What is one major role of retention practices after orthodontic treatment?

Retention practices play a critical role in orthodontic treatment by maintaining the corrected position of teeth. After braces are removed or aligners are completed, the teeth may be prone to shifting back to their original positions due to the elastic and adaptive properties of the surrounding periodontal tissues. Retainers help hold the teeth in their new, corrected alignment while these tissues adjust to the changes made during treatment. Without proper retention, the benefits of orthodontic treatment might be lost as teeth can revert to their pre-treatment positions, thus negating the entire purpose of the corrective work done. Retention is essential for the long-term stability and success of the treatment outcomes, ensuring that the alignment achieved during active treatment is preserved.
