Maintaining healthy teeth and gums requires more than just brushing twice a day. Cleaning between your teeth is essential to remove plaque and food particles that a toothbrush cannot reach. Traditionally, floss has been the go-to tool for this task. However, interdental brushes have gained popularity as an effective alternative. This guide explains how to use interdental brushes properly and why they often provide better results than floss.

What Are Interdental Brushes?
Interdental brushes are small, specially designed brushes that fit between teeth to clean the spaces where a regular toothbrush cannot reach. They consist of a thin wire handle with bristles arranged in a cylindrical or conical shape. These brushes come in various sizes to fit different gaps between teeth.
Unlike floss, which is a thin string, interdental brushes physically scrub the sides of teeth and gums, removing plaque and debris more effectively in many cases. They are especially useful for people with wider gaps between teeth, braces, bridges, or dental implants.
Why Cleaning Between Teeth Matters
Plaque buildup between teeth can lead to gum inflammation, cavities, and bad breath. Brushing alone removes plaque from the tooth surfaces but misses the tight spaces where food often gets trapped. If left uncleaned, plaque hardens into tartar, which requires professional removal.
Regular interdental cleaning reduces the risk of gum disease and tooth decay. It also helps maintain fresh breath and overall oral health. Dentists recommend cleaning between teeth daily as part of a complete oral hygiene routine.
How to Use Interdental Brushes Correctly
Using interdental brushes is simple but requires some care to avoid damaging gums or teeth. Follow these steps for effective cleaning:
Choose the right size
Select a brush size that fits snugly but comfortably between your teeth. If the brush is too small, it won’t clean effectively. If it’s too large, it may hurt your gums.
Hold the brush gently
Grip the handle firmly but avoid forcing the brush. Insert it gently between teeth at a slight angle.
Move the brush back and forth
Use a gentle back-and-forth motion to clean the sides of each tooth and the gum line. Avoid twisting or forcing the brush.
Clean all gaps
Work your way through all the spaces between your teeth, including behind your back molars.
Rinse and store properly
After use, rinse the brush under running water to remove debris. Let it air dry and replace it when the bristles wear out.
Why Interdental Brushes Are Often Better Than Floss
Many people find interdental brushes easier and more comfortable to use than floss. Here are some reasons why interdental brushes often outperform floss:
More effective plaque removal
The bristles of interdental brushes physically scrub plaque from tooth surfaces and gums, while floss mainly slides between teeth without scrubbing.
Better for wider gaps and dental work
Floss can be difficult to use around braces, bridges, or implants. Interdental brushes come in sizes that fit these spaces better.
Less risk of gum injury
Floss can sometimes cut or irritate gums if used improperly. Interdental brushes are gentler and easier to control.
Easier for people with limited dexterity
People with arthritis or limited hand movement often find interdental brushes simpler to handle than floss.
Encourages consistent use
Because interdental brushes are easier and more comfortable, people are more likely to use them regularly.
When Floss Might Still Be Needed
While interdental brushes are excellent for many, floss still has a role in oral care:
Very tight spaces
Some teeth have extremely narrow gaps where even the smallest interdental brush won’t fit. Floss can reach these tight spots.
Under the gumline
Floss can sometimes reach slightly below the gumline better than brushes, helping remove plaque in that area.
Preference and habit
Some people prefer floss or find it more familiar. The best tool is the one you use consistently and correctly.
Tips for Choosing and Maintaining Interdental Brushes
Consult your dentist
They can recommend the right brush size and type for your teeth.
Try different sizes
You may need more than one size to clean all gaps effectively.
Replace brushes regularly
Worn bristles lose effectiveness and can irritate gums.
Use daily
Make interdental cleaning part of your daily routine for best results.
Additional Benefits of Interdental Brushes
Improves gum health
Regular use reduces inflammation and bleeding gums.
Prevents bad breath
Removing trapped food and plaque helps keep breath fresh.
Supports overall health
Healthy gums reduce the risk of systemic issues linked to gum disease, such as heart problems.
Choosing the right tool for cleaning between your teeth can make a big difference in your oral health. Interdental brushes offer a practical, effective, and often more comfortable alternative to floss. By incorporating them into your daily routine, you can improve plaque removal, protect your gums, and enjoy a healthier smile.
