Yaeba [yah-ey-bah] is a term used to describe human teeth, especially upper canines, with an uncommonly fang-like appearance. In Japan it is perceived as a sign of youthfulness.

Cosmetic alterations to teeth have been practiced for centuries among many cultures throughout the world. In some cultures sharpening teeth is seen as a rite of passage for adolescents into adulthood.
