At what age does calcification of tooth #14 (maxillary 1st premolar) begin?

  1. At birth
  2. 6-7 years
  3. 3-5 years (maxillary 1st premolar begins calcification at ~3-4 years)
  4. 10-12 years
Show answer and explanation

Correct answer: C. 3-5 years (maxillary 1st premolar begins calcification at ~3-4 years)

  • A. Premolars do not begin calcification at birth; this timeline applies more to primary teeth/first molars.
  • B. 6-7 years is closer to the eruption timing of first permanent molars/incisors, not premolar calcification onset.
  • C. Correct. The maxillary first premolar begins calcification at approximately 3-4 years of age (commonly cited range 3-5 years).
  • D. 10-12 years is too late; premolar calcification begins years earlier.
