This may seem like a silly question but is having small cracks in your tongue normal? I don't know how long they've been there, I just noticed them now when i studied my tongue and freaked out. There are a few of them in the middle of my tongue and they're not deep. I already googled it and found out that if you have cracks in your tongue, you might have a fissured tongue. But I looked up images online and it looks far worse than mine does.
