No cavities a year later.
My son has an aversion to brushing his teeth. While he will only use water, I know a cleaning paste is needed. I can slip this on his toothbrush before he makes it in the bathroom and he doesn't know it. However, it has to be a small amount. It seems to work the same as store brand toothpaste.
Having used only it and water since capping seven teeth with cavities, we visited the dentist a year later. No cavities! We will continue using these in combination with the children's probiotic vitamins found on this site.
