Retainers play a crucial role in maintaining your straightened smile after orthodontic treatment. But like anything else, they don’t last forever. So, how often should retainers be replaced? Let’s dive in.
Our Canadian dental team wants to help you keep your smile looking its best. Here’s what you need to know about retainer longevity and when it’s time for a new one.
🦷 When Should You Replace Your Retainer?
The lifespan of your retainer depends on its type and how well you care for it. Your orthodontist will recommend how often you should replace it based on your unique needs.
General guidelines for retainer longevity:
- Hawley (wire and acrylic) retainers – Last about 5–10 years with proper care.
- Clear plastic retainers (Essix or Vivera) – Typically last 6 months to a few years.
- Fixed (bonded) retainers – Can last many years but may require adjustments.
Signs Your Retainer Needs Replacing
Even with excellent care, retainers wear out over time. Here are some signs you may need a new one:
- Cracks, holes, or thinning material
- Loose fit or shifting teeth
- Persistent bad odour or discolouration
- Broken wires (for Hawley or fixed retainers)
A worn-out or ill-fitting retainer won’t keep your teeth in place properly. If you notice these issues, schedule an appointment.
💼 What Should You Do?
If you’re unsure whether your retainer needs replacing, the best step is to visit your orthodontist. Regular checkups can help ensure your retainer is in good shape and doing its job.
Pro tip: To extend your retainer’s lifespan, clean it regularly, store it in its case when not in use, and avoid exposing it to heat or chemicals.
