Woman with braces cleans her teeth using an interdental brush

Invented in the 1980s as an alternative to flossing, interdental brushes have made a significant impact on oral hygiene. They are effective at removing plaque and tartar from hard-to-reach areas, such as between braces, bridges, and crowns. However, many people still have questions about their proper use. If you want to add an interdental brush to your oral hygiene routine, here’s everything you need to know about using them safely and effectively:

#1 Can you reuse interdental brushes?

We know reusing floss is a definite no-no, but are interdental brushes reusable? The quick answer is yes!

However, it does depend on the specific brand and brush quality. If the brush’s bristles are still intact and clean after use, you can rinse it thoroughly, let it dry, and use it again. 

It is generally recommended to replace an interdental brush after a few uses or if the bristles become worn or deformed, as this can reduce its effectiveness. 

Reusing a brush too often can also introduce bacteria to your gums, so replacing it regularly is ideal to maintain good oral hygiene.

#2 Can interdental brushes damage gums?

When used correctly, interdental brushes should not harm your gums. 

However, you do risk irritating or damaging gum tissue if you choose a brush size that’s too large or apply too much pressure. 

To avoid this, select a brush that fits comfortably between your teeth without forcing it, and always use gentle, controlled movements. If you're unsure, a dental professional can guide you on the right brush size and technique.

#3 When should you use an interdental brush?

The question of when to use interdental brushes is somewhat a matter of personal preference; however, it is generally recommended that they be used once per day - typically before bed at night.

Cleaning between teeth before bed removes any food particles or plaque accumulated during the day, promoting gum health overnight. 

For those with braces or dental work, using an interdental brush can be especially beneficial after each meal as it can reach difficult areas that standard toothbrushes might miss. 

#4 Interdental brush vs floss | Which is better?

Interdental brushes and floss each have their advantages. Floss effectively removes plaque between tightly spaced teeth, while interdental brushes are handy for people with wider gaps, braces, or implants. 

The bristles on interdental brushes work to clean the sides of teeth more thoroughly in larger spaces than floss. 

Many dentists recommend a combination of both for optimal oral health, depending on your specific dental needs.
