A removable retainer, also known as a loose retainer, is a dental appliance that is custom-made to fit the shape of the patient's mouth and teeth. It is typically made of plastic or a combination of plastic and metal wires. The purpose of a removable retainer is to maintain the position of the teeth after orthodontic treatment, such as braces, and prevent them from shifting back to their original position. Patients can take the retainer out for eating, brushing, and flossing, but it should be worn as directed by their orthodontist to ensure the best results. **
