Why is flossing as important as brushing? Explanations and techniques

Dental Floss: Why is it as important as brushing?


Brushing your teeth is a deeply ingrained habit in our daily routine, but did you know that dental floss plays an equally crucial role in maintaining a healthy mouth? According to the WHO, oral diseases affect nearly 3.5 billion people worldwide, and many of these problems could be prevented with regular flossing .

The crucial role of dental floss is to reach areas inaccessible to a toothbrush. This simple action is key to preventing gum recession and infections.


1. Dental Floss: An Ally Against Plaque and Cavities


Even when used correctly, a toothbrush only cleans 60% of the tooth surface. The remaining 40%, located between the teeth and under the gum line, are areas prone to the accumulation of plaque and bacteria. This is where dental floss comes in.

  • It removes food residue and plaque between teeth, where the brush cannot reach.

  • It reduces the risk of interdental cavities, which are often painful and expensive to treat.

  • It prevents gum diseases (gingivitis, periodontitis), which can lead to more serious problems such as tooth loss.


2. How to Use Dental Floss Properly?


Improper use of dental floss can cause bleeding or be ineffective. Here is the technique recommended by dentists:

  • Take 30 to 40 cm of thread and wrap it around your middle fingers, leaving 2 to 3 cm for passage between the teeth.

  • Gently slide the floss between each tooth, forming a "C" around the tooth to thoroughly clean the gum.

  • Repeat the up-and-down movement, without forcing it to avoid damaging the gums.

  • Use a clean section of floss for each interdental space.

Tip: If regular dental floss is difficult to handle, opt for water jets or interdental sticks, which are just as effective.


3. Dental Floss vs. Interdental Brushes: Which to Choose?


  • Dental floss : Ideal for close-set teeth and narrow spaces.

  • Interdental brushes : Perfect for people with implants, bridges, or wider spaces between teeth.

  • Water jet : Recommended for deep cleaning, especially for those wearing orthodontic appliances.


4. Mistakes to Avoid When Flossing


  • Use dental floss only before brushing: It is more effective to use it after brushing, to remove dislodged residue.

  • Forcing the thread through: This can injure the gums and cause bleeding.

  • Neglecting back teeth: Molars are often forgotten, even though they are very prone to cavities.


5. How often should I use dental floss?


Dentists recommend using dental floss at least once a day, ideally in the evening before bed. A study by the International Dental Federation shows that daily flossing reduces the risk of cavities and gum disease by 40%.


Conclusion: Dental floss, a simple step for a healthy mouth


Incorporating dental floss into your oral hygiene routine is an investment in your health. By combining brushing, flossing , and regular dental checkups, you maximize your chances of maintaining healthy teeth and gums throughout your life.
