Great way to freshen up throughout the day if you’re on the go
Good snack for after meals. I don’t exactly know the chemistry in this but after a long day or drinking sweet coffee, after eating one of these on lunch my teeth actually did feel clean like the little furries on the back teeth went away. I obviously still brush but I like these for after meals or when I have several cups of coffee as I like mine a little sweet. It’s a good way to add to your normal everyday hygiene routine I think. I don’t eat them super often, maybe one every few days if that.
I’m a huge believer in xylitol and helping reduce acidity in your mouth to balance ph. It does so many amazing things like reducing acidity and helping to produce saliva. My fav xylitol products are these, Dr John’s dye free lollipops, and pür gum (aspartame free).
Super important that if you have dogs you keep it away from them as it’s extremely toxic to them. And also everything in moderation bc consuming too many at once can cause diarrhea and bloating, so I’ve read.
