Chewing his tongue?

My 5 months old is still teethless and there is no sign of a tooth 🦷 yet. But yesterday night, when I was putting him to sleep, I noticed that he was chewing his tongue and it was making a kinda painful noise. But he was doing that for like 20/30 minutes until he fell asleep. My son doesn’t like pacifiers, we tried different brands and shapes. He hates them 😔

Any mamas experiencing the same? Is that normal? Can that hurt him?

Thanks a lot 😘
