When is the usual eruption age for a lower central incisor?

• A. 4-5
• B. 5-6
• C. 6-7
• D. 7-8

Answer: (C)

The usual eruption age for a lower central incisor is around 6 to 7 years. During this time, children typically begin to experience the transition from primary teeth to permanent teeth. The lower central incisors are among the first permanent teeth to erupt, usually following the loss of their primary counterparts. This eruption is significant as it marks an important developmental milestone in dental health, indicating that the child is progressing into a new stage of dental maturity. The timing is generally consistent, although individual variations can occur due to factors like genetics and overall health. The knowledge of eruption timelines helps dental professionals in planning appropriate dental care and monitoring the oral development of children.
