  White dwarf stars that enter the tidal radius of black holes with masses
$\lesssim$ $10^5$ M$_{\odot}$ are doomed to be ripped apart by tidal forces.
Black holes in this mass range between stellar black holes and supermassive
black holes have not been conclusively identified so the detection of a tidal
disruption of a white dwarf would provide clear evidence for the existence of
intermediate-mass black holes. In this review, we present a theoretical and
observational overview of the transient events that result from the tidal
disruptions of white dwarfs by intermediate-mass black holes. This includes
discussion of the latest simulations and predicted properties, the results of
observational searches, as well as a summary of the potential for gravitational
wave emission to be detected with upcoming missions.
