The Truth About Restarting with an Old Retainer


You've found your old retainer, perhaps tucked away in a drawer or a memory box. Maybe you're wondering if it's possible to start wearing it again. In this article, we'll explore the concept of using an old retainer, when it's a good idea, and when it might be best to consider alternatives.

1. Why Consider an Old Retainer?

There are a few reasons why you might contemplate using your old retainer:

  • Misplacement: You lost or misplaced your current retainer, and you're looking for a temporary solution.

  • Fit: Your old retainer still fits relatively well and provides some comfort.

  • Alignment Maintenance: You're looking to maintain the alignment of your teeth.

2. Check the Condition:

The first step is to carefully inspect the condition of your old retainer. Look for any signs of wear and tear, such as cracks, distortion, or broken wires. If the retainer is damaged, it's not advisable to use it.

3. Clean It Thoroughly:

Before considering reusing your old retainer, make sure it's cleaned thoroughly. Even if it was stored in a case, it's essential to remove any accumulated bacteria and debris.

4. Evaluate the Fit:

Try on your old retainer to see how it fits. It should feel snug but not overly tight. If it's too tight or uncomfortable, it's best not to use it. A poor fit can lead to issues or even dental pain.

5. How Long Has It Been?

Consider how long it's been since you last used the retainer. If it's been years, your teeth may have shifted to some extent. In this case, your old retainer might not be effective in maintaining alignment.

6. Consult Your Orthodontist:

If you're unsure about whether your old retainer is a viable option, it's a good idea to consult your orthodontist. They can assess your specific situation and offer guidance based on your dental history.

7. Temporary or Long-Term Solution?

Decide whether you're looking for a temporary or long-term solution. If you've misplaced your current retainer temporarily, using your old one until you can obtain a replacement might be fine. However, if you're considering long-term use, be cautious.

8. Watch for Changes:

Once you start wearing your old retainer again, pay close attention to any changes in your teeth or any discomfort. If you notice any adverse effects or shifts in your dental alignment, discontinue use and consult your orthodontist.

9. Explore Alternatives:

If your old retainer doesn't work well or causes issues, consider alternative solutions. Your orthodontist can provide guidance on new retainers or other options to maintain your teeth's alignment.


Reusing an old retainer can be a solution in certain circumstances, but it's not without its considerations. The key is to ensure that it's in good condition, fits well, and is used in consultation with your orthodontist. Your orthodontist can provide the best guidance on how to maintain your smile properly, whether through an old retainer or other options.
