How to use "a sweet tooth"

What Does "a sweet tooth" Mean?

• The idiomatic meaning of "a sweet tooth" is a strong liking or craving for sugary foods, such as candy, pastries, and desserts. It describes a fondness for sweet tastes, not a literal tooth.
• The origin isn't definitively known, but it's likely a metaphorical extension of the idea that one's "tooth" (taste, appetite) is inclined towards sweetness.
• Register: neutral

How to Use It

• "A sweet tooth" is typically used as a noun phrase, often in the context of saying someone has a sweet tooth. It can be modified (e.g., "a terrible sweet tooth") and can be negated (e.g., "I don't have a sweet tooth"). It can be used in questions (e.g., "Do you have a sweet tooth?").
• It sounds unnatural to use it in a purely literal sense (e.g., describing a tooth made of something sweet). Overly formal or technical contexts might call for a more precise description of dietary preferences.
