i don't know about toothpaste....but spry raspberry mints have xylitol and calcium lactate for sure. that's what we buy. they are REALLY delicious too! i purchase from amazon, but lots of websites sell um here's a link to amazon though if interested:
I have SPRY stuff right here in front on me. Berryblast Mints do NOT have any soy in it [it does have beeswax if you are vegan]; Fresh Fruit Gum has soy lecithin and vegetable glycerin in it and probaby the mint gums do as well. The mints and toothpaste have calcium lactate, the gum doesn't.
SPRY toothpaste has silica and vegetable glycerin, among other things.
My mom bought them for me, actually for my ds. But he wasn't too enthusiastic about them.
Zellies uses rapeseed lecithin and Calcium carbonate.
Anyway, my ds's cavities [according to the pediatric dentist we first took him to, $3400 worth] have all remineralized; and we've used just about every thing Xylitol on the market. Right now, he really likes Zellies fresh fruit candies and Emerald Forest sour candies - Grape and Licorice. He'll take Cherry if there is nothing else available.
