Turns out watching your tongue should apply to more than just your words. There’s a lot that doctors—and you—can tell about your overall health just by looking at the color, size, and texture of your mouth’s unsung hero.

But because your tongue is such an integral part of several important bodily functions, paying attention to its appearance and changes can help alert you to larger health issues early.
