Looking up "Index of Teeth," there are no results for a mainstream movie. Could it be that the user confused the title with another one? Let me try some variations. There's a movie called "The Teeth That Bleed," which is a horror film. Maybe that's what they're referring to? The title "Index of Teeth" might be a mistranslation or mishearing of the original title. Alternatively, maybe it's a short film or an independent project that's not widely known.
