Breath spray is a product sprayed into the mouth for the purpose of eliminating or covering up halitosis. It is occasionally advertised as being for smokers or those who dip tobacco, and occasionally to cover up the smell of cigar smoking. It comes in a number of brands, such as Binaca. Common flavours include cinnamon, spearmint and peppermint, as well as company-specific flavours such as "Ice Mint".
Some breath sprays have an anti-bacterial or anti-plaque property; some others contain chlorine dioxide As alcohol is frequently a prime ingredient of breath sprays, some brands advertise that they are alcohol-free.
There has been wide diversity in packaging design; customised breath-spray containers have been made with the University of Michigan name on them, and Mother Teresa breath spray is also available. Other novelty packaging includes that of "Instantly Monogamous Breath Spray," and there is a joke breath spray called "Instant Gay Accent."
Breath spray is also called "tongue spray".
