They don’t snack between meals.

Saliva is important for cleaning and protecting your teeth, Dr. Quinonez said, but constant snacking and grazing creates an imbalance that prevents it from doing its job, so they try to stick with three meals per day.

They also don’t drink sweet beverages like juices between meals. If they do want them, they enjoy them with food. Even then, Dr. Quinonez said, it’s better to gulp and not sip to minimize the time your teeth are exposed to the liquid.
