The Quick Answer

The correct plural of “tooth” is “teeth.” It’s that simple! But why isn’t it “tooths”? Well, that’s where things get interesting…

Why Do We Say “Teeth” Instead of “Tooths”?

You might be wondering why we don’t just add an “s” to tooth like we do with most English words. The answer takes us on a journey back through time! “Teeth” is what we call an irregular plural – it changes the middle of the word instead of adding something to the end.

This pattern comes from Old English, where many words changed their vowels to show they were plural. While most English words have simplified to just adding “s” or “es,” some of these old patterns stuck around. “Tooth/teeth” is part of a small family of words that still follow this ancient rule.

Other Words That Follow the Same Pattern

Here are some familiar words that change their vowels like “tooth/teeth”:

• Foot → Feet
• Goose → Geese
• Mouse → Mice
• Man → Men
• Woman → Women

Common Mistakes to Avoid

Mistake #1: Using “Tooths” Even though “tooths” might seem logical, it’s never correct in standard English. If you catch yourself writing “tooths,” remember that this word belongs to that special group that changes its vowel instead.

Mistake #2: Mixing Up Similar Words Sometimes people get confused with words that sound similar but follow different rules. For example:

• Booth → Booths (regular plural)
• Smooth → Smooths (regular plural)
• Truth → Truths (regular plural)
