What is the typical sequence of primary tooth eruption?

• A. Generally central incisors first, followed by lateral incisors, first molars, canines, and second molars; exact order can vary.
• B. Molars first, then incisors, then canines.
• C. Canines first, then incisors, then molars.
• D. First molars first, then canines, then incisors.

Answer: (A)

The typical primary eruption pattern starts with the incisors, with the central incisors coming in before the lateral incisors. After the incisors, the first molars appear, then the canines, and finally the second molars. This front-to-back sequence reflects how tooth germs develop and erupt over time, so anterior teeth crown and root formation reach the eruption stage earlier than posterior teeth. There can be some variation in the exact timing and slight differences between upper and lower jaws, but this overall order is the most consistently observed in children.
