You already know that slurping soda will rot your pearly whites, but now a new study shows that drinking milk may actually help prevent tooth decay. Professional researchers soaked teeth in orange juice or diet Sprite, and then doused them in milk, artificial saliva, or water. Turns out, the teeth exposed to milk had less enamel erosion than the ones immersed in the other two liquids.

The calcium in milk may bind to the acid from the juice and soda, decreasing its effect on enamel erosion. Who’s going to chase pop with milk? No one. So just skip to the last step: Option for dairy, not soda.
