Which arch can have teeth with three roots?

Explanation:
In upper teeth, especially the molars, you commonly see three roots—two buccal roots and one palatal root. This arrangement gives the large upper molars the stability they need to withstand chewing forces. Lower molars, in contrast, usually have two roots (mesial and distal) because the mandible’s anatomy doesn’t typically require a third root. So when thinking about teeth with three roots, the upper (maxillary) arch is the one that fits best.
