I’ve had two wisdom teeth removed as a teenager since they were growing horizontally. The two others were left there because they were pretty far in, removing them was riskier and they weren’t causing any trouble. Gum was tender lately and this morning I realized this is because a wisdom tooth just erupted.
Moral of the story: there’s no age for coming out.
Weird. Did your dentist say it rotted because you didn’t use it?
I think so, it was a long time ago but that’s what I remember the reason was, like chewing stuff cleans off plaque and when it’s not being used to chew it just builds up.
Probably I’m just misremembering though ¯\_(ツ)_/¯
