What is the average age range for the eruption of the lower permanent central incisors?

• A. 3-4 years
• B. 6-7 years
• C. 9-11 years
• D. 12-13 years

Answer: (B)

The average age range for the eruption of the lower permanent central incisors is accurately identified as 6-7 years. During this developmental stage, children typically begin losing their primary teeth, and the eruption of the lower central incisors marks an important milestone in dental development. The emergence of these permanent teeth contributes to the transition from primary to permanent dentition, which is crucial for proper biting, chewing, and alignment of subsequent teeth. Understanding this timing helps dental professionals monitor children's dental growth and development, ensuring appropriate interventions if teeth do not erupt within the expected age range.
