Approaches to improve bad breath may include physical or chemical means to decrease bacteria in the mouth, products to mask the smell, or chemicals to alter the odour creating molecules. Many different interventions have been suggested and trialed such as toothpastes, mouthwashes, lasers, tongue scraping, and mouth rinses. There is no strong evidence to indicate which interventions work and which are more effective. It is recommended that in those who use tobacco products stop. Evidence does not support the benefit of dietary changes or chewing gum. Mechanical measures Brushing the teeth may help. While there is evidence of tentative benefit from tongue cleaning it is insufficient to draw clear conclusions. A 2006 Cochrane review found tentative evidence that it might decrease levels of odour molecules. Flossing may be useful. Mouthwashes A 2008 systematic review found that antibacterial mouthrinses may help. Mouthwashes often contain antibacterial agents including cetylpyridinium chloride, chlorhexidine, zinc gluconate, zinc chloride, zinc lactate, hydrogen peroxide, chlorine dioxide, amine fluorides, stannous fluoride, hinokitiol, and essential oils. Listerine is one of the well-known mouthwash products composed of different essential oils. Other formulations containing herbal products and probiotics have also been proposed. Cetylpyridinium chloride and chlorhexidine can temporarily stain teeth. Underlying<unk>  If gum<unk>  and cavities are present, it is recommended that these be treated. If<unk> s outside of the mouth are believed to be contributing to the problem, treatment may result in improvements. Counselling may be useful in those who falsely believe that they have bad breath.
