Finishing your braces journey doesn’t mean your orthodontic treatment is over. In fact, once the brackets come off and the aligners are put away, the next step is just as important: keeping your teeth in place.
That’s where retainers come in. Without them, teeth can slowly drift back to their old positions over time — undoing the months (or years) of effort you’ve already put in.
But with different types of retainers available, and each requiring proper care, it’s important to know which option might be best for you — and how to clean it the right way.
Who Needs Retainers?
Retainers are custom-made to hold your teeth in their corrected positions after orthodontic treatment. This is because whether you’ve had braces or clear aligners, your teeth need time to stabilise in their new alignment. And even then, they may still shift gradually over the years — especially without the right support.
To prevent this natural movement, a retention phase is essential. These orthodontic devices are worn as part of this phase to maintain the results achieved during orthodontic treatment.
They come in two main forms: removable orthodontic devices or fixed wires bonded behind your front teeth.
1. Removable Retainers
Removable retainers can be taken out when needed, and most people remove them during meals and before brushing their teeth.
If you’ve been prescribed to wear them full-time, the routine is fairly simple: remove during mealtimes, rinse or clean as advised, and pop them back in before bed.
They’re convenient and relatively easy to manage, but they do require discipline. And since they aren’t fixed in place, they’re more prone to being lost, accidentally thrown out with lunch napkins, or damaged when not stored properly.
There are two common types of removable retainers: clear plastic and Hawley (wire) retainers.
Pros
- Designed for quick and simple removal during meals and oral hygiene routines
- More flexibility with oral hygiene routines
Cons
- Can be lost or damaged if not stored in a case
- May collect bacteria if not cleaned properly
Clear Plastic Retainers
Clear plastic retainers, such as Zendura, are custom-moulded to fit your teeth and maintain their alignment after braces. They are nearly invisible when worn, making them a discreet option for those who prefer something less noticeable.
Pros
- Discreet and almost invisible
- Thinner and more comfortable than Hawley retainers
- Less likely to affect speech
Cons
- Prevent natural contact between the upper and lower teeth
- Can’t be adjusted or repaired — must be replaced if cracked
- May warp if exposed to heat
- Can stain or discolour over time
Hawley Retainers
Also known as wire retainers, these retainers are made from a combination of acrylic and metal. The acrylic plate rests along the roof of your mouth or behind your lower teeth, while a visible wire stretches across the front teeth to keep them aligned.
Pros
- Allows upper and lower teeth to meet naturally
- Can be adjusted or repaired if needed
- Typically more durable than clear plastic retainers
Cons
- More visible when worn
- May affect speech more noticeably
- Can cause irritation to lips or cheeks, especially early on
2. Permanent Retainers
Permanent retainers — also known as fixed, bonded, or lingual retainers — are made from a thin metal wire. This wire is shaped to fit snugly along the back of the front teeth and is bonded in place using dental adhesive. Because they stay in your mouth at all times, they’re often used in cases where the risk of relapse is high or when patients may have trouble consistently wearing a removable retainer.
These retainers are designed to be worn indefinitely unless they contribute to ongoing plaque buildup or oral hygiene issues that cannot be managed through regular care.
Pros
- Hidden from view since they sit behind the teeth
- No impact on speech
- Can’t be lost or accidentally thrown away
Cons
- More effort needed to keep clean
- Plaque and tartar may collect around the wire
- Some people may experience tongue irritation from the metal
Why Are Retainers Required?
As mentioned, after your braces come off, your teeth aren’t locked in place forever. Even everyday habits like chewing or grinding can slowly shift them out of alignment. That’s where retainers come in — they help hold your teeth in position and protect the results of your orthodontic treatment.
Your orthodontist will recommend a retainer type and wear schedule based on your specific treatment plan. In most cases, retainers are worn full-time at first, then transitioned to night-time use long-term — for as long as you want to keep your teeth straight.
What Happens When I Start Wearing My Retainers?
Once you begin wearing your retainers, your dentist will arrange follow-up visits to ensure they still fit properly and do their job.
If your retainers become loose, damaged, or uncomfortable, they may need to be adjusted, repaired, or replaced.
If you lose them altogether, see your dentist as soon as possible — waiting too long can undo months or even years of progress.
How to Clean Removable and Permanent Retainers
Your retainers spend hours pressed up against your teeth and gums, making them a prime spot for plaque and bacteria to build up. Given this, if they are not cleaned properly, it might bring about dental issues like bad breath and even increase your risk of tooth decay or infections.
As such, regular cleaning is essential to keep both your retainers and your oral health in good shape.
How to Clean Removable Retainers
Clear plastic and Hawley retainers are both removable, which makes cleaning them more straightforward. It’s best to clean them while they’re still moist to stop food debris or plaque from hardening.
