Which teeth have two roots?

Root count varies among teeth, and recognizing which teeth are typically two-rooted helps in planning procedures like extractions and root canal work. In standard anatomy, the mandibular molars usually have two roots—one mesial and one distal. The maxillary first premolars commonly have two roots as well, often described as buccal and palatal. The other teeth listed don’t fit this pattern: central incisors and canines normally have a single root, and the maxillary first molar usually has three roots (two buccal and one palatal). So, the teeth that are commonly two-rooted are the mandibular molars and the maxillary first premolars.
