I have always had little rips all across the sides of my tongue. Its kind of like the ones you get when you eat a lot of sour candy. It doesn't hurt or bother me but it is strange and I'm wondering if it is something serious. Again on the sides of my tongue there are a bunch of rips, I've had it for as long as I can remember, it doesn't hurt at all, and I just want to know what it is. Thanks in advance for your help!
