Plus, why buck teeth are associated with different cartoon stereotypes
PDF download Download Article

Buck teeth are a fascinating character trope in media. On one hand, they’re associated with bumbling goofballs who never finished school, but on the other, they’re also supposed to be a sign that someone is a total nerd who never lifts their nose out of a book. In this article, we’re going to take a look at the most interesting and recognizable buck-toothed characters (and even take a look at where the stereotypes behind buck teeth come from).

SpongeBob (SpongeBob SquarePants)

PDF download Download Article
  1. Alongside his rectangular shape and absurdist love of kitchen work, SpongeBob’s buck teeth are probably his most defining characteristic. In fact, there’s even an entire episode surrounding the gap in his buck teeth being closed, which turns him into “CoolBob.”
    • SpongeBob’s buddy, Patrick, also has a single buck tooth. He didn’t make our list, though—the tooth isn’t prominent enough and only appears every once in a while.

Mater (Cars)

  1. When we embarked on this endeavor, none of us thought an automobile would be cracking the top of a list about teeth, but here we are. Tow Mater is the lovable rural rube who helps Lightning McQueen chase his dreams. His grill has a distinctly toothy smile that really helps round out his hillbilly character.
    • Why are buck teeth associated with rural characters? There’s a historical bias that medical care in the rural South isn’t as good as it is elsewhere. A lack of dental care has come to stand in as a symbol of a rural upbringing, but there’s no evidence Southerners actually have worse dental habits.[1]

Abby Mallard (Chicken Little)

PDF download Download Article
  1. Abby is a secondary character from 2005’s Chicken Little. She’s a fun-loving and supportive duck who later goes on to become Chicken Little’s girlfriend. She’s a lovable nerd with a cute, toothy smile that will melt your heart.
    • Why are buck teeth associated with nerdy characters? This is actually kind of a funny phenomenon. In evolutionary terms, you have to make up for physical shortcomings with intelligence. This is why geeks are often depicted with glasses, or viewed as unathletic—human beings instinctually associate lower physical traits with higher intellectual traits. The buck teeth are just an extension of that.[3]

Nigel (The Wild Thornberrys)

  1. Nigel is the patriarch of the Thornberry family, and boy, is his character design a lot to look at. He’s got a giant moustache, a huge honker, tiny, beady eyes, and buck teeth so shiny you could see your reflection in them. Oh, and he’s very British.
    • Why are buck teeth associated with the British? This comes from a widespread belief that the United Kingdom has worse dental care than the United States, so American media often depict British characters with less-than-ideal teeth. Weirdly enough, there is some truth to this one. Braces are much less common in England, while almost every American child gets them. On top of that, British health services don’t cover cosmetic dental stuff. So, Americans do tend to have straighter teeth on average.[4]

Kathy (Finding Nemo)

PDF download Download Article
  1. She’s definitely a minor character, but Kathy’s moments are so memorable that it’s hard not to include her. In the first film, she’s the character with the iconic line, "Oh, my gosh! Nemo's swimming out to sea!" In the sequel, she has a few scenes where she freaks out about Mr. Ray coming back from migration. Her character model is super interesting—she’s a narrow-faced triggerfish with two large teeth.[5]
    • Do fish have teeth? Yes! Most fish do have teeth, although they rarely look like human teeth. In fact, trigger fish are one of the only fish species this doesn’t apply to, and many of them look like they have buck teeth IRL!

Harold (Hey Arnold!)

PDF download Download Article
  1. Harold actually doesn’t technically have a buck tooth. By definition, buck teeth can only occur with the top teeth. But, he has this prominent tooth sticking out of his bottom jaw that kind of reads like a buck tooth. It’s interesting that just by moving the protruding tooth from the top to the bottom, the character goes from reading as “nerdy” to intimidating and scary; Harold is the oft-bully of the show.
