about my gums or teeth being unhealthy, they actually said my mouth looked very healthy and I have perfect teeth.
