Congratulations on completing your orthodontic journey! Whether you’ve recently finished treatment with braces or clear aligners or have been wearing your retainers for years, knowing the best way to care for your retainer is imperative to preserve your new smile. Retainers help maintain the teeth in their corrected positions, preventing them from shifting back over time. However, simply wearing your retainer isn’t enough. Keeping it clean and well-maintained is vital for both oral health and the longevity of the appliance.
When retainers aren’t cleaned regularly, they can become a breeding ground for bacteria, plaque, and other debris. This leads to unpleasant odors, potential staining, and an increased risk of gum irritation or infection. A dirty retainer can also shorten the lifespan of the appliance, potentially causing it to warp or degrade its materials.
In this comprehensive guide, the American Association of Orthodontists (AAO) will walk you through everything you need to know about retainer care, from daily cleaning routines to troubleshooting common issues. By following these strategies, you’ll ensure that your smile stays beautiful and healthy for years to come, all while protecting the investment of time and money you’ve made in your orthodontic treatment.
Retainer Care at a Glance
Daily Care
- Rinse your retainer in lukewarm water each time you remove it. Avoid using hot water as it can damage your retainer.
- Brush your retainer with a dedicated toothbrush and dish soap every day. Avoid using toothpaste.
- Always use dish soap or special retainer cleaning aids to clean your retainer.
- For permanent retainers, floss and brush in between the wire and teeth every day
Long-Term Cleaning Tips:
- Use a retainer cleaning tablet or solution to remove bacteria and debris once per week for 10-20 minutes
- Submerge your retainer in a solution of one part hydrogen peroxide per water and soak for 15-20 minutes to remove stains and bacteria
- Invest in and use ultrasonic retainer cleaners and solutions to clean retainers in just a few minutes.
Why Do You Need to Clean Your Retainer?
Retainers do more than just keep your teeth in their corrected positions—they also become a constant part of your oral environment. Because they touch saliva, plaque, and any leftover food particles in your mouth, it’s important to clean them thoroughly and consistently. Failing to do so can affect both your oral health and the lifespan of the retainer itself.
Bacteria, Plaque, and Tartar Buildup
The moist environment of your retainer is the ideal place for bacteria to multiply. When not cleaned properly, these microorganisms can thrive and potentially contribute to bad breath, tooth decay, and gum inflammation. If the bacteria on your retainer and teeth aren’t regularly removed, they can begin to form a sticky film known as plaque. This substance clings to the tooth surfaces and to the retainer material.
When plaque sits on your teeth or retainer for extended periods, it can harden into tartar, which is far more difficult to remove. Tartar not only undermines oral hygiene efforts but can also irritate the gums and even damage your retainer over time.
Odors and Stains
Bacteria thrive on food particles and other organic matter, releasing unpleasant-smelling compounds. If you notice a persistent odor from your retainer, it’s often a sign that bacteria have multiplied unchecked. Retainers, especially clear plastic styles, can also develop noticeable stains from certain foods, drinks (like coffee or tea), and neglected oral hygiene. Discoloration is not just a cosmetic concern but can also signal a buildup of harmful substances like plaque.
Impact on Durability
Residual plaque, sugars, and acids from foods can gradually degrade acrylic or plastic retainers if left uncleaned. Over time, they might warp, crack, or lose their shape, compromising their effectiveness. This could require an early replacement, an unexpected expense. By keeping your retainer clean, you can extend its lifespan and maintain the best fit, potentially saving you money in the long run.
What Are The Common Retainer Care Mistakes and How Can I Avoid Them?
Even the most diligent retainer wearers can make unintentional errors that compromise the cleanliness, longevity, and effectiveness of their appliance. By learning to recognize and avoid these pitfalls, you’ll maintain a healthy retainer and enjoy a more comfortable overall experience.
- Using Hot or Boiling Water: Always use lukewarm water for rinsing, brushing, or soaking your retainer. High temperatures can warp or distort plastic retainers, potentially altering their fit. If the water feels too hot on your skin, it’s too hot for your retainer.
