At what age does the permanent maxillary lateral incisors erupt
**Core Concept**
The eruption time of permanent teeth is an essential aspect of orthodontic and pediatric dentistry. The permanent maxillary lateral incisors are one of the primary teeth that erupt during childhood, and their timing is crucial for proper dental development.
**Why the Correct Answer is Right**
The permanent maxillary lateral incisors typically erupt between 8-12 years of age, with the average age being around 10 years. This timing is influenced by the overall development of the jaw and the gradual resorption of the primary teeth. As the primary canines and first molars erupt, there is sufficient space for the permanent lateral incisors to emerge. The eruption of these teeth is also associated with the development of the maxillary alveolar process, which provides the necessary support for the roots of the permanent teeth.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the permanent maxillary central incisors typically erupt before the lateral incisors, around 6-8 years of age.
**Option B:** This option is incorrect because the permanent maxillary canine teeth erupt after the lateral incisors, around 12-16 years of age.
**Option C:** This option is incorrect because the eruption time of the permanent maxillary lateral incisors is not before 6 years of age, as they require sufficient development of the jaw and primary tooth resorption.
**Clinical Pearl / High-Yield Fact**
The eruption time of permanent teeth can vary significantly among individuals, and a delay or premature eruption can be associated with various systemic and local factors, including nutritional deficiencies, genetic disorders, or trauma.
**Correct Answer:** C. 10 years.
