Tongue scraping is an ancient oral hygiene practice rooted in Ayurvedic tradition, typically performed with a U-shaped copper or stainless steel tool drawn gently across the surface of the tongue. Research suggests that regular tongue scraping can significantly reduce volatile sulfur compounds associated with bad breath and may decrease populations of bacteria such as Mutans streptococci and Lactobacilli linked to dental decay and plaque formation. Studies indicate it may also help improve taste perception by clearing the coating that accumulates on the tongue's surface, and some traditional practitioners connect the practice to supporting digestive wellness, though scientific evidence for that particular benefit remains limited. Generally considered safe and inexpensive, tongue scraping has drawn growing interest as a simple addition to daily oral care routines.
