The short answer as to why some people bite their tongue when concentrating is that the tongue requires a surprising amount of brain power to manage- beyond general motor control, it’s covered in various types of sensors constantly providing feedback to your brain about what’s going on in your mouth and making sure your teeth aren’t mashing the tongue.
