As if anyone really needs a reason to eat good cheese. But you might as well have another reason to feel good about it. Aged hard cheeses are actually good for your teeth. They provide a good source of calcium and phosphorus minerals that your teeth need to remain strong, and tend to have lower levels of lactose (the sugar in dairy products) than younger cheeses. In addition, hard cheeses stimulate salivary flow which helps to buffer the acids produced in plaque.

Anybody worth buying from will happily oblige, and even offer suggestions to suit your tastes.
