interdental brush

It is a slide interdental brush.

When you press the button, the interdental brush comes out and becomes available for use.

After use, you can put it back inside to protect the toothbrush head from other things.

Since it is an SSS size, the bristles are on the thinner side, so it is easy to insert between the toothbrush teeth.

I was told not to use interdental brushes as much as possible.

It's like picking your teeth with a telephone pole.

This one is on the thinner side, so I keep using it.
