If toothpaste is a substance used to clean all of a person’s teeth, then why isn’t it called teethpaste?

Therein lies the joke about toothpaste and broader observations about the irregularities of the English language that teethpaste highlights.

Joke, indeed. Early record of teethpaste can be found on internet Usenet forums as early as 1997. It’s a classist joke, one that makes fun of the South as backwoods. It goes: Why do you suppose that Arkansas invented toothpaste? If any other state did, it’d be called teethpaste! The punchline is that the people are so degenerate they only have one tooth.

So why is it toothpaste instead of teethpaste?

The short answer is that English is weird. The long answer is that compound words generally use the singular form of a word to represent the whole, including those involving body parts: hairbrushfootstool, armchair, bookcase, etc.

While we use toothpaste to brush more than one tooth, the English language has a logic all its own. This hasn’t stopped people, however, from continuing to troll dictionaries—or toothpaste manufacturers like Colgate—by playfully insisting, like @stephenjmolloy, that teethpaste is the correct term.

Who uses teethpaste?

Toothpaste, of course, is the standard word. The word teethpaste is generally only used when people consider why toothpaste isn’t called so, typically as a musing about the curiosities of English.

Instances of teethpaste often allude to @stephenjmolloy’s original statement: “It should be teethpaste and you know it.”
