Ah, tooth pulling horror stories. When I was about four I had an abscessed tooth that needed to be pulled. The novacaine or whatever they were using (circa 1953) didn't take. The dentist (now long deceased) wouldn't believe a four year old, so the tooth was yanked without benefit of any nerve deadener.

Fortunately, the body has no memory of pain.

(But 56 years later, I remember...)
