Tongue scraping physically removes bacteria, food debris, and dead cells from the tongue's surface, which can reduce the volatile sulfur compounds (VSCs) responsible for halitosis. From a healthspan perspective, this practice may help modulate the oral microbiome, potentially reducing the systemic inflammatory burden linked to poor oral hygiene, though this connection is speculative.
Verdict
A low-cost, safe hygiene habit; direct healthspan impact is unproven.
