Choosing your appropriate interdental brushes

There are several factors to consider when choosing an interdental brush which may affect its efficacy.

The size factor

This is the most important factor affecting the result of removing plaque between teeth. Too small, and the brush may not clean effectively. Too large, and you risk damaging your teeth or gums in the process. Dental professionals will measure the spaces between your teeth and advise you of the interdental brush size(s) you should use to fit snugly in the interdental spaces. Therefore, you may have a number of interdental brushes because of different sized interdental spaces.

If you want to know what size interdental brush to use without visiting a dentist, try purchasing a multipack with a variety of different sizes. Dental experts recommend that you should have 2 – 3 different sized interdental brushes for optimal two dental arches cleaning result. Additionally, you can use large sized brush to clean braces and wires if you are in orthodontic treatment.

The geometry factor

Waist-shaped interdental brush heads are found to remove significantlymore biofilm than straight ones. And straight interdental brushes may be more effective than angled interdental brushes with a long handle. A triangular or conical form of interdental brushes may also provide better adaptation to the interdental spaces.

The material factor

Metal wire core

Metal wire in the middle of interdental brushes can be uncomfortable for people with sensitive root surfaces. Rubber interdental brushes/picks are a more recent development and can be a viable alternative to conventional interdental brushes with the same effectiveness.
