Oral malodor often originates from dental biofilm, a sticky film composed of bacteria, food debris, and saliva that accumulates on teeth and gums. The unpleasant odor associated with this buildup arises primarily from the metabolic activity of anaerobic bacteria within the biofilm. These microorganisms break down proteins and other organic compounds, releasing volatile sulfur compounds (VSCs) as byproducts.
The presence of foul-smelling emanations from oral biofilm highlights the importance of meticulous oral hygiene practices. Regular brushing, flossing, and professional dental cleanings disrupt the biofilm, limiting the proliferation of anaerobic bacteria and minimizing the production of VSCs. Historically, methods for addressing oral malodor have evolved from rudimentary teeth cleaning techniques to sophisticated oral care products designed to target biofilm and its odor-causing byproducts.
