Which tooth is the fourth in the order of congenitally missing teeth?

• A. Maxillary second premolars
• B. Third molars
• C. Mandibular second premolars
• D. Maxillary lateral incisors

Answer: (A)

When teeth fail to develop congenitally, they follow a recognizable frequency pattern. The most commonly missing are the third molars, making them first in the order. The next most frequently missing are the maxillary lateral incisors, placing them second. Third in line are typically the mandibular second premolars. Therefore, the maxillary second premolars are fourth in the sequence of congenitally missing teeth. This ranking is commonly taught for exams, though exact frequencies can vary by population.
