Rinse your mouth out.
When you can not brush, you can rinse. GO to the restroom after meals and get a mouthful of water, swish it around and wash the smell of food from your mouth Spit the water out, of course

Eat three meals a day:
Bad breath can be caused by not eating too. One of the side effects of fasting or a poor diet is bad breath

Swish and swallow
You are in a restaurant, and your brush and floss are at home. You can not excuse yourself form the table, so take a sip from your water glass and discreetly circulate the water across and around your teeth. Then swallow those potentially offending bits of food.

Gargle a minty mouthwash
If you need 20 minutes of freedom from bad breath, gargling with a mouthwash is a great idea. But like cindrella’s coach-turned-pumpkin, when your time is up, the magic will be gone and you will be back to talking behind a hand again Choose your mouthwash by color and flavor. Amber and medicine flavored mouthwashes contain essential oils such as thyme, eucalyptus, peppermint and wintergreen. Red and spicy mouthwashes may contain zinc compounds. Both types will neutralize the odor-producing wast products of your mouth bacteria.

Chew a mint or some gum.
Like mouthwash, a breath mint or minty gum is just a coverup, good for a short interview a short ride in a compact car, os a very short date

Eat your parsley.
Parsley adds more than green to your lunch plate, it is also a breath savor. Parsley can freshen your breath naturally. So pick up that sprig and chew it thoroughly.

Spice is nice
Certain herbs and spices you keep in your kitchen are natural breath enhancers. Carry a tiny plastic bag of cloves, fennel, or anise seeds to chew after odorous meal

Brush your tongue
Most people overlook their tongues, your tongue is covered with little hairlike projections, which under a microscope look like a forest of mushrooms. Under the caps of the mushrooms there is a room to harbor plaque and some things we eat. That cause bad breath
