We asked Dr. Jennifer Silver about interdental brushes. Here’s what she had to say.

What are Interdental Brushes?

Interdental brushes are small, cone-shaped brushes designed to clean the hard-to-reach regions between your teeth.

They typically have a small, spherical or cylindrical head made of fine bristles or filaments. You can put them into the interdental gaps and pushed back and forth to remove plaque and food particles.

Are Interdental Brushes as Effective as Floss?

Interdental brushes can be as effective as floss for removing plaque and debris between teeth, particularly in bigger spaces.

Some studies indicate that they may be even more beneficial than floss in some circumstances.

How Do You Use Interdental Brushes?

To use an interdental brush, choose a size that corresponds to the space between your teeth, then place the brush between your teeth and slide it back and forth to eliminate debris.

It is important to avoid forcing the toothbrush into the gap, as this might cause damage to the gums. Rinse the brush with water after use and replace it often.

Who Should Use Interdental Brushes?

Anyone can benefit from utilising interdental brushes, but people with:

  • braces
  • bridges
  • implants
  • diastema

may find them particularly useful.

What are the Best Interdental Brushes?

The best interdental brushes for you will depend on the size and spacing of your teeth and the location of the interdental gaps you want to clean.

Popular interdental brush brands include:

GUM Proxabrush Interdental Brushes
Oral B Precision Clean Interdental Brushes

It’s crucial to find a brush that fits properly between your teeth and doesn’t create pain or discomfort when used.

Are There Any Side Effects of Interdental Brushes?

Side effects of interdental brushes are generally modest. They may include bleeding or discomfort of the gums, especially if the brush is used too aggressively or in a region that is too narrow.

However, these side effects typically resolve on their own and should not cause concern.

Do Interdental Brushes Cost More Than Floss?

The price of interdental brushes might vary based on the brand and quantity included in a bundle.

In general, they may be slightly more expensive than dental floss, although the price difference is typically not substantial.
