5 Top Tips for Cleaning Retainers So They Last Longer
Once your braces come off, your retainers take over the important job of maintaining your new smile. Retainers are meant to be worn regularly, and with the proper care, they can last for many years. Keeping them clean and protected is one of the best ways to help them stay in good shape.
At Weaver Orthodontics, we want your retainers to feel comfortable and stay effective for as long as possible. While all retainers eventually need to be replaced, proper care can significantly extend their lifespan. Below, we cover simple, reliable ways to keep them clean and well-maintained.
Why Cleaning Your Retainer Matters
Cleaning your retainer involves more than a quick rinse. Just like teeth, retainers can collect plaque and bacteria over time. If this buildup isn’t removed, it can create an unpleasant taste or odor and may contribute to irritation or oral health issues.
Regular cleaning protects both your retainers and your smile. It also helps them stay clear, comfortable, and in good condition for longer.
Types of Retainers
Most patients wear their retainers full-time at first, then transition to wearing them mainly at night. With everyday use, keeping them clean becomes especially important. There are three common types of retainers:
Hawley Retainer
A traditional removable retainer with an acrylic base and thin metal wires. It is durable and easy to clean.
Essix Retainer
A clear, removable retainer that resembles clear aligners. These are convenient but can become cloudy if they are not cleaned properly.
Daily Cleaning vs. Occasional Deep Cleaning
Most patients benefit from gently rinsing and cleaning their removable retainers each day to prevent buildup. A deeper clean, such as a tablet soak, can be helpful a few times each week.
The proper routine varies by patient and by retainer type, so feel free to ask our team what may work best for you.
How Long Do Retainers Last?
Retainer lifespan varies based on the type and how they are cared for. In general:
Clear retainers may last 1–3 years
Hawley retainers may last 2–10 years
These timelines can vary from person to person. Regular cleaning and proper storage can help extend the lifespan of your retainers.
Best Ways to Clean Retainers
We often receive questions about the safest and most effective ways to clean retainers. Below are five methods that help keep them fresh and free of buildup.
1. Retainer Cleaning Tablets
Cleaning tablets explicitly designed for retainers or clear aligners can be found in most pharmacies and retail stores. These tablets gently remove buildup without scratching the material, especially for clear retainers.
If retainer cleaners are unavailable, denture tablets can be used occasionally. Choose formulas labeled as gentle and avoid those that advertise “scrubbing power,” which may contain abrasives that can damage clear retainers.
2. Distilled Vinegar Solution
A diluted vinegar soak can help loosen residue. Mix one part distilled vinegar with two parts warm (not hot) water. Soak removable retainers for 15–30 minutes, then rinse thoroughly before wearing.
A similar method can be used with baking soda. Mix one part baking soda with two parts warm water and soak for up to 30 minutes before rinsing.
For most cleaning methods, a short soak is usually enough. Extended soaking isn’t necessary and may affect certain retainer materials.
What to Avoid When Cleaning Retainers
A few habits can shorten a retainer's lifespan. We recommend avoiding:
Hot water, which can warp certain types of retainers
Harsh chemicals such as bleach or alcohol
Abrasive toothpaste on clear retainers
Scrubbing with firm-bristled brushes
If you’re ever unsure whether a cleaning method is right for your retainer type, our team is happy to help you choose an option that works well for your appliance.
When to Check Whether a Retainer Needs Replacement
Retainers naturally wear over time. Let us know if you notice:
Cracks or visible damage
Warping or changes in shape
A fit that feels unusually loose or tight
Difficulty keeping the retainer clean
Sometimes a minor adjustment is all that is needed. In other cases, a replacement may help keep your smile on track.
Don’t Forget to Bring Your Retainers to Appointments
Bringing your removable retainers to orthodontic check-ins allows us to confirm they are fitting properly and working as expected. This helps ensure your smile stays stable in the long term.
Frequently Asked Questions
How can I keep my retainers safe?
Always store removable retainers in their protective cases when not in use. A case helps prevent loss and keeps them out of reach of pets or small children. Bringing your case with you when you’re out is a simple way to avoid misplacing your retainers.
Can I leave my retainers in the car while I’m eating?
We do not recommend storing retainers anywhere that may become hot, such as inside a car, near a heater, or in hot water. Heat can cause the plastic in certain retainers to lose their shape.
What if my retainers still smell after cleaning?
A vinegar soak may help remove lingering odors. If buildup remains after consistent cleaning, it may be time to evaluate whether the retainers need to be replaced.
Can I use mouthwash to clean my retainers?
Most mouthwashes contain dyes that can stain retainers. For that reason, they are not recommended as a cleaning solution.
Can I brush my retainer with toothpaste?
Many toothpastes contain mild abrasives that may scratch removable retainers. We recommend using dish soap to clean your clear retainer.
