The process of removing debris, bacteria, and dead cells from the surface of the tongue utilizing methods that do not involve synthetic chemicals or artificial devices is a practice aimed at improving oral hygiene. An example includes using a tongue scraper made of stainless steel or copper rather than a plastic one, coupled with rinsing using a salt water solution instead of a commercial mouthwash.
This type of oral care offers several potential benefits, including reducing bad breath (halitosis), improving taste perception, and decreasing the overall bacterial load in the mouth. Historically, cultures around the world have employed various techniques and implements, like specialized sticks or herbs, to maintain tongue cleanliness, recognizing its importance for overall health and well-being.
