Key takeaways
To floss with a permanent retainer, you need a tool that can go under the retainer wire.
Use a floss threader
Prepare the floss: Cut about 18 inches of dental floss.
Thread the floss: Loop the floss through the loop of the floss threader.
Guide the floss: Gently push the stiff, looped end of the threader under the retainer wire.
Floss between teeth: Once the floss is behind the wire, remove the threader and grip the ends of the floss.
Clean each tooth: Curve the floss into a "C" shape around each tooth and slide it gently up and down, going beneath the gumline.
Repeat: Move to the next tooth and repeat the process until all teeth connected to the retainer are cleaned.
Use super floss
Super floss has a built-in stiff end that functions like a threader, saving a step in the process.
Simply guide the stiff end under the wire and then proceed with the normal flossing technique around each tooth.
Important tips
Be patient: It may take time to get the hang of flossing with a permanent retainer, so don't get discouraged.
Brush regularly: Brush your teeth twice a day using a soft-bristled toothbrush and fluoride toothpaste, paying special attention around the retainer.
See your orthodontist: If you are having difficulty, ask your dentist or orthodontist for guidance on how to best clean around your specific retainer.
Use a water flosser
A water flosser is another effective tool that can make cleaning around a permanent retainer simpler and quicker.
It uses a stream of water to remove plaque and food particles from between your teeth and under the wire.

Why flossing is harder with a permanent retainer
Before getting into the how, let's dig into the why. Why do permanent retainers make it hard to floss?
Imagine how to use floss. You take the floss string and slide it between your teeth. But, since you have a permanent retainer, the wire blocks direct access. It means that there will be areas that the floss cannot reach. Here, food particles and plaque will stay trapped.
With continued buildup, you'll be at risk of:
-
Gum inflammation and bleeding.
-
Plaque and tartar buildup.
-
Cavities in hard-to-reach areas.
If you have the right tools, though, you can easily work around the wire to clean thoroughly.
Flossing with a permanent retainer
The main idea is to somehow reach all the areas that permanent retainers have rendered inaccessible. There are tools in the market that can help you clean those parts. For example, floss threaders, super floss, and water flossers. Here's more on these tools.
Floss threader
This tool works like a needle. It guides the floss wire to the nooks and corners that are otherwise inaccessible. Here's how to use a floss threader:
-
Take your regular floss thread and pass it through the loop.
-
Use the stiff end of the threader to go under the retainer wire.
-
Then wrap your tooth with the wire in a “C” shape.
-
Now, slide up and down the tooth along the gum line.
-
Repeat for all teeth.
It is very effective for deep cleaning. But, it's a bit time-consuming. And if you aren't cool with that, you can try the next one.
Super floss
A super floss is a pre-cut string. It has a stiff end, followed by a spongy part, and then the regular floss. It is often considered the best way to floss with braces, designed specifically for this purpose. Here's how it works:
-
Slide the stiff end under the wire.
-
Then use the spongy sections to clean around the wire and the gumline.
-
Use the floss to clean between the teeth.
Super floss is way quicker than a threader. But each pre-cut piece is single-use only.
Water flosser
This flossing tool doesn't use a string at all. Rather, it relies on pressurized water. A stream of this water cleans the hard-to-reach areas. To use it:
-
Just point the nozzle at the gumline or between the teeth.
-
Glide it along each tooth, though pause around the retainer wire for thorough cleaning.
-
Finally, rinse your mouth with a mouthwash or water to clear it all out.
Water flossing is quick, convenient, and useful for people with limited dexterity. However, it isn't too effective against stubborn plaque.
Important tips for flossing with a permanent retainer
You've got the tools. You know how to use them. Now, have a look at these important tips to make it easier and safer.
-
Be gentle. Tugging too hard may damage gums or loosen the wire.
-
Use a mirror while learning the technique.
-
Ask your dentist for a hands-on demo if you're struggling.
-
Brush + rinse afterward to complete your cleaning routine.
Another important tip: never neglect it. Flossing is essential for your oral health if you're wearing a retainer. Done right, it'll result in a radiant smile.
Are interdental brushes better than floss?
People wonder if interdental brushes can replace floss. These small, cone-shaped brushes are designed to fit between teeth and gently scrub away plaque. Let's explore the pros and cons, and compare it with floss.
Pros of interdental brushes
Here are some benefits:
-
They are easy to maneuver, especially around the retainer wire.
-
They are effective for removing food particles stuck near the gums.
-
They can be reused for a short period (rinse after each use).
Cons of interdental brushes
These are the disadvantages:
-
They may not reach as deeply under the gumline as floss
-
They are less effective for cleaning tight spaces between teeth
-
Their bristles wear out quickly and need replacing
So, which is better?
For people with permanent retainers, interdental brushes can be a good supplement. But they are not a substitute for floss. The best approach is a combination. Use floss (threader, super floss, or water flosser) for under the wire and interdental brushes for quick touch-ups between meals.
With that said, your teeth and gums are not the only things to be focused on here. Your permanent retainer needs cleaning, too.
How to clean a permanent retainer
Keeping a permanent retainer clean is just as important as learning how to floss with it. Since the wire can trap food and plaque, a little extra care goes a long way.
Follow these steps to clean your permanent retainer:
-
Brush thoroughly: Angle your toothbrush to clean around the wire and along the gumline.
-
Use flossing tools: A floss threader, super floss, or water flosser helps remove debris under the wire.
-
Add interdental brushes: These can reach tight spaces around the wire that brushing might miss.
-
Rinse daily: Mouthwash or a water rinse helps flush away bacteria.
-
Schedule professional cleanings: Your dentist or hygienist can remove stubborn tartar that builds up around the retainer.
Just like you keep your aligners clean, or braces for that matter, a retainer needs to be maintained. If you do so, you'll face fewer dental issues and a healthier smile.
The easier alternative: Clear removable retainers
Permanent retainers work brilliantly. But, they come with a hassle. There's something in your mouth all the time. It makes cleaning difficult. You never feel really free. So, is there an alternative?
Well, clear removable aligners work equally well. And you don't have to wear them all the time. You can just remove them to eat or clean. Here are some more advantages:
-
No special flossing tools needed
-
Faster, more hygienic oral care
-
Greater flexibility and comfort

Flossing smarter with a permanent retainer
It is essential to floss teeth if you have permanent retainers. That keeps your smile clean and healthy. To do that, you can use tools like floss threaders, super floss, and water flossers. However, you'll require patience and consistency to do it right.
That being said, you can always choose the easier path of clear removable retainers. Once your braces or aligners treatment is done, removable retainers simplify daily care while preventing relapse.
