What about one from your health food store? I have been thinking about flouride a lot lately after the dentist encouraged me to have sealants put on my daughter's back teeth. I had them put on some of my boy's teeth when they were small ( they're grown- or nearly grown now ) but knowing all I do now, thought I'd forgo the unecessary chemicals.
Anyway it got me to thinking abbout all the floride I am ingesting throughout the day...I brsuh my teeth three times a day usually. I got a brand called "Jason" but I have not tried it yet. It says the sweetner is stevia. Knowing my luck, I'll have a bad reaction or something to it. lol.
