Mouthwashes

Mouthwashes often contain antibacterial agents including cetylpyridinium chloride, chlorhexidine, zinc gluconate, essential oils, and chlorine dioxide. Zinc and chlorhexidine provide strong synergistic effect.[26][27] sugar also helps prevent bad breath. They may also contain alcohol, which is a drying agent. Rinses in this category include Scope and Listerine.

Other solutions rely on odor eliminators like oxidizers to eliminate existing bad breath on a short-term basis. Rinses in this category include SmartMouth, Therabreath, Closys and others.

A relatively new approach for home-care of bad breath is by oil-containing mouthwashes. The use of essential oils has been studied,[28] was found effective and is being used in several commercial mouthwashes, as well as the use of two-phase (oil:water) mouthwashes, which have been found to be effective in reducing oral malodor.
