Where do permanent premolars and molars tend to develop?

Explanation:
Permanent premolars and molars form from tooth buds that develop in the jaw within the space between the divergent roots of the deciduous teeth. That interradicular area becomes available as the roots of the primary teeth resorb in preparation for the eruption of the permanent teeth, so the developing germs lie posterior to the deciduous crowns and move into position as eruption proceeds. This explains why their development is associated with the space between the primary roots rather than in front of the deciduous crowns or in areas like the maxillary sinus.
