The Ins and Outs of Interdental Brushes

We have previously provided advice on how best to keep your teeth clean using a toothbrush but it’s important you also clean the hard to see or reach parts of your teeth as well. Cleaning between your teeth and on your gumline is essential to ensuring you have removed all plaque and food particles. To clean these areas, we use flossing or interdental brushing as a regular toothbrush unfortunately cannot reach them.

Interdental brushes have small bristled heads designed to get between your teeth. They come in different widths to suit the sizes of the gaps, you can buy them from your dental practice, pharmacies and in the supermarket. If you are unable to get out, then you can always use the CTS website to buy supplies directly.

Another option is dental floss and is recommended for use where the gaps in your teeth maybe too hard to clean with an interdental brush. Individuals may also have a personal preference on using one or the other or a mixture of the two. Research does show that interdental brushes provide better plaque removal than floss.

From the age of 12, as well as brushing twice daily, we recommend that you should clean between your teeth at least once a day, ensuring you keep a regular pattern so that you don’t miss any areas. Sometimes, looking in a mirror can help to ensure that you reach the gaps in every tooth. For children under the age of 12, they may need help with flossing safely and this can start as soon as they will let you do this.

How to use interdental brushes

Make sure you use a brush appropriate to the size of the space between your teeth as you may need more than one interdental brush. Your dentist/hygienist can help you to find the right size. They are coloured to represent the different widths. They also come with short or long handles to make it easier to reach the teeth further back.

Holding the interdental brush between your thumb and finger, gently place the brush through the gap between your teeth. Do not force the brush head through the gap, if the brush bends then it is too big and you’ll need to use a smaller brush head.

Work your way around the gaps between each tooth in an orderly way so that you don’t miss any of the spaces. When you first start using interdental brushes, your gums may bleed, they may also be tender as you start to remove any plaque build-up. Bleeding is a sign that the gums are not healthy, but this is completely normal if you have not cleaned in between your teeth in this way before. If you can carry on using the brushes, bleeding should reduce as your gums become healthier.

If your gums are still bleeding after a few days, seek advice from your dentist as you may be using the interdental brushes incorrectly.

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.
