What Happens When You Don’t Floss? It’s More Than Just a Missed Step

What Happens When You Don’t Floss? It’s More Than Just a Missed Step

Posted by IDC Team | 10th March 2025 | Team News

We’ve all been there. After a long day, you brush your teeth, but you skip the flossing—just this once, right? Maybe you think, “It’s not that big of a deal,” or “I can get by without it.” But what if we told you that not flossing is more than just a missed step in your routine? Flossing is essential to maintaining your oral health and skipping it regularly can have serious consequences for your teeth, gums, and overall well-being.

While brushing your teeth removes plaque from the surfaces, flossing is the only way to get into those tight spaces between your teeth where your toothbrush can’t reach. The sad truth is that skipping this step can lead to several dental issues that you might not even be aware of. So, let’s explore what happens when you don’t floss and why this simple habit is one you can’t afford to overlook.

What Happens When You Don’t Floss?

At first glance, missing a day of flossing may not seem like a major issue, but the consequences of skipping this essential step can build up over time. Let’s break down what happens when you neglect to floss, and the risks involved:

  1. Plaque Builds Up Between Your Teeth

Plaque is a sticky, colourless film of bacteria that forms on your teeth after you eat. When you brush your teeth, you remove a significant amount of plaque from the surface of your teeth. However, there are still areas that your toothbrush can’t reach—the tight spaces between your teeth and under your gumline. This is where flossing comes in.

When you don’t floss, the plaque that remains in these hard-to-reach places can lead to several issues, including:

  • Tooth Decay: Plaque that remains on the teeth for too long produces acid, which can eat away at tooth enamel. This leads to cavities, the most common dental problem. The more plaque you leave between your teeth, the higher your risk for decay.
  • Gum Disease: Plaque that’s not removed can harden into calculus, which is much more difficult to remove. Over time, this can irritate your gums, leading to gingivitis (early-stage gum disease). Gingivitis is characterised by red, swollen, and bleeding gums. If left untreated, it can progress to more severe forms of gum disease, such as periodontitis, which can lead to tooth loss.
  1. Bad Breath (Halitosis)

We’ve all experienced it: bad breath, or halitosis. While it’s often associated with certain foods or drinks (garlic, onions, or coffee, for example), chronic bad breath is often a sign that you’re not maintaining proper oral hygiene.

The bacteria that thrive in plaque can produce unpleasant smells. When food particles and plaque get trapped between your teeth, the bacteria break them down, releasing sulphur compounds that contribute to bad breath. If you don’t floss, these particles stay stuck in your mouth, creating the perfect environment for persistent bad breath.

In fact, bad breath is often one of the earliest signs that your dental hygiene routine isn’t cutting it. If you consistently struggle with bad breath despite brushing, it may be a sign that you need to start flossing regularly to remove trapped food particles and bacteria.

  1. Increased Risk of Gum Disease

Gum disease is often referred to as the “silent disease” because it progresses slowly and may not cause noticeable pain or discomfort at first. However, untreated gum disease can lead to severe consequences, including tooth loss.

What happens without flossing?

Flossing is essential to preventing gum disease. When plaque and calculus build up between your teeth and below the gumline, they can irritate the gums, causing inflammation and infection. This can lead to gingivitis, the earliest stage of gum disease. Symptoms include redness, swelling, and bleeding when you brush or floss. If gingivitis is left untreated, it can advance to periodontitis, a more serious form of gum disease that can cause tooth mobility, receding gums, and even tooth loss.

Flossing regularly helps remove plaque from the spaces between your teeth and along the gumline, preventing it from hardening into calculus and reducing the risk of gum disease. Without flossing, you’re more likely to develop inflammation and infection that can take a significant toll on your oral health.

  1. Tooth Sensitivity and Discomfort

Ever noticed that your teeth feel more sensitive to hot or cold foods when you’ve been slacking on your flossing routine? While tooth sensitivity can be caused by a variety of factors, skipping flossing can contribute to the discomfort.

What happens without flossing?

When plaque builds up between your teeth and under your gums, it can lead to gum recession, where the gum tissue pulls away from the teeth. This exposes the sensitive root surfaces, which can lead to increased sensitivity to temperature changes or pressure. If left untreated, gum recession can also lead to more serious issues like tooth decay or tooth loss.

Flossing helps to prevent plaque buildup and keeps your gums healthy, reducing your risk of gum recession and tooth sensitivity. By removing debris from between your teeth, you help protect your gums from irritation and inflammation that can result in discomfort.

  1. Higher Dental Costs in the Long Run

Neglecting your oral health now can lead to significant dental issues down the road. What starts as a simple decision to skip flossing can result in cavities, gum disease, and other oral health problems that require costly treatments.

When you don’t floss, the plaque and calculus buildup eventually lead to dental problems that may require professional intervention, such as:

  • Fillings to treat cavities
  • Root canals if tooth decay reaches the pulp of the tooth
  • Gum treatments for advanced gum disease
  • Tooth extraction if teeth become loose or severely infected

The cost of treating these issues can add up quickly. In contrast, regular flossing is an inexpensive habit that helps prevent these issues from developing in the first place. By taking a few minutes each day to floss, you can save yourself significant amounts of money on future dental procedures.

  1. Impact on Your Overall Health

Your oral health doesn’t exist in a vacuum—it affects your overall well-being. Studies have shown that poor oral hygiene and untreated gum disease are linked to several serious health conditions, including heart disease, diabetes, and respiratory issues.

What happens without flossing?

If you don’t floss, the bacteria from your mouth can enter your bloodstream, potentially causing inflammation in other parts of the body. Research has found links between gum disease and heart disease, as the bacteria from the mouth can contribute to plaque buildup in arteries. Additionally, gum disease can worsen blood sugar control in people with diabetes.

By flossing regularly, you reduce your risk of these health issues and help keep your mouth—and the rest of your body—healthy.

Final Thoughts

Skipping flossing is more than just a missed step in your dental routine. It’s a habit that can lead to a host of dental problems, including plaque buildup, gum disease, tooth decay, and bad breath. Not flossing can also result in higher dental costs down the line, as well as potential health risks that extend beyond your mouth.

Flossing is a simple, effective way to protect your teeth and gums, ensuring that you maintain a healthy, beautiful smile for years to come. So, the next time you’re tempted to skip this step, remember the potential consequences and take a few extra minutes to floss. Your teeth—and your overall health—will thank you.
