You can use commercially available breath fresheners or mouth washes for temporary relief from bad breath. However, most of them are temporary and act by masking the smell producing layers of tongue, once the effect wears off, the bad breath will resurface with renewed vigor.
Using anti-bacterial mouth rinses may provide you better results in controlling bad breath. Always avoid alcohol containing mouth rinses as alcohol is a drying agent and will worsen the problem sooner or later.
Acute bad breath may be temporarily controlled by using a hydrogen peroxide rinse in your mouth. Hydrogen peroxide at a minute concentration of 1.5% can be taken as an oral antiseptic by gargling 10 ml, for a few minutes.
Hydrogen peroxide is commonly available at a concentration of 3% and should be diluted to 1.5% by mixing it with an equal volume of water.
Hydrogen peroxide is a powerful oxidizer which kills most bacteria, including useful aerobic bacteria.
Evidence suggests the most effective products are generally unavailable in drugstores and usually found on the internet pharmacies.
Top of the brand home breath tests and antibacterial rinses, toothpastes, gums, mints, and tongue gels are always costlier like any premium product; but unlike the well-known inexpensive brand names, they can really control your problem to a marked degree.

Never forget to brush your teeth after meals and a regular flossing at least once in a day will remove putrefying food debris from between the teeth, especially at the gum line and posterior of the tongue.
Gently cleaning the tongue surface twice daily with a tongue brush, tongue scraper or tongue cleaner will help you keep your tongue and teeth in good shape and health.
Alternatively, you can also use an inverted teaspoon to scrap the surface of your tongue. Tooth brush will not work well in scraping the back of your tongue as the bristles will not reach the back parts of your tongue. Be careful to avoid scraping the V-shaped row of taste buds found at the extreme back of the tongue. Brushing a small amount of antibacterial mouth rinse or tongue gel onto the tongue surface will further inhibit bacterial action.
Since a dry mouth can increase bacterial buildup and cause or worsen bad breath, chewing sugarless gum can help with the production of saliva, and thereby help to reduce bad breath. Some gums, toothpastes, sprays, and gels which combat dry mouth for several hours have recently been marketed over the counter.
Maintain water levels in the body by drinking several glasses of water a day. Adding lemon juice to your water is refreshing and also beneficial. Parsley is a natural breath freshener when chewed slowly, and is easy to grow at home.
