As a dentist, I always recommend some sort of interdental cleaning as well as your brushing routine.
And it’s not just me, the National Health Service also recommends regular flossing.
You might be wondering “why is flossing important”?
In this article, I will explain the benefits of flossing to keep your mouth clean. I will also tell you some surprising benefits of flossing that you might not have heard of.
Flossing is one type of interdental cleaning method – one way of cleaning between your teeth.
Other options include using a water flosser or interdental brushes. For the sake of this article, flossing refers to any of these types of interdental cleaning.
If you’re just getting started with flossing, be sure to head over to our how to floss hub page to find lots of useful guides and tips.
Flossing Keeps Your Mouth Clean
Did you know that toothbrushing alone removes only 60% of plaque from your teeth?
This means that a significant amount of bacteria-containing plaque is still left behind after toothbrushing. Most of this is between the teeth.
This plaque is the direct cause for both tooth decay and gum disease. Removing plaque build up is important to keep your mouth clean.
Summaries of the research by Marchesan et al, Ng and Lim, and a review by Worthington et al proves:
- Flossing stops your gums bleeding.
- Flossing prevents gum disease.
- Flossing slows down advanced gum disease.
- Flossing prevents tooth decay
They all found that using interdental cleaning removes more plaque than only using a brush. Generally interdental cleaning brushes are better at this job than floss.
One final advantage in keeping your mouth clean is that flossing prevents tartar build up. Without tartar build up, you are less likely to suffer from staining on your teeth.
Flossing Prevents Bad Breath
Bad breath, or halitosis, is caused by poor oral hygiene and untreated gum disease.
Flossing prevents bad breath by:
- Removing plaque and food debris which cause bad smells in the mouth.
- Removing the food for the bacteria which release compounds that cause bad breath.
- Managing the gum disease and dental decay that contribute bad breath.
The National Institute for Health and Excellence (NICE) actually recommends interdental cleaning as part of the oral hygiene measures to manage halitosis.
When you first start flossing you may even notice a bad smell that wasn’t there before. For more advice on this you can check out my article: what to do if your breath smells bad after flossing.
Flossing Helps You Keep Crowns And Bridges For Longer
Briggs et al found the most common cause of failure of crowns and bridges is dental decay.
Plaque is central to the decay process.
Flossing, and the alternatives, will remove the plaque from around the edges of crowns and bridges. Gold standard cleaning will help them last as long as possible.
Flossing Prevents Tooth Loss
Flossing is known to prevent tooth loss. Studies show that people who use interdental cleaning aids have more natural teeth than those who rely on brushing alone.
This comes down to removing plaque from the teeth and gums.
Failure to manage the plaque in your mouth can lead to dental decay and gum disease. As these advance, you will need treatments such as fillings for your decay or a scale and polish for gum disease.
Untreated dental decay and gum disease will result in a tooth extraction.
Six Benefits of flossing you may not have heard of
I have explained how flossing helps to keep your mouth clean. But did you know there are many other benefits of using floss to keep your gums healthy?
The links between oral health and your general health have been well documented. The National Health Service (NHS) and the European Federation of Periodontology (EFP) have lots of information about the links between diseases of the body and gum disease.
Flossing Protects Against Heart Disease
Keeping your gums healthy by including flossing can prevent the gum disease which leads to heart disease. Other forms of interdental cleaning are also beneficial.
The Oral Health Foundation (OHF) states that people with gum disease are almost twice as likely to have coronary artery (heart) disease than people without gum disease.
Inflamed gums allow bacteria to enter the bloodstream from the mouth. This bacteria directly affects blood vessels and even the valves of the heart. This can lead to heart attacks.
Bacteria from the mouth are also a known cause of endocarditis, an inflammation of the heart lining.
The European Federation of Periodontology and World Heart Foundation recommend flossing to help protect against heart diseases.
Flossing Helps Avoid A Stroke
Recent research found that having gum disease can double your risk of stroke.
Failing to floss and keep your gums healthy leads to gum disease.
At advanced stages, gum disease can affect blood flow. This can have a devastating effect, cutting off the supply of oxygen to the brain, resulting in a stroke.
Look after your gums by flossing and you can reduce this risk.
Flossing Prevents Pneumonia
Pneumonia is an inflammation of the lungs. It can be caused by a variety of factors. One of these factors is bacterial infection due to poor oral hygiene.
Poor oral hygiene over extended periods of time will result in gum disease.
The OHF says “People with gum disease have more bacteria in their mouths and may therefore be more likely to get chest infections.”
The American Thoracic Society warns that bacteria in the mouth can be inhaled into the lungs. Although healthy bodies can normally defend themselves against this, disease affected lungs can be affected in a bad way by this.
Ensure you clean your teeth well twice a day, and floss daily to help prevent lung diseases.
Flossing Controls Diabetes (And Failing To Floss Causes Diabetes)
There is a very well known link between gum health and diabetes.
If you have diabetes, poor gum health is linked to difficulties controlling blood glucose levels. Diabetes UK recommends flossing to help manage your gum disease and diabetes.
If you don’t have diabetes, you should know that people with moderate or severe gum disease have a 69% higher risk of developing type 2 diabetes.
The European Federation of Periodontology advises daily interdental cleaning to manage gum disease. This can reduce the impact of gum disease on people with diabetes, and reduce the risk developing diabetes in the long term.
Flossing Promotes A Healthy Pregnancy
Hormonal changes during pregnancy are a given, but did you know that these changes affect the gums?
Even if a person normally has healthy gums, pregnancy can influence their body’s reaction to plaque. This altered response can cause gum disease.
Gum disease can affect a pregnant person’s confidence and oral health in the future.
Most gum disease will come and go as hormones change. This is pregnancy gingivitis.
But pregnant people with advanced gum disease are more likely to have a baby that is premature and has a low birth weight.
The British Society of Periodontology (BSP) encourages prevention over treatment. They say that during pregnancy it is especially important to keep flossing.
Flossing is an important part of your health care regime that will promote a healthy pregnancy, both for the pregnant person and for the unborn baby.
Not flossing could be linked with Alzheimer’s disease
Fusobacterium nucleatum (F. nucleatum) is a bacteria often found in people with advancing gum disease. This bacteria has been linked to various chronic conditions.
Some of the latest research has shown F. nucleatum “can generate systemic inflammation and even infiltrate nervous system tissues and exacerbate the signs and symptoms of Alzheimer’s disease”.
This is new reserach, and does not prove that the bacteria causes Alzheimer’s but it does suggest that periodontal disease caused by F. nucleatum and left untreated or poorly treated could exacerbate symptoms of Alzheimer’s disease. You can read more explanation of this via the website EurekAlert!
Previous research explained by The Dentist website also showed that discover that people who had suffered from gum disease for 10 years or more were up to 70 per cent more likely to then develop Alzheimer’s disease.
How do I start flossing?
So now that I’ve shared some surprising benefits of flossing, the next step is to start flossing.
You should be flossing, or using another type of interdental cleaner, once a day. Try to do this before you brush your teeth in the evening.
Clean between your teeth using floss (or otherwise) in addition to brushing twice a day with fluoride toothpaste.
It is best for you to go to your own dentist or hygienist. They will make you your own personalised plan that is unique for your mouth.
