When is the expected eruption age for the lower first molar?

• A. 5-6
• B. 6-7
• C. 7-8
• D. 8-9

Answer: (B)

The expected eruption age for the lower first molar is typically between 6 and 7 years. This timing is significant for tracking dental development in children. The lower first molars, also known as the mandibular first molars, are among the first permanent teeth to emerge, usually appearing shortly after the primary (deciduous) teeth begin to shed. The eruption of these molars plays a critical role in establishing the occlusion and overall alignment of the teeth. The timing aligns with the broader developmental milestones in children, where between ages 6 and 7, children often start to transition from primary to permanent teeth. Understanding this timeline is essential for dental professionals in monitoring dental development and identifying any potential issues early on. The age range of 6 to 7 years also corresponds with other significant dental events, such as the eruption of incisors, which provides important context for overall dental health and growth patterns in pediatric patients.
