a liking or craving for candy and other sweets. A love for sugary foods, as in You can always please Nell with cake or ice cream; she has a big sweet tooth . This expression dates from the late 1300s, although it then referred not only to sweets but other delicacies as well.

“Sweet tooth” is a common term we use in English to describe someone’s hankering for sweet foods or if they have a strong craving for sugary treats when they don’t normally eat sweet things. It’s mostly used in an informal context and has no literal meaning.
