- Hermione Granger: "My parents are dentists. They tend to people's teeth."
- Horace Slughorn: "Fascinating. And is that considered a dangerous profession?"
- Hermione Granger: "No. Although, one boy, Robbie Fenwick, did bite my father once. He needed ten stitches."
- — Hermione Granger and Horace Slughorn talk about an incident with Robbie Fenwick.[src]
Robbie Fenwick was a Muggle boy and a dental patient of Mr. and Mrs. Granger. During one appointment, he bit Mr. Granger, giving him a wound that required ten stitches to close. Hermione Granger related this story to Horace Slughorn, a wizard unfamiliar with the Muggle world, when he asked if dentistry was a dangerous profession.
