Patients undergoing some form of orthodontic treatment can expect to have a retainer, with the end of their alignment journey involving being fitted for a retainer. Every patient will receive a retainer, as it’s a necessary step after realigning the teeth.
What does a retainer do?
A retainer is used to help preserve the new alignment, into which the teeth have been carefully guided. Our teeth after orthodontic treatment can be prone to moving back into their natural positions. When this happens, we call it a dental relapse.
Your orthodontist will typically recommend one of two types of retainers: fixed and removable retainers. Each retainer performs slightly differently; fixed retainers are adhered to the back of the teeth and are permanent. Removable retainers on the other hand are often a plastic or metal appliance which can be inserted and removed at any given point.
The importance of wearing your retainer.
An orthodontic relapse occurs when the retainer isn’t worn as frequently as needed to preserve the new positioning of the teeth. As we age, our mouth naturally changes, causing the teeth to gradually shift. Using your retainer will help prevent the teeth from moving out of alignment.
Because of this, retainers are used long-term. Right after treatment, they need to be worn frequently. After a few years, patients will be able to reduce the amount they wear the retainer, limiting the wear time to while they’re sleeping, eventually to the point of wearing it every other night.
How often should I clean my retainer?
How you care for your retainer will entirely depend upon the type you have; each requires a slightly different strategy to ensure they’re clean.
Removable Retainers
Removable retainers can be cleaned using a soft-bristle toothbrush daily. Try to avoid using a toothpaste against a plastic retainer as it can dull the surface. Instead, use warm water, or a recommended retainer cleaning solution.
Store your removable retainer in a dry protective case and always take it out before eating or drinking.
Fixed Retainers
Fixed retainers are known for being slightly harder to clean, as they’re adhered to the back of the teeth. Your orthodontist will demonstrate the techniques needed to properly clean the teeth and retainer.
You’ll be shown different cleaning tools like wire floss, interdental brushes, and mouthwashes. It’s important that if you spot any signs of the retainer detaching, you’ll need to see your orthodontist to have it fixed.
Wearing a retainer is a simple yet essential step in protecting the effort, time and investment you’ve made in your aligned smile. Follow your orthodontist’s guidance and maintain your retainer for long-lasting positive results.
