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.

You already know that your tongue is essential for tasting and digesting food and for articulating speech. 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. This is one reason your doctor has you stick out your tongue during annual physical exams. And why your dentist may inquire about your hydration or hygiene after one glance at your tongue.
