Sweet tooth
Meaning
A strong liking or craving for sweet foods and desserts.
Origin
The phrase "sweet tooth" is a vivid personification of appetite, emerging in English around the 18th century. While the concept of a strong liking for sweet things is as old as sugar itself, the specific imagery of a "tooth" desiring something dates back even further, with expressions like having a "tooth for wine" signifying a strong liking. When "sweet" was combined with "tooth," it conjured a delightful image of one's very dental apparatus having an insatiable, almost independent, craving for sugary treats, compelling its owner towards cakes, candies, and confections. It's as if the mouth itself has a personality, leading the charge to the dessert table.
Examples
- My nephew has such a sweet tooth; he always goes straight for the dessert table.
- If you have a sweet tooth, this bakery's chocolate chip cookies are an absolute must-try.
