Start with a consistent daily cleaning routine and clean the case too. If odor returns immediately after a thorough clean, the retainer is cracked, rough, warped or no longer fits well, replacement can make more sense than repeatedly trying to rescue it.

At-home impression replacement if the old retainer is worn out.
Check Remi Clear Retainers- Rinse and clean the retainer daily rather than waiting for odor to appear.
- Clean the storage case regularly; a dirty case can re-contaminate a clean retainer.
- Avoid hot water on clear plastic retainers because heat can distort them.
Why retainers start to smell
Retainers sit against teeth for hours and collect the same plaque, saliva and food residue that builds up elsewhere in the mouth. When that film remains on the appliance, odor-producing bacteria can persist even if the retainer looks mostly clear.
How to get the smell out
Rinse the retainer with cool or lukewarm water, gently clean it according to the manufacturer or orthodontist instructions, and give it a deeper clean with a material-compatible tablet or ultrasonic cleaner. Clean and fully dry the case as well.
When cleaning is not enough
Persistent odor can be a sign that the surface has become rough, scratched or cracked enough to hold buildup. If the appliance is warped, damaged or no longer seats fully, ask an orthodontist or dentist whether it should be replaced.
If odor persists despite cleaning, or you also have mouth pain, sores, swelling or unusual taste, seek dental advice rather than assuming the appliance alone is the cause.
