No. It's a fictional Simpsons book.

The book began as a joke in a TV cartoon. The dentist in the episode uses it as a scare tactic on a child patient, but that is a fictional scene. Later novelty products and a small self-published book borrow the name. There is no sign that dentists or orthodontists use any such book to push braces on American children.

• It first appears in The Simpsons season 4, episode 17, "Last Exit to Springfield".
• In the scene, Dr. Wolfe (a dentist) shows it to Ralph Wiggum to frighten him into taking care of his teeth, and Ralph is distressed.
• The gag plays on the American stereotype that British people have bad teeth.
• A 26-page paperback with the same title (Ulysses de Mise, CreateSpace) was published on July 20, 2017, as a novelty item.
• Merchandise such as notebooks based on the prop exists.

The claim mistakes a fictional television scene for a real dental practice. The episode does include a separate storyline about Lisa needing braces, but the book scene concerns Ralph's toothbrushing. The writers' account confirms the book's origin as a comedy invention.

• The book appears in “Last Exit to Springfield,” which first aired on March 11, 1993.
• Co-writer Jay Kogen credited Wallace Wolodarsky with creating the book gag.
• In the scene, Dr. Wolfe shows it to Ralph after Ralph admits he does not brush his teeth—not to persuade him to get braces.

The title comes from season 4, episode 17 of The Simpsons, where dentist Dr. Wolfe disciplines Ralph Wiggum for lying about brushing his teeth by forcing him to look through a photo album of severe dental misalignment (including a photo of then-Prince Charles). It was created purely for comedy to satirize American orthodontic culture and the stereotype of poor British teeth, and it does not exist as a real medical or educational text.

• The book originated in the 1993 Simpsons episode "Last Exit to Springfield".
• In the episode, dentist Dr. Wolfe uses the fictional photo book to terrify Ralph Wiggum into oral hygiene.
• The gag plays on an American cultural stereotype regarding British dental health.
• The animated prop even features a visible typo on its cover: "The Big Book of of British Smiles".
• No such publication exists or has ever been used in real-world pediatric dentistry.

The claim describes a fictional object from a cartoon as if it were a real clinical or parenting tool. The show's creators invented the book for a comedic scene about a dentist scaring a child into braces, and there is no record of such a book being produced, distributed or used by orthodontists. Because the object is fictional rather than merely unproven, the ordinary claim is straightforwardly false, and the surrounding evidence is not in dispute.

• The book appears in The Simpsons episode "Last Exit to Springfield," first aired on 11 February 1993, in Season 4.
• In the scene, a dentist uses the book, showing bad teeth, to convince Lisa Simpson to accept braces.
• The book was created as a joke prop by the show's writers; no real edition was used by dentists.
• The joke plays on the long-standing stereotype that British teeth are poor, a cliché that British dental-health data have increasingly contradicted.
• Any later novelty books or merchandise with a similar title were comedic tie-ins, not orthodontic scare materials.

The Big Book of British Smiles is a well-known joke from The Simpsons, an American animated series.

• The book is a joke referencing the American stereotype of British teeth.
