Correct Use of Dental Floss

Dental floss is one of the most important tools for daily oral hygiene — and at the same time one of the most misunderstood. Although many people believe brushing is enough, the truth is that no toothbrush can effectively clean the spaces between the teeth. This is exactly where dental floss works, removing plaque and food debris from areas that would otherwise lead to cavities and gum disease.

In this article, you will learn when, how, and why you should use dental floss daily.

Why is dental floss essential?

• Cleans the interdental spaces where the toothbrush cannot reach.

• Prevents gingivitis by removing plaque along the gumline.

• Reduces the risk of cavities, which often develop between teeth.

• Significantly improves breath by reducing food debris retention.

• Enhances overall oral hygiene, making brushing more effective.

How often should we floss?

Dentists agree:

👉 Once a day
Ideally at night, before brushing.

This removes food particles and plaque that accumulated throughout the day, allowing the toothpaste to work more effectively.

How to use dental floss properly – Step by Step

1. Use 40–45 cm of floss
Wrap the ends around your middle fingers and leave a 2–3 cm working section between them.

2. Guide the floss gently between the teeth
Make small horizontal movements to pass it through without injuring the gums.

3. “Hug” the tooth in a C-shape
Curve the floss around one side of the tooth to clean the entire surface up to the gumline.

4. Move gently up and down
Avoid pressing forcefully. Movements should be small and controlled.

5. Repeat on the other side of the same space
Each gap has two tooth surfaces, both of which need cleaning.

6. Use a clean section of floss for each tooth
Shift the floss on your fingers so you always use a fresh part.

Does floss make teeth “loosen” or move apart?

No. Dental floss does not change the position of the teeth.
If it feels like it’s “getting stuck,” it may indicate:

• plaque or tartar,

• early cavity,

• a faulty filling,

• a tight interdental space.

In these cases, flossing is even more important and should be evaluated by a dentist.

Which type of floss should I choose?

• Waxed floss: easier to use; slides more smoothly.

• Unwaxed floss: slightly better cleaning but may catch more easily.

• Floss picks: good for beginners or children, but less effective than classic floss.

• Superfloss: ideal for bridges, braces, and wider spaces.

Your dentist can recommend the best option for your needs.

Common mistakes to avoid

• Snapping the floss down onto the gums

• Using too short a piece of floss

• Skipping surfaces

• Using floss before interdental brushes (if recommended)

• Not flossing daily

Conclusion

Dental floss is one of the simplest yet most crucial steps for a healthy mouth. With just 2–3 minutes a day, you can prevent gingivitis, bad breath, and cavities, keeping your teeth and gums strong for many years.
