A dental retainer is an orthodontic device used to help maintain the position of teeth after braces or aligners have been removed. Its main purpose is to prevent teeth from shifting back to their original positions, which can naturally happen as the mouth adjusts. Retainers are typically custom-made to fit a person’s teeth and can be removable or fixed, depending on the patient’s needs and the orthodontist’s recommendation.

There are several types of retainers, including clear plastic retainers, wire-and-acrylic retainers, and fixed retainers that are bonded to the back of the teeth. Removable retainers are easy to clean and convenient to use, while fixed retainers provide constant support without relying on patient compliance. Wearing a retainer as directed is essential for preserving a straight smile and protecting the time and effort invested in orthodontic treatment.
