How to Floss

Do you know how to floss properly? Our simple guide includes a video, step-by-step instructions, and answers to some of your most

Did you know that flossing is just as important as brushing your teeth?

This is because brushing alone only removes about 50% of the plaque in your mouth, whereas flossing as well can remove up to 70%.

Floss also reaches parts of the mouth that a toothbrush cannot, and where plaque can easily build up, like between the teeth and under the gumline.

Removing food residue and plaque from these areas is particularly important if you have an orthodontic appliance, bridge, or implants.

Flossing is easier than you think! Watch the video or follow the instructions below to find out how to floss properly.

What is the best way to FLOSS?

How to hold floss

First, wash your hands, then take around 15-20 cm of floss and wrap the ends around the middle finger of each hand. Using the thumb and index finger of each hand, grasp a segment of approximately 2.5 to 5cm and insert it, with the help of the thumbs, between the upper teeth.

How to floss

Keep a segment of the floss (around 2.5 to 5 cm) tight between your fingers and use your index fingers to insert it between the contact surfaces of two lower teeth.

Flossing in zigzag pattern

Gently move the floss between the teeth in a zigzag pattern, passing over the entire tooth. Make sure the floss doesn’t snap, as this can damage your gums.

How to floss

Using an upward and downward motion, gently slide the floss against the tooth surface and under the gumline. Floss each tooth with a clean section of floss.

Which is the right floss for me?

Many different dental flosses are available, so first you will need to find one that is adapted to your specific needs and feels comfortable.

Who should floss?

Everyone! Flossing is important, no matter what your age or state of health – children included. However, it is especially useful if:

  • You have particularly tight spaces between your teeth
  • You have individual implants
  • You have dental prostheses on natural teeth or implants
  • You wear an orthodontic appliance (we offer a special solution for orthodontic patients)

Do I need to floss between all my teeth?

Yes. Although it’s not easy to reach the back teeth, plaque can build up just as easily there – so make sure you floss between all your teeth. When should I floss? We recommend flossing at least once a day, for example in the evening after brushing your teeth.


Help, I keep forgetting to floss!

It's not always easy to remember to floss, but we all need to make it part of our daily routine. Here are our top tips to help you get started:

  • Always keep your floss close at hand, including when you’re traveling. Put it in your car, your bag, inside your diary, in the shower, or anywhere else where you won’t be able to miss it. Don’t leave it hidden away in the bathroom cabinet where you might forget about it!
  • Our studies have shown that if you floss for 21 days, then don’t floss on the 22nd day, you will instantly notice a difference. Then start flossing again on the 23rd day and enjoy that instantly cleaner feeling.
  • Teach children how to floss from a young age, so that it becomes a natural part of their oral care routine.
  • Choose easy-to-use floss that doesn’t shred easily. GUM® flosses are shred resistant and great for cleaning between teeth.
  • And if you keep forgetting to floss, try one of our other GUM solutions to clean between your teeth, such as GUM Interdental brushes and SoftPicks®
