While eating popcorn and watching TV, one of Mr. Bean's teeth gets broken, causing too much pain for him. After several attempts of pulling out his tooth, Bean eats one popcorn while he watches TV and the tooth finally comes out, but he makes a whistling sound every time he breathes through the gap in his mouth; he then uses a toy triceratops' horn as a tooth. When Bean looks horribly on his teeth on the next day, he decides to go to a dentist to have the tooth removed and repaired. When Bean tries to reattach the misplaced triceratops toy horn, he tries to remove the parts until he accidentally strikes his tooth, causing him pain once again.
