At what age is root formation of the maxillary first molar (tooth #14) typically complete?

Maxillary first molars erupt around age 6-7 and complete their roots roughly 2-3 years later, near age 9-10. Crown calcification begins at birth, but full root formation is later.Other options: Birth is when crown calcification begins; ages 3-5 and 18 do not match first-molar root completion.Key exam takeaway: First permanent molars erupt ~6-7 years; roots finish ~9-10 years (about 2-3 years after eruption).
