Muroids are most closely related to the Dipodidae, a smaller group of rodents that includes the jerboas, birch mice, and jumping mice. [1] Jerboas have a dental formula of 1.0.0–1.3 1.0. 0.3 × 2 = 16–18, including incisors in the upper and lower jaws, three molars in the upper and lower jaw, and in most species a small premolar (the fourth upper premolar, P4) in the upper jaw only.

The teeth of newborn desert woodrats are initially splayed apart, creating a hexagonal opening between them, with which they clamp themselves to their mother's teats so firmly that they are difficult to separate.
