The Hawley retainer is the most widely used option. It consists of a slim, contoured acrylic base shaped to fit the roof of your mouth, along with a metal wire that keeps your teeth in their corrected positions. Durable and easy to take in and out, the Hawley retainer also offers a fun personalization element — you can pick from a variety of colors and patterns for the acrylic portion. Minor tooth adjustments can also be made to it over time if needed.
A widely used alternative is the clear aligner-style retainer, which closely resembles the Invisalign® tray system. Crafted from thin, see-through plastic and molded precisely to your teeth, these retainers offer a virtually undetectable appearance with no visible wire. They are just as easy to remove, though they tend to be slightly less robust than Hawley retainers. This style may not be appropriate for patients with certain issues, such as bruxism (teeth grinding).
For certain patients, a fixed retainer may be the best choice, particularly for the lower front teeth. True to their name, these retainers cannot be removed by the patient — but they also cannot be seen. Similar in concept to lingual braces, a fixed retainer uses a wire that is bonded directly to the back (tongue-facing) side of the teeth. It may stay in place for several months or considerably longer. This option is often recommended when there is a significant likelihood of teeth drifting back to their previous positions.