Here are a few simple ways to keep them clean:
- Method 1:Â After eating, rinse your retainer with lukewarm water and gently brush it using a soft toothbrush to remove any residue.
- Method 2:Â Mix a small amount of mild dish soap with lukewarm water, then use a separate toothbrush (not your usual one) to clean your retainer thoroughly.
- Method 3:Â For areas that are hard to reach, use a cotton swab to clean the inside edges and corners of your retainer.
- Method 4: Dissolve a retainer cleaning tablet in a cup of lukewarm water and soak your retainer as directed. Not all retainers are suitable for this method, so it’s best to check with your dentist first.
How to Clean Permanent Retainers
Because permanent retainers are a fixture in your mouth, meticulous daily brushing and flossing are now an indispensable ritual to ward off plaque accumulation along the wire.
When brushing, use a soft-bristled toothbrush and focus on the back of your teeth. Clean in small, circular motions around each tooth and along the wire.
To floss, follow these steps:
- Step 1:Â Â Use a floss threader to guide the floss beneath the retainer wire and between two teeth.
- Step 2:Â Gently move the floss up toward the gums, reaching just under the gum line if possible.
- Step 3:Â Curve the floss in a C-shape to clean both sides of each tooth.
- Step 4:Â Move along the retainer, repeating the process for each space.
- Alternative: If flossing proves tricky, an interdental brush can be used to clean between the teeth and beneath the wire. Just make sure you’re using the correct size to avoid damaging the gums — your dentist can advise on this.
Do’s and Don’ts of Cleaning Removable Retainers
Taking proper care of your removable retainers helps keep them clean, effective, and bacteria-free. Here’s what to keep in mind.
Do’s
1. Keep Your Retainers in Liquid When Not in Use
Always soak your retainers in water or a cleaning solution when you’re not wearing them. This helps prevent dry buildup, tartar, and biofilm from forming on the surface.
2. Clean Your Retainer Case Regularly
Don’t forget the container. Use warm water and a gentle dishwashing soap to scrub every surface of your retainer case. Rinse well and let it air dry before the next use.
Don’ts
There are also a few things that should never come near your retainers — even if they seem harmless at first glance.
1. Avoid Hot Temperatures When Cleaning
Heat can warp plastic retainers. Skip the boiling water, microwaves, dishwashers, and dryers — all of which can distort the shape permanently.
2. Skip the Mouthwash and Alcohol-Based Cleaners
Mouthwash and alcohol can dry out the material and lead to cracks or brittleness, making your retainers easier to break.
3. Don’t Use Toothpaste to Scrub
Toothpaste may feel harmless, but its abrasiveness can scratch the surface of your retainer, leading to tiny pits where bacteria can thrive.
4. Don’t Use Hydrogen Peroxide
Although it’s a disinfectant, hydrogen peroxide can wipe out helpful bacteria along with the harmful ones — disrupting your oral microbiome.
5. Don’t Eat or Drink with Your Retainers On
Remove your retainers before meals or drinks like coffee, tea, red wine, or curry. These can cause stubborn stains that are hard to reverse.
6. Never Clean with Bleach
Bleach is too harsh and can damage the material of the retainer. Worse, if even a small amount remains on the retainer, it can be harmful when placed back in your mouth.
When to Clean Your Retainers
This might not come as a surprise, but daily cleaning is essential to keep your retainers free from plaque, bacteria, and food debris. While a simple rinse or gentle brush should be done every day, a more thorough clean is recommended once a week.
You should also clean your retainers immediately if you notice:
- A bad smell or odd taste
- A slimy film on the surface
- A cloudy or dull appearance
- White spots or residue buildup
- Visible cracks or damage
If you’re experiencing new dental issues like sensitivity or tooth decay, it’s a good idea to have your retainer and overall oral health checked by your dentist. A poor fit or buildup can make existing problems worse.
When to Change Your Retainers
And, of course, retainers don’t last forever — and knowing when to replace them can prevent setbacks in your orthodontic progress.
1. It No Longer Fits
If your retainer feels tight or doesn’t sit properly anymore, it may have warped from heat exposure, or your teeth may have shifted due to inconsistent wear. Wearing an ill-fitting retainer can do more harm than good. If you notice this, book a visit with your dentist to get it assessed or replaced.
2. There’s a Buildup of Calcium
Mineral deposits can build up over time, especially if retainers aren’t cleaned thoroughly. If you’re unable to remove the chalky white residue with regular cleaning, it may be time to replace your retainer.
3. It Has Cracks
Cracks or fractures in your retainer can weaken its structure and reduce its effectiveness. A damaged retainer may no longer hold your teeth in place and could even cause irritation. Don’t wait too long — get it checked and replaced if needed.
