What to Do If Your Retainer Cracks or Breaks
Feb 1, 2026 · 14 min read
Don't panic — but don't ignore it either. Here's exactly what to do next, whether it's safe to keep wearing, and how to prevent it.
The Quick Answer: If your retainer just cracked or broke, stop wearing it if the crack is large, the retainer has split, or there are sharp edges. A small surface crack with no sharp edges may be worn temporarily (1–2 days maximum) while you contact your orthodontist. Call your orthodontist or dentist as soon as possible — ideally the same day. Save all pieces and bring them to your appointment. Do not attempt DIY repairs with super glue or household adhesives.
Your teeth can begin shifting within days without proper retention. A quick replacement is far cheaper than the orthodontic retreatment you could face if you wait too long. When it's time to replace, consider upgrading to a retainer built from more crack-resistant material — like the Superb Retainer, made from Zendura A.
You're brushing your teeth before bed and pick up your retainer — and there it is. A crack running across the plastic. Or maybe it happened in your mouth: a sudden snap while you were eating something you shouldn't have been. Or you dropped it on the bathroom tile and it split in two.
However it happened, the question is the same: "Is this still safe to wear? What do I do now?"
A cracked or broken retainer is not an orthodontic emergency — but it is something that needs to be addressed quickly. The longer you go without effective retention, the more your teeth can shift. And a cracked retainer that seems "fine" can actually be doing more harm than good.
Here's everything you need to know — from immediate next steps to long-term prevention.
A Note on Cleaning Damage
Using the wrong cleaning products can silently weaken your retainer over time. Avoid bleach, alcohol, abrasive toothpaste, and baking soda — these create micro-scratches on the plastic surface that weaken the material and harbor bacteria. Stick to a soft-bristle brush with mild dish soap for daily cleaning, and a retainer-specific cleaning tablet for weekly deep cleaning.
