Congenital anomaly in number of teeth

Last edited: 4/15/2026

Overview

Congenital anomalies in the number of teeth, also known as tooth agenesis or hyperdontia, refer to the presence or absence of teeth at birth beyond typical variations, impacting dental development and function 1.

Diagnosis

  • Clinical examination by a pediatric dentist or orthodontist to assess tooth presence and alignment 1.
  • Radiographic imaging (e.g., panoramic X-rays) to confirm the number and position of teeth 1.
  • Genetic testing may be considered in cases suggestive of hereditary patterns 1.

    • Management

  • Orthodontic intervention for alignment issues caused by missing or extra teeth 1.
  • Prosthetic options (e.g., dentures, bridges) for functional and aesthetic restoration in cases of significant tooth agenesis 1.
  • Regular dental follow-ups to monitor development and intervene early for complications 1.

    • Special Populations

  • Pregnancy: No specific guidance provided in the abstract 1.
  • Pediatrics: Early intervention by pediatric dentists crucial for addressing developmental issues 1.
  • Elderly: Management focuses on maintaining oral health and addressing complications related to existing anomalies 1.
  • Comorbidities: No specific information provided regarding comorbidities in relation to tooth anomalies 1.

    • Key Recommendations

  • Conduct a thorough clinical examination and radiographic assessment for diagnosis of congenital tooth anomalies 1 (Evidence: Expert opinion).
  • Implement orthodontic or prosthetic treatments based on individual dental needs to ensure proper function and aesthetics 1 (Evidence: Expert opinion).
  • Schedule regular dental evaluations during childhood to monitor development and manage complications proactively 1 (Evidence: Expert opinion).
