At what age do mandibular second bicuspids typically erupt?

9-10
11-12
13-14
7-8

The correct answer is: 11-12

The mandibular second bicuspids, also known as mandibular second premolars, generally erupt between the ages of 11 and 12 years. This eruption timing is consistent with the dental development process that occurs during late childhood and early adolescence. At this age, children are typically transitioning from primary (baby) teeth to their permanent dentition, and the first premolars usually have already erupted prior to this timeframe. Knowing the typical eruption timelines is important for dental hygienists, as it assists in monitoring dental development in children and identifying any potential issues related to tooth eruption. Eruption patterns can sometimes vary among individuals, but this range is well-established in dental literature.
