ELi5 Why are dental X-rays dangerous enough that you have to wear a lead apron for protection, but ok to blast them into your face?

It's often the case that you take a necessary risk but avoid taking an unnecessary one. There is every reason to x- ray your jaw if you have a problem but there is no reason to let even a small amount of stray radiation irradiate other parts of you while doing so. In particular the parts involved in reproduction, the testes and ovaries due to the remote posdibility of genetic damage.
