In the mandible, what is the typical direction of the shedding sequence?

Explanation:
The direction of shedding is driven by the eruption order of the permanent teeth and the resorption of the roots of the deciduous teeth they replace. In the mandible, permanent incisors erupt before the canines and molars, so the resorption starts at the front and moves toward the back. As each anterior deciduous tooth loses its root due to the erupting permanent tooth beneath it, it loosens and sheds, and this process continues posteriorly. That front-to-back pattern is typical for the lower jaw, whereas the upper jaw often shows a different direction.
