The Cinnamon flavor has some heat, but it doesn't hurt my sensitive teeth. My only complaint is that it sells out so quickly.
I purchased the orange toothpaste for my kids and they love it! It has been difficult finds a flavor they enjoy. Will be purchasing more bottles. I purchased cinnamon for myself. Beware it is spicy! I love spicy food but it is too much for toothpaste. I will purchase spearmint on my next order
It's really difficult to find toothpastes that aren't mint-flavored or completely plain, so I was really pleasantly surprised by the orange toothpaste which smells and tastes incredible and actually makes my mouth feel clean. Best of all: it's vegan and plastic-free...the future is now.
