If you put in the effort and time straightening out your teeth, the last thing you want is to end up with an unkempt, unpleasant-smelling, or deformed Invisalign retainer. A lot of our patients from the Bryn Mawr area and Main Line feel confused about how to properly clean their Invisalign retainers, and in some cases, may be accidentally harming them without knowing it. The bright side? Cleaning your Invisalign is easy once you learn how and what not to do!
At Dillon Family Dentistry, we help local patients protect their results long after Invisalign treatment ends. Here’s how to keep your retainers clean, clear, and comfortable every day.
Why Cleaning Your Invisalign Retainer Matters
For a long time, retainers work as a storage unit for your mouth. If you do not regularly take care of your retainer, it will accumulate plaque, bacteria, and also smell bad (just like your teeth). Retainers that are not cleaned properly will wear out more quickly than ones that are maintained. If your retainer wears down, whether from being dirty or just from being used for too long, it could break, stain or need to be replaced before you plan to replace it.
Clean retainers help:
- Keep your breath fresh
- Prevent bacteria buildup
- Protect your teeth and gums
- Maintain a clear, nearly invisible look
For patients in the Main Line who wear retainers daily or nightly, cleaning isn’t optional; it’s essential.
How to Clean an Invisalign Retainer the Right Way
Rinse Every Time You Remove It
Ensure that every time you remove your Invisalign retainer, you rinse it under lukewarm water. This very basic step prevents saliva and plaque from adhering to the surface of the retainers when they dry.
Do not use hot water because it will cause distortion to the retainers and could alter their fit.
Brush Gently Once a Day
To carefully clean your retainer, use a gentle, soft-bristle toothbrush with clear liquid soap. One of our best retainer cleaning recommendations! Toothpaste should be avoided because most toothpaste contains abrasives that may scratch the plastic and allow bacteria to attach to the surface easily.
Soak Regularly
A daily soak, or even every other day, can help eliminate retainer odor. Use cleaning crystals or soaking solutions approved by Invisalign to help maintain your retainer. Soaking will eliminate bacteria that cannot be removed by simply brushing and helps keep your aligners clearer and fresher.
Store It Properly
When you’re not wearing your retainer, keep it in its protective case. Leaving it out exposes it to bacteria or worse, accidental damage or pets.

Common Invisalign Hygiene Mistakes to Avoid
Even well-meaning patients make these mistakes:
- Using hot or boiling water
- Cleaning with vinegar or harsh chemicals
- Scrubbing too hard
- Wrapping retainers in napkins (they often get thrown away)
These habits can weaken the material and shorten the life of your Invisalign retainers.
How Long Do Invisalign Retainers Last?
A properly taken care of retainer can last for many years, but over time, the retainer can wear down and become damaged due to normal wear-and-tear, grinding, or improper cleaning habits. When this occurs, it is important to get a new retainer as soon as possible so that your teeth do not shift out of place.
If your retainer is feeling loose, cloudy, or smelling after being cleaned, you should discuss the possibility of replacing your Invisalign with your dentist as soon as possible.
Frequently Asked Questions About Invisalign Retainers
- Can I use mouthwash to clean my retainer?
Alcohol-based mouthwashes can damage the plastic. If you choose to use mouthwash, make sure it’s alcohol-free and diluted.
- Is it okay to clean retainers less often if I only wear them at night?
No. Night-only wear still allows bacteria to build up. Daily cleaning is always recommended.
- What if my retainer already smells?
A deep soak using a professional retainer cleaner usually helps. If odor persists, contact your dentist; it may be time for a replacement.
