French is full of colorful expressions that don’t always have obvious meanings at first glance. One such expression is “avoir la dent dure”, which literally translates to “to have a hard tooth.” Its figurative meaning, however, is quite different.

Meaning and Origin of the Expression

The expression “avoir la dent dure” is used to describe someone who is highly critical, harsh in their judgments, or ruthless in their remarks. It applies to a person who does not mince their words and is particularly severe in their criticism, whether spoken or written.
