(名詞/通常用單數) 嗜鹹，對鹹食 (尤指薯條、洋芋片等) 的喜愛。相反詞：sweet tooth。
引句：
Would you always choose crisps over chocolate? You're not alone. While many of us may admit to a sweet tooth, more than 40 per cent of people have a weakness for salty rather than sugary flavours. Experts call this phenomenon a salt tooth, and it's becoming more common. For while some people are genetically programmed to crave salt, others are now developing a salt tooth as a result of the prevalence of highly processed, salty food in our diet.
