What is the most important reason for performing orthodontic treatment on a patient?

Performing orthodontic treatment primarily aims to ensure proper tooth movement and spacing, which is fundamental to achieving optimal dental alignment and occlusion. Proper alignment of teeth not only enhances the function of the bite but also contributes to long-term oral health. With correctly aligned teeth, there is a lower incidence of abnormal wear, tooth fractures, and issues related to the jaw, such as temporomandibular joint disorders.

Additionally, when teeth are well-positioned, they can be cleaned more effectively, contributing to better oral hygiene and reducing the likelihood of dental problems, including periodontal disease. While improving aesthetics, enhancing speech clarity, and reducing the risk of periodontal disease are also important considerations in orthodontics, they often stem from the foundational goal of ensuring proper tooth movement and spacing. Without effective management of this primary concern, the other benefits may not be fully realized.
