Question: 1 / 400

What is the typical eruption age for lower permanent central incisors?

4 - 5 years

5 - 6 years

6 - 7 years

The typical eruption age for lower permanent central incisors is around 6 to 7 years. Understanding dental development is crucial for dental professionals as it helps in monitoring growth and diagnosing potential issues.

During this period, children typically transition from their primary teeth to permanent teeth, and the lower central incisors are among the first permanent teeth to erupt. This eruption timeframe aligns with the growth patterns seen in children, where the primary teeth subsequently become loose and are replaced by permanent ones.

Awareness of the eruption timeline aids in ensuring that children receive proper dental care and interventions if their tooth development does not follow the expected sequence.
