The missing tooth is real

[GG - J]

Ed Helms, who plays Stu, has called The Hangover the most physically demanding movie he’s ever shot. He didn’t really lose his tooth, though. Helms never had an incisor grow in after losing his baby tooth, and he had his implant removed to shoot the movie.

I hope it was only the crown he had removed temporarily, not the actual implant (that would be an intense move).
