How to use interdental brushes

Step-by-step instructions

Make it a daily routine to brush between your teeth with an interdental brush. It will keep your mouth healthy and prevent gum inflammation and cavities. Interdental brushes can also be used for cleaning of implants and orthodontic appliances.

Make interdental brushes part of your daily routine

Did you know that a toothbrush can only reach 60% of the tooth surfaces? Dental plaque builds up between your teeth where a toothbrush does not reach. It is a good idea to use an interdental brush as part of your daily cleaning routine to prevent gum inflammation, cavities and bad breath.

An interdental brush is a small brush specially designed to clean between your teeth, where a regular toothbrush does not reach. Daily use of an interdental brush in addition to regular toothbrushing, is an easy and efficient way to keep your gums and teeth fresh and healthy. 

Choose the right size 

For best result, it is important to choose an interdental brush of the right size. Often, you need more than one brush size and your dental professional can help to select the correct brush size or sizes for you. If you for any reason don’t have access to a dental professional, try TePe interdental mix-pack to find a suitable size.


Use your interdental brush once a day, preferably in the evening and in front of the mirror. Move the brush gently back and forth a few times in each interdental space.

Don’t use regular toothpaste, since it contains abrasives. You can instead apply TePe Gingival Gel with chlorhexidine and fluoride, which is specially designed for use with an interdental brush.

How do I use the interdental brush?

  1. Choose the right size
  2. Insert gently
  3. Move the brush back and forth in each space
  4. Change size and curve the neck or wire when needed
  5. Change the brush when the filaments become worn

How to use interdental brushes between the front teeth

How to use interdental brushes between the back teeth

See different instructions for small and big interdental brush sizes. 

If you use a small interdental brush (pink, orange, red or blue) you may curve the soft neck slightly. 

By adding pressure with your finger to make it easier to reach between the back teeth.

If you use an interdental brush of a larger size, access between the back teeth may be improved if you slightly curve the wire. 

The interdental brush will last longer if you do not straighten or bend the brush at another angle.
