Mom, should I call the doctor?

Mom, should I call the doctor? Yesterday my son fell and bit his lip((( He eats and drinks normally, sometimes he even wants to poke with his finger, he acts as usual, today he wanted to brush his teeth, I gave him a toothbrush, everything is normal, I think he's not worried about this hematoma. But still, should I go see a doctor or will it pass on its own?
