Orthodontic Considerations For Tooth Agenesis : A Narrative Review

AbstractTooth agenesis is one of the most prevalent dental developmental anomalies, commonly affecting the upper front teeth and both upper and lower premolars. Its causes are complex and include a mix of genetic, environmental, and epigenetic influences. This condition may be associated with syndromes such as ectodermal dysplasia or may occur in non-syndromic familial patterns. The absence of teeth can significantly impact bite alignment, appearance, chewing efficiency, and emotional well being.Managing tooth agenesis orthodontically demands a team based approach that integrates accurate diagnosis, strategic treatment planning, and coordination with restorative and prosthodontic specialists. Clinical choices are guided by factors such as the number and position of missing teeth, the patient's age, growth stage, and the health of surrounding teeth.Treatment may involve either closing the spaces through orthodontic tooth movement or opening spaces to accommodate future prosthetic solutions like implants, bridges, or dentures.For younger patients who are still growing, temporary space maintainers may be used until they are ready for permanent treatment. A collaborative, interdisciplinary strategy is key to achieving optimal function and aesthetics. Detecting the condition early and initiating timely care is vital to reduce complications and ensure proper dental and facial development.Keywords: Genetics, Orthodontic space management, Tooth agenesis
