On average, roughly how many permanent teeth would you expect a typical 9-year-old to already have erupted?
Show answer and explanation
Correct answer: B. Approximately 8–12 (the 4 permanent first molars and the 8 permanent incisors are typically erupted by this age, with canines/premolars usually following around age 10–12)
By around age 9, most children have their permanent first molars (erupting ~6 yrs) and all 8 permanent incisors (central and lateral, erupting ~6-8 yrs), totaling about 8–12 permanent teeth. Canines and premolars typically begin erupting closer to age 10-12, so counting them as 'already present' at 9 overestimates the typical timeline — always check current AAPD eruption charts, since there's natural variation.
