Childish Tooth Gap

Go To

"He is a protagonist with the hair of a Japanese anime and the tooth gap of every kid from recent Western Animation."

A character's dental state will often be used to show their personality in fiction. A young child will often have missing teeth, typically the upper front ones, if they are supposed to be sweet and energetic or innocent. It may also be used with children who have had their baby teeth replaced to showcase someone who is troublesome or reckless, to the point where they knocked out or otherwise lost their adult teeth. A gap between teeth (not due to a lack of teeth) may be used to make a character look more innocent or youthful.

Compare to Youthful Freckles, another design trait used to showcase a character's youth.

Truth in Television: Most kids lose their baby teeth between six and eight years, and probably won't have orthodontic work done to repair more permanent gaps until the early teens. And of course, anybody can get a tooth knocked out if they're not careful.

    Anime & Manga 
  • Subverted with Aiko from Goodnight Punpun. She is introduced as a little girl with missing front teeth. Punpun is instantly attracted to her and conjures up an image of her as a cute Manic Pixie Dream Girl. Aiko in reality is a Broken Bird, and it just gets worse as the manga continues. This is played darkly late into the series, where the now-adult Aiko gets a tooth knocked out which makes her look similar to how she did when introduced. Within fifteen chapters she's Driven to Suicide.
  • One Piece: Sabo in his younger years was shown with a missing tooth gap. While it might've been a naturally detaching milk tooth, the fact that he prefers to live in the streets may also contribute to that.
  • Child!Fuka is shown to be missing a tooth at the beginning of ViVid Strike! (it's implied that it got knocked out in a fight with some bullies). By the time the story proper starts, the gap is gone.
  • Josuke Higashikata from JoJo's Bizarre Adventure has a a distinct gap between his front top teeth which accentuate's his "innocent amnesiac" somewhat childish naivete to the world. One of his Fan Nicknames is "Gappy". The reason for the gap isn't merely orthodontic.
  • Heintz's Daddy's Girl daughter in Magnetic Rose is depicted with a gap in her teeth in flashbacks. It turns out they're flashbacks because Emily died at that age.

    Comic Books

    Films — Animation 

  • In Tales Of A Fourth Grade Nothing from Judy Blume's Fudge book series, Fudge, who at that point was only two years old, loses his two top front teeth when he falls off a jungle gym, pretending that he was a bird. His older brother Peter secretly calls him Fang, even though he never says it out loud because his mother doesn't like the nickname.
    • In an inversion of this trope, Peter remarks that the missing teeth make Fudge look like "a very small first grader", since Fudge is much younger than the usual age for losing teeth



    Video Games

  • In Tetrobot And Co, Maya has missing teeth in the photographs from her childhood.
  • The goofy and childish Rabbids from Raving Rabbids all have buck-teeth with gaps in them.
