Which hygienic practice can effectively reduce halitosis?

Regular brushing and flossing, along with tongue scraping, effectively reduce halitosis because these practices target the major contributors to bad breath. Regular brushing of the teeth removes food particles and plaque from the surfaces of the teeth, helping to prevent the buildup of bacteria that can produce foul-smelling compounds. Flossing is equally important, as it removes debris and plaque from between teeth, areas that a toothbrush cannot reach effectively.

Tongue scraping addresses a specific cause of halitosis: the accumulation of bacteria and food debris on the surface of the tongue. The tongue can harbor a considerable amount of bacteria that contribute to bad breath, particularly towards the back where it can become more difficult to clean. By incorporating tongue scraping into a daily oral hygiene routine, individuals can further reduce the source of the odor.

While mouthwash can provide a temporary freshening effect, it typically doesn't address the underlying causes of halitosis on its own. The elimination of sugary foods can help reduce the overall risk of tooth decay and, indirectly, bad breath, but it is not a direct hygienic practice aimed at managing halitosis itself. Thus, combining regular brushing, flossing, and tongue scraping offers a comprehensive approach to tackling this issue effectively.
