The primary purpose of orthodontic retainers is to maintain teeth in their corrected position after braces removal. Once braces are taken off, the teeth can be susceptible to shifting back to their original positions due to the natural forces acting on them and the elasticity of the surrounding periodontal structures. Retainers are designed to hold the teeth in their newly aligned positions, ensuring that the adjustments made during orthodontic treatment remain stable over time.

While other options may seem relevant, they do not accurately describe the function of retainers. Straightening teeth is a primary function of braces and not retainers. Preventing teeth from whitening is not a purpose of retainers, as whitening is unrelated to the retention process. Additionally, while healthy gums are important for overall dental health, retainers do not have a direct role in strengthening them. Retainers specifically focus on maintaining the alignment achieved during orthodontic treatment.
