Which teeth have three roots?

Root morphology varies by tooth type, and maxillary molars commonly have three roots. The two buccal roots (mesial and distal) plus one palatal root anchor these teeth, giving strong support for their large chewing surface in the upper jaw. In contrast, mandibular molars usually have two roots, canine teeth typically have a single long root, and mandibular premolars are usually single-rooted (though some can have two). So the three-root pattern is most characteristic of the maxillary molars.
