Is Your Retainer Failing You? Here’s Why It Might Be Time for a Replacement

Writer: Dr. Dorrin NilforoushanDr. Dorrin Nilforoushan

Did you know your retainer might not be doing its job anymore? If it’s over a year old, your retainer could be stretched, worn out, and harbouring bacteria—leaving your smile at risk.


Your Retainer Could Be Failing You – Here’s Why


Why Retainers Lose Effectiveness Over Time

Retainers are essential for maintaining your beautifully aligned smile after orthodontic treatment. But like any dental appliance, they don’t last forever. Over time, retainers can:

  • Stretch and weaken – reducing their ability to keep your teeth in place

  • Harbour harmful bacteria – which could affect your oral health

  • Become uncomfortable or ill-fitting – causing you to wear them less frequently

A worn-out retainer can lead to unwanted tooth movement, undoing the progress you worked so hard for.



Dr. Nilforoushan Weighs In

In this quick video, Dr. Nilforoushan explains why it's crucial to keep your retainer in top shape and how to know when it's time for a replacement. Don’t let a failing retainer compromise your smile!



When Should You Replace Your Retainer?

Most orthodontists recommend replacing your retainer every 1-2 years, depending on wear and tear. If your retainer feels loose, looks discoloured, or has an odour that won’t go away—even after cleaning—it’s time for an upgrade.
