Systema dental floss

This is Systema dental floss, said to be the pinnacle of dental floss.

It is a sponge floss that expands when it comes into contact with water.

So it seems like it cleans thoroughly without missing any spaces between the teeth.

No matter how well you brush, the spaces between your teeth cannot be cleaned.

They say you really need to floss.

I'm surprised too when I brush and floss diligently.... haha

Anyway, Systema dental floss is effective, so I use it often.

I try to use it at least three times a week.
