Any idea if these are something to worry about?

The little yellow bits on his tongue! Any ideas?

I can’t see to clearly from that picture but my old boy doesn’t have many teeth at the front now and has some bumps and almost callouses on his tongue where he’s having to use that more to eat the grass
So I probably get the vet or dentist to check if it’s a new thing

He’s had it ever since I got him in October, he had a dental in December but the vet didn’t say anything about them.
