Following orthodontic treatment, teeth have a tendency to shift back towards their original positions. A retainer is a custom-made appliance designed to prevent this relapse. Its function is to hold the teeth in their corrected alignment, ensuring the long-term success of the orthodontic work. The consequences of neglecting to wear it vary depending on individual circumstances, the duration of time since the initial treatment, and the type of retainer prescribed.
Consistent use is crucial because bone and gum tissue require time to fully stabilize around newly aligned teeth. Retainers offer the benefit of maintaining the investment made in orthodontic treatment, preserving the achieved aesthetic and functional improvements. Historically, the understanding of post-orthodontic relapse has led to the development of various retainer designs, each aimed at providing optimal stabilization and minimizing tooth movement.
