Congenitally missing teeth most commonly includes which of the following?

• A. Premolars and canines
• B. Lateral incisors, second premolars, and third molars
• C. Incisors and molars
• D. First molars and second incisors

Answer: (B)

The most commonly congenitally missing teeth are indeed the lateral incisors, second premolars, and third molars. This phenomenon, known as hypodontia, is a relatively frequent dental condition where certain teeth fail to develop. The lateral incisors and second premolars are particularly notable because they are among the most commonly affected teeth in various studies and clinical observations. The third molars, or wisdom teeth, are also frequently absent due to their evolutionary redundancy, as many individuals simply do not have them develop.

While other teeth may also be congenitally missing, the specific combination of lateral incisors, second premolars, and third molars is recognized in pediatric dentistry as the most prevalent occurrence. Understanding this can aid clinicians in screening and managing potential orthodontic or prosthodontic issues that may arise from the absence of these specific teeth.
