Citrus fruit

Citrus fruits and juices—a rich source of vitamin C and other nutrients—are good for you in many ways, but not when it comes to your teeth. Grapefruit and lemon juice, in particular, are highly acidic and can erode tooth enamel over time. In a 2008 study that involved soaking pulled teeth in various citrus juices, those two caused the most damage. Orange juice caused the least.

OJ is less acidic, Messina points out, and many store-bought varieties are also fortified with teeth-friendly calcium and vitamin D. "Fortified OJ is good for you on many levels," he says. "Drink it, but brush and floss as recommended."
