I'm using an interdental brush.

I leave it at the office or carry it around as a portable device.

That plastic case is good for carrying interdental brushes around.

After you're done using it, you can recycle it as a container for toothpicks or cotton swabs.

It is very useful.

Thick or hard interdental brushes can sometimes cause bleeding or pain.

This product is thin and soft, so it fits well between teeth.

It effectively removes food stuck between teeth.
