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

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

Answer: (B)

Congenitally missing teeth tend to show a recognizable pattern: some tooth types are absent more often than others. In the ordering used here, the third tooth in frequency of absence is the third molar. This reflects how often these teeth fail to develop or fail to erupt in many individuals, likely due to late development and limited space in the jaw as it evolves. The maxillary lateral incisors and mandibular second premolars are typically more commonly missing than the third molars in this sequence, placing the third molars in the third position. So, the third molar is the third most likely to be congenitally absent according to this ranking.
