You probably dont spend much, if any, time looking at your tongue but this body part can actually reveal a lot about your health.

Take its shape, for example. A scalloped tongue is when, as the name suggests, there is scalloping or indentation of the sides of the tongue, Dr. Neeraj Panchal , chief of oral and maxillofacial surgery at Penn Presbyterian Medical Center, told HuffPost. It typically arises from the tongue persistently pressing against the teeth.

This condition, also known as a crenated tongue or pie crust tongue, can be seen when you stick your tongue out. Look for the presence of irregular ridges or waves along the lateral borders that seem to imprint the shape of your teeth, Dr. Soroush Zaghi , a Los Angeles ear, nose and throat doctor and sleep surgeon, told HuffPost.
