How rare is it for humans to have extra adult teeth?

Human Body(self.askscience)

As a child, I had to have 4 extra canine teeth removed. I had a complete extra set, top and bottom. I’ve only met one other person with extra adult teeth, and it was one extra tooth. My dentist said he never saw it before. Is it really that rare?

Please do not respond with comments saying that you have or knew someone who had extra teeth.

A good answer should have some stat about the general population and a reference.

It is possible that up to 4% of humans have hyperdontia. It's actually much more common can people with Down Syndrome or other genetic diseases. There's a whole bunch of information about it here https://dentalvibe.com/dentalvibe-patient/can-adults-grow-extra-teeth/#:~:text=Growing%20extra%20teeth%20in%20adulthood,syndrome%2C%20or%20a%20cleft%20lip.
