What Does a Retainer Do?
Once orthodontic treatment has moved your teeth into better alignment, they need help staying there. A retainer is an appliance, often a clear removable tray, that holds the teeth in their new position while the surrounding tissue settles. We plan the full sequence of treatment before it starts, and that includes what happens once the teeth are where they should be. Your dentist will talk you through how often to wear your retainer and how to look after it. Straighter teeth are also easier to keep clean, which helps protect against decay and gum problems long after treatment ends.
Living With a Retainer
Simple habits that help your retainer do its job.
- Wear as Directed A retainer only holds teeth while it is being worn, so follow the schedule your dentist sets.
- Keep It Clean Rinse it whenever you take it out and clean it the way your dentist shows you.
- Store It Safely Keep it in its case rather than a napkin, where it is easily lost or thrown away.
Bring It to Your Checkups
Bring your retainer to your routine visits so the fit can be checked. If it starts to feel tight or loose, or gets damaged, let us know rather than stopping wearing it.
