Clear plastic retainers are custom-made dental devices designed to help maintain the position of teeth after orthodontic treatment, such as braces. They are made from a thin, transparent material that fits snugly over the teeth, making them nearly invisible when worn. This discreet appearance allows individuals to continue their daily activities without feeling self-conscious about their smile. These retainers are typically worn at night or for a specified number of hours each day, depending on the orthodontist's recommendations. Regular use of clear plastic retainers can prevent teeth from shifting back to their original positions, ensuring that the results achieved with braces or other orthodontic treatments, like Invisalign, are preserved.