- Using Toothpaste with Abrasives or Whitening Agents: Many traditional toothpastes contain baking soda or other abrasive particles designed to scrub tooth enamel. While these may be beneficial for natural teeth, they can leave tiny scratches on your retainer’s surface, leading to discoloration or bacterial buildup. Instead, opt for retainer-friendly cleaning products like mild dish soap or specialized retainer cleansers.
- Skipping Daily Rinses: While it may seem like a small concession, not rinsing your retainer daily allows saliva, plaque, and food particles to dry on the retainer, making it harder to remove and creating a hospitable environment for bacterial growth. Make a habit of rinsing your retainer under lukewarm water as soon as you remove it. Even a quick 10-second rinse goes a long way toward preventing buildup.
- Using Bleach or Other Harsh Chemicals: Substances like bleach, alcohol-based mouthwash, and strong detergents can degrade retainer materials or leave harmful residues. These chemicals can also irritate your mouth and gums. Stick to gentle cleansers formulated specifically for oral appliances. If you’re unsure about a particular product, consult your AAO orthodontist before using it on your retainer.
- Neglecting Permanent Retainer Care: The wire in a fixed retainer can easily trap plaque and debris. Over time, this may contribute to tooth decay, gum inflammation, and unpleasant odors. Using floss threaders, interdental brushes, or a water flosser to clean around the fixed wire and under the gum line can help reduce this risk.
When Should I Call My Orthodontist About Retainer Issues?
Even with a solid cleaning regimen, you may encounter occasional issues with your retainer, some of which require professional attention. Staying aware of changes in your retainer’s appearance, smell, or fit can prevent small problems from turning into bigger, more expensive ones. Here are some common issues that call for an orthodontist’s help.
Persistent Odors or Discoloration
Sometimes, despite regular cleaning, a retainer can develop an ongoing unpleasant smell or noticeable stains. This can result from resistant bacteria, the retainer’s material aging, or overlooked buildup.
Before reaching out to your orthodontist, try a stronger or more frequent deep-cleaning method, such as a retainer-cleaning tablet or a baking soda paste. If odors or discoloration persist after trying multiple cleaning methods, schedule an appointment with your orthodontist. Your retainer may have microscopic cracks or other damage that allows bacteria to linger.
Cracks, Warping, or Loose Wires
Retainers, especially clear plastic ones, can become warped from exposure to heat or physical force. Hawley retainers or bonded wires can bend or break under excessive stress. Cracks and loose wiring can both compromise the retainer’s effectiveness.
If you notice cracks or loose wires, stop wearing your retainer immediately. Continuing to wear a warped or broken retainer can shift your teeth improperly or irritate your mouth. If you have a backup retainer, wear it in the meantime to prevent relapse. For any visible damage—especially if the fit feels off—contact your orthodontist. They can evaluate whether the retainer can be repaired or if a replacement is necessary.
Irritation or Gum Sensitivity
Rough edges, bacterial buildup, or ill-fitting wires can cause your cheeks, gums, or tongue to feel sore. In other cases, the gum tissue may become inflamed due to poor hygiene around a fixed retainer.
Irritation could be a sign that it’s time to review your cleaning routine. Improper or infrequent cleaning can lead to irritation from bacteria and plaque, so make sure you’re covering all areas of the retainer thoroughly in your daily cleaning. If a sharp wire or edge is digging into your gum or cheek, wax can provide temporary relief, but if you feel persistent discomfort, reach out to your orthodontist for an appointment.
Retainer Fit Changes
A retainer that once fit snugly may start feeling tight or loose, which can occur if the retainer warps, if you’ve worn it inconsistently, or if your teeth are shifting slightly. If there’s space between the retainer and your teeth, or if it feels overly tight in certain spots, the fit has likely changed.
Sometimes wearing the retainer more consistently can help. Minor adjustments might fix slight misalignments if caught early. If the retainer doesn’t return to a comfortable fit within a day or two, or if you’re experiencing pain, it’s time for a professional evaluation. You may need a new impression for a replacement or an adjustment to your current appliance.
