this is a varnish - it's just a very weak one. you're supposed to leave it on your teeth, after brushing, rather than brush with it. i think i'm ok with everything in it, including the xanthan gum.
if it's not covered, i may need to varnish them myself.
this is 5000 ppm fluoride, in the form of sodium fluoride. i could try a gel at potentially 9000 ppm. the varnish would be 22500 ppm. but, there's an offset - you don't varnish every day. i simply don't know if using the prevident every day for a week is as good as using the varnish once a week.
*shrug*.
let's give it a shot.
and, yes - i'm swallowing. not spitting...
