How to Clean Retainers: Tips for a Sparkling Smile


Your retainer is an essential tool in maintaining your teeth alignment post orthodontic treatment. Whether you wore braces or clear aligners, retainers play a crucial role in keeping your teeth in their new position while the gums and bone settle. This phase is crucial to prevent your teeth from shifting back to their original misaligned state.

There are several types of retainers, including the commonly used Hawley and ESSIX retainers, as well as permanent retainers. Each type requires specific cleaning methods to ensure optimal hygiene and longevity.

Whether you’re new to wearing a retainer or have been using one for years, this guide will be beneficial in maintaining its cleanliness and effectiveness. Following these tips will not only give you a sparkling smile but also safeguard your oral health.

The Importance of Proper Retainer Care

  1. Preserving Teeth Alignment: After orthodontic treatment, your teeth need time to adapt to their new positions. Retainers help ensure that your teeth stay in place and don’t move back to their original position. Wearing your retainer as directed by your orthodontist is crucial for maintaining the results achieved through months or even years of treatment.
  2. Preventing Dental Problems: Dirty retainers can harbour bacteria and plaque, leading to cavities and gum disease. Cleaning your retainers regularly is not only important for their effectiveness but also for your overall oral health.

The Risks of Neglecting Retainer Care

When you put on a dirty retainer, it’s like wearing an unwashed piece of clothing in your mouth. Any bacteria, food particles, or debris that get trapped under the retainer can remain there and multiply if not cleaned properly. This can result in:

  • Bad breath
  • Increased risk of tooth decay
  • Gum inflammation and infection

Regularly cleaning your retainer helps remove these harmful substances before they cause any issues. It also keeps your breath fresh and ensures that wearing your retainer remains comfortable.

How to Take Care of Your Removable Retainers

Here are some essential tips for maintaining your retainers:

  1. Follow Your Orthodontist’s Instructions: Wear your retainers according to the schedule provided by your orthodontist. Whether it’s full-time initially or only at night, consistency is key.
  2. Remove Your Retainer When Eating: Take out your retainers before meals to prevent food particles from getting trapped.
  3. Clean Your Retainer Daily: Use a soft toothbrush and non-abrasive toothpaste to gently brush your retainers. Rinse it thoroughly with water afterward.
  4. Soak Your Retainer Regularly: Soaking your retainers in a denture cleaner or a mixture of water and mild dish soap can help remove stubborn stains and bacteria.
  5. Store Your Retainer Properly: When you’re not wearing your retainers, keep it in its case to protect it from damage and prevent loss.

In summary, taking care of your retainers is just as important as practicing good oral hygiene. By making cleaning a part of your daily routine and following proper maintenance habits, you can ensure the longevity of your retainers and the health of your smile.

Cleaning Tips for Permanent Retainers

Permanent retainers can be challenging to clean because they are fixed in place. However, you can still maintain good hygiene with the right approach. Here are some tips:

Brushing Techniques

  1. Use a soft-bristled toothbrush and non-abrasive toothpaste for effective cleaning.
  2. Angle the bristles towards the gum line to clean the retainer wire and teeth properly.
  3. Brush back and forth along the wire and all around each tooth attached to the wire.

Flossing Techniques

Flossing permanent retainers may seem tricky, but using specialized dental tools can make it simpler:

  1. Floss Threaders: This tool helps you thread floss beneath the wire of your permanent retainer. Once threaded, you can floss as you would normally do.
  2. Interdental Brushes: These are small brushes designed to clean between your teeth. They work excellently for cleaning around permanent retention wires.

Remember, regular flossing is crucial in preventing plaque buildup and gum disease.

Professional Cleanings

While home care is essential, regular professional cleanings ensure any hard-to-reach areas are thoroughly cleaned. Consult with your dental professional on how often these cleanings should occur based on your oral health condition.

Cleaning permanent retainers does require a bit more effort than removable ones, but with these tips in mind, it becomes a manageable part of your daily oral care routine.

Maintaining a Hygienic Retainer Case

Retainer case hygiene is crucial yet often neglected. These cases harbour bacteria and debris if not cleaned regularly, potentially compromising oral health. Here are simple steps to ensure your retainer case remains hygienic:

  1. Rinse Daily: After removing your retainer, rinse the case with warm water to dislodge any loose particles.
  2. Soap Wash: Clean the case with mild dish soap at least once a week to remove buildup. Use a soft brush to reach into crevices.
  3. Air Dry: Allow the case to air dry completely before placing your retainer back in; this prevents bacterial growth.
  4. Avoid Harsh Chemicals: Steer clear of abrasive cleaners or disinfectant wipes that can damage the case and leave harmful residues.
  5. Regular Replacement: Replace your retainer case every six months, or sooner if it shows signs of wear or has an odour.


Retainer cleaning tips are essential for anyone looking to preserve their orthodontic results and maintain a sparkling smile. By diligently following the guidelines for brushing, soaking, and caring for your retainers, you protect not only the alignment of your teeth but also your overall oral health. Remember that a clean retainer is as important as the retainer itself in keeping your smile radiant and healthy. Embrace these practices, commit to regular cleaning, and watch as your smile continues to shine day after day.
