Most dentist ads show people with perfect teeth. Boring. This one hits differently. Horizon Dental Care used a close-up of glossy red lips with one missing tooth and a cheeky line: “What’s Mithing Here?”
Why this billboard works
It breaks the pattern. Viewers expect smiles, not flaws.
The “Mithing” typo instantly makes people pause and think.
It uses curiosity like a hook — your brain wants to fill the gap.
The bright lips focus attention right where the problem (and solution) is.
Real-world examples of curiosity-driven ads
Spotify’s “2018 Goals” ads used user data quirks to make people laugh and look twice.
Snickers’ “You’re not you when you’re hungry” plays on humor and imperfection.
The Economist’s clever, cryptic billboards (“Great minds like a challenge”) trigger curiosity and self-identification.
