Xylitol is the primary sweetener in our toothpaste (and it’s actually in there mostly to help with remineralization). There’s some data that suggests that stevia also helps to balance the oral microbiome because like xylitol, it’s a low-glycemic sweetener, and suppresses the main thug bug implicated with tooth decay. But really, we included monk fruit, stevia, and several other ingredients to help improve the flavor of the formula. Rest assured, there’s only a very small amount of stevia and monk fruit in the formula, and they simply help to round out the paste flavor profile, helping you have a big Smile after you brush!
