Definition: bite into

To bite, to eat something with appetite. Here, "beautiful teeth" does not refer to the aesthetic aspect of the teeth, but to their large size. In the past, this term was used to refer to canines, or the fangs found on carnivores. Since around the mid-15th century, the meaning of "pretty teeth" has remained, thus eliminating the more "cruel" connotation of beautiful teeth, which was found, for example, in the expression "to tear someone to pieces with beautiful teeth", meaning "to criticise them cruelly". Today, "mordre à belles dents" means to eat with great appetite.
