Once you finish your orthodontic treatment, whether with traditional braces, clear aligners, or other procedures, your retainer is the key to holding it all together. But like any tool, it doesn’t last forever. Over time, these helpful oral appliances can wear out, lose their effectiveness, or even cause problems if not replaced. So, how often should you refresh your retainer? Continue reading to learn the signs that a potential swap could be in your future.
There Are Visible Cracks or Damage
One of the most obvious signs that it might be time for a new retainer is damage. Over time, cracks, chips, or broken wires can develop, especially if your retainer is dropped or exposed to heat too often.
A cracked or broken retainer won’t fit properly and may fail to hold your teeth in place, risking unwanted shifting. So, if you notice any damage, it’s time to visit your orthodontist and see if it’s time for a replacement.
The Retainer Fits Poorly
Your retainer should fit snugly over your teeth or rest comfortably against them if it’s a Hawley or permanent retainer. Over time, wear or shifting teeth can cause it to feel loose, tight, or even uncomfortable.
To make things worse, a poorly fitting retainer can’t keep your teeth in alignment and may actively irritate your gums. This is why if your retainer feels “off” or wiggly, you shouldn’t ignore it.
There’s a Bad Smell or Discoloration
Even if you clean your retainer regularly and do everything right, it can develop stains, discoloration, or odors that don’t go away. This is fairly common with older retainers, especially plastic ones. Over time, even the most well-cared-for appliance can accumulate bacteria and pigments that can make wearing it unpleasant. If your retainer starts to smell and you can’t seem to get it clean, it’s time for a new one!
Your Retainer Is Old
All retainers, even “permanent” ones, need replacements and repairs over time. Nothing lasts forever! Plastic appliances typically last 6 months to 2 years, while wire-and-acrylic ones can last 5-10 years. Permanent retainers can stay strong for up to 20 years but may still need repairs intermittently to keep them functional and comfortable.
If you’ve been holding on to your appliance past its prime, it might be time to make a switch.
Replacing your retainer as needed is key to keeping your teeth aligned and your smile straight. By watching for these signs, you can ensure your retainer is always up to the task. And when it’s time for your appliance to retire, your orthodontist can help you make a smooth transition for the sake of your smile.
