As it turns out, observing your tongue doesn’t just apply to your speech. There’s a lot your doctor—and you—can learn about your overall health just by looking at the color, size, and texture of the unsung hero of your mouth. You already know that your tongue is essential for tasting and digesting food, as well as for speaking. But because it’s an integral part of several important bodily functions, paying attention to its shape and changes can give you an early warning of larger health problems. This is one reason your doctor asks you to stick your tongue out during your annual physical exam. And why your dentist might ask about your hydration or hygiene after taking a quick look at your tongue. In general, a healthy tongue is dark pink, moist, firm, and covered with small bumps called papillae. If your tongue doesn’t look like this, get it checked out—it may be trying to tell you something.
