An unpleasant odor detected during interdental cleaning often indicates the presence of trapped food particles and bacterial buildup in the spaces between teeth. This malodor is a consequence of anaerobic bacteria metabolizing organic matter, releasing volatile sulfur compounds (VSCs) as byproducts. Examples of such compounds include hydrogen sulfide, methyl mercaptan, and dimethyl sulfide, which are known for their characteristic foul smells.
Addressing this issue is crucial for maintaining optimal oral hygiene and overall health. Regular and effective interdental cleaning removes the substrate upon which bacteria thrive, thereby reducing VSC production. Consistent practice helps prevent the progression of gingivitis and periodontitis, conditions linked not only to halitosis but also to systemic diseases. Historically, rudimentary forms of interdental cleaning have been practiced across cultures, highlighting a longstanding awareness of the importance of removing debris from between teeth.
