I bought this product as I’ve been reading of the benefits to dental health with the use of small amounts of xylitol following eating or drinking. I’ve noticed already after just a few weeks of use that I have less tartar build up and my teeth feel smoother when I run my tongue along my teeth and gums. Will continue to use this product as it is very cost effective, you only need 1 or 2 mints following meals and drinks to gain a positive effect so 1 container should last ages.
