When is the usual age for the eruption of an upper lateral incisor?

The eruption of the upper lateral incisor typically occurs between the ages of 8 to 9 years. This timing is consistent with the overall chronological development of a child's dentition, where the permanent teeth generally emerge following a predictable sequence.

The upper central incisors usually erupt first, followed by the lateral incisors. When children reach about 8 years of age, the development of their dental arches allows for the eruption of the upper lateral incisors. This age range is based on dental development charts, which outline the average ages for all primary and permanent teeth to emerge.

Understanding this sequence is crucial for dental professionals, as it helps in monitoring a child's dental development and in diagnosing any potential issues with eruption patterns that may need to be addressed.
