What is an Interdental Brush? And Do They Actually Work?
An interdental brush is a very small, thin brush, which is specifically made to brush the areas between your teeth, which cannot be easily brushed with a regular toothbrush filament. Imagine it is a small bottle brush in the tight crevices between your molars and incisors.
The question is, then, do interdental brushes work? The facts are overwhelming. In a meta-analysis study, published in the International Journal of Dental Hygiene in 2024, interdental brushes were found to be far more effective than the floss in the removal of plaque and gingivitis bleeding when used correctly. Most periodontists prefer the use of them due to the superior contact of the surface offered by their bristles over the slicing action of string floss.
The Unmatched Benefits: Why Your Dentist is Always Recommending Them
Moving beyond “they clean between teeth,” let’s explore the tangible benefits that make them a non-negotiable part of a modern oral hygiene routine.
- Better Removal of Plaque: The bristles clean the concave root areas and small areas of contact where plaque biofilm grows.
- Preventing Gum Disease: When you disrupt plaque on a daily basis, you prevent the inflammation which causes gingivitis and eventually periodontitis.
- Ideal on Dental Work: Ideal on dental work, they are essential in cleaning around implants, bridges, orthodontic brackets and permanent retainers. Cleaning the implants with an interdental brush is very essential to avoiding peri-implantitis which is a major cause of implant failure.
- Ease of Use: The interdental brush with long handle is much easier and more effective to use than floss on a string when one has a problem with dexterity or arthritis and a very high gag reflex.
The Ultimate Sizing Guide: Finding Your Perfect Fit
This is the most important step. When a key is used on a different lock, it will not fit, or it will not be of any use. The aim is to be able to use the maximum size that will comfortably fit between your teeth without pushing it.
A color-coded coding and numbered size scale (e.g. interdental brushes size 0 extremely tight spaces, interdental brush wide space areas interdental brush size 4 or more) are used by most brands.
- Pink/Size 0 (0.4mm): For extremely tight contacts, often found between lower front teeth.
- Orange/Size 1 (0.45mm): For tight spaces between anterior teeth.
- Green/Size 2 (0.5mm): A common size for mixed dentition.
- Purple/Size 3 (0.6mm): For average spaces between premolars.
- Yellow/Size 4 (0.7mm): For wider spaces, often around molars or in areas of past gum recession.
- Red/Size 5 (0.8mm+) For the widest gaps and under bridges.
Pro Tip from a Hygienist: You will likely need 2-3 different sizes for your entire mouth. Don’t buy a single pack. Invest in a multi-size starter kit to “audition” what fits best between your molars, premolars, and front teeth. The brush should have a slight resistance when inserted, but you should not have to bite down to force it through.
