Cheese and Dental Cavities

Ever since lab studies more than 30 years ago found that rats fed cheese didn’t develop cavities, this dairy food has been touted as being good for teeth. Some human research also supports the idea that cheese does not promote cavities and may help prevent them. Cheese boosts the flow of saliva (which washes away debris and neutralizes acids, thereby decreasing tooth erosion) and increases mineralization of enamel (thanks to its calcium, phosphorus, and protein), among other proposed mechanisms. But it’s not known how much cheese you have to eat or how often to get a benefit.
