Krupp also stressed the importance of cleaning the bottom of the tongue also at a rate of 3 times a week with a tongue scraper “Tongue Scraper/Cleaner”, given that harmful bacteria often settle there.

And on how to use a tongue scraper, Krupp explained that the scraper is moved on the surface of the tongue at a rate of 5 to 7 times, starting from the back side towards the tip of the tongue, taking into account the exercise of light pressure while doing so to remove the accumulated layer of bacteria without feeling pain.
