Most people brush their teeth twice a day and feel confident they are doing enough. But brushing alone does not clean your entire mouth.
A toothbrush, even an electric toothbrush, simply cannot reach the tight spaces between teeth or fully clean along the gumline. These areas are where plaque and bacteria accumulate most easily. Over time, this build-up can lead to tooth decay, gum inflammation and eventually more serious periodontal problems.
Flossing is not an optional extra, it is an essential part of maintaining a healthy mouth.
When asking why is flossing important? the answer lies in the areas your toothbrush simply cannot reach.
Even with excellent brushing technique, studies show that up to one third of the tooth surface remains untouched without interdental cleaning. Dental plaque left between the teeth gradually hardens into tartar, irritates the gums and creates the perfect environment for harmful bacteria to thrive.
This can lead to:
Flossing removes plaque and food debris from the tight spaces between teeth, helping to prevent inflammation before it starts. By disrupting bacterial colonies daily, you reduce the risk of gum disease and protect the long-term stability of your teeth and implants.
Importantly, gum health is closely linked to overall health. Reducing the bacterial load in the mouth does not just support a healthy smile, it supports your wider wellbeing too.
Flossing should be done at least once a day, ideally in the evening once you have finished eating for the day. This is to help prevent bacteria sitting in your mouth overnight.
If you use traditional string dental floss:
Make sure you use a clean section of floss for each gap, as this prevents transferring bacteria.
A common question is whether you should floss before or after brushing. The simple answer is floss first, then brush.
Flossing before brushing removes plaque and food debris from between the teeth, allowing your toothbrush and toothpaste to reach more surfaces effectively. Once those tight spaces are cleared, fluoride from your toothpaste can better access the areas between the teeth, helping to strengthen enamel and reduce the risk of decay.
Research also suggests that flossing first may result in greater plaque removal overall compared to brushing first.
It is common for gums to bleed slightly if you are new to flossing or have not been cleaning between your teeth regularly. Plaque build-up causes inflammation (gingivitis), making the gums more sensitive and prone to bleeding.
With consistent daily flossing, this usually improves within a week as the inflammation reduces and the gums become healthier.
However, persistent bleeding may indicate:
If bleeding continues beyond one to two weeks, or is accompanied by swelling, discomfort or bad breath, it should be assessed by a dental professional.
Healthy gums should not bleed with gentle flossing. Consistent interdental cleaning is key to restoring and maintaining gum health.
Flossing plays a critical role in removing the physical biofilm that builds up between teeth, an area your toothbrush simply cannot reach. By disrupting this bacterial layer daily, you create the foundation for healthier gums and reduced inflammation.
When flossing is combined with fluoride toothpaste and an appropriate mouthwash, the result is a cleaner, more balanced oral environment where gum tissue can repair and inflammation can subside.
Flossing first also clears compacted debris and plaque from tight interdental spaces. This allows the active ingredients in toothpaste and mouthwash to penetrate more effectively into areas that were previously blocked, maximising their protective and therapeutic benefits.
Flossing is essential for removing the physical structure of plaque between teeth. However, effective oral care also involves supporting the biological environment that remains after biofilm has been disrupted. This is where blue®m adds significant value.
Flossing may occasionally cause mild irritation, particularly if the gums are already inflamed. blue®m’s oxygen-based formulations are designed to be gentle while actively supporting tissue recovery. Active oxygen and carefully selected supportive ingredients help calm irritated gums, reduce harmful bacteria, and promote natural regeneration.
This is especially beneficial for:
Flossing mechanically disrupts and removes plaque. blue®m helps optimise the oral environment that follows.
Used together, they create a more comprehensive approach to daily care:
The result is not only cleaner interdental spaces, but a mouth that remains fresher and healthier for longer. By combining mechanical plaque removal with oxygen-based support, you address both the cause of gum problems and the conditions that allow harmful bacteria to return.
Daily flossing prepares the foundation. blue®m helps protect and maintain it.
