ELI5: When a baby is getting its first teeth, you're supposed to give them something to chew on to dull down the pain. How come when a teenager is growing in their wisdom teeth, they don't feel it until they start to disrupt the other teeth?

Source, 16 year old who was a "pain in the ass" according to my parents when I was getting my first teeth. But with my wisdom teeth starting to appear, I don't even notice them growing in. Why does it hurt so much for a baby to get their first teeth?

Don’t quote me on this, but you could flick a baby’s wrist and it would most likely hurt. A lot of stuff with them is due to their lack of pain tolerance. They simply can’t handle being uncomfortable. But that may not be completely right.
