The Mentos:
It is after the first bite to the chewing gum.
Harder shell, soft core.
The core is largely composed of Xyilit.
And I suppose that's true.
When chewed you could tell how the tooth surfaces are smooth.
The chewing gum holds a sufficient time for me or this is "chewed" feels.
So if you want to do something good for his teeth and also in respect of looking at the price, should be sufficiently happy with the chewing gum.
