Acute Sinusitis - an infection that usually lasts for about 3 weeks. It is often triggered by the flu or cold. The flu or cold virus attacks your sinuses causing them to swell and become narrow. Your body responds to this virus by producing mucus. When the sinuses become blocked and are filled with mucus, viruses, fungi or bacteria can grow and cause infections. That causes more mucus build-up, pressure and intense headache, toothache or bad breath.

Symptoms of Bad Breath
One may not always know that he/she has bad breath. It is because the olfactory nerves (odor-detecting cells) in the nose eventually get used to the smell and do not let the person know of anything odd. But, other people come to notice this foul odor instantly. One can get make a judgement that he/she has bad breath if he/she notices people stepping away while one are speaking. Also, it can be easily judged from peoples' reaction, if they are uncomfortable talking because of one's bad breath.

Home Remedies for Bad Breath
Brush After Every Meal
Some odors can be eliminated if you brush immediately after the meal. Bad breath is largely result of soft, sticky film of living and dead bacteria on teeth and gums. At any time, there are about 50 trillion microscopic organisms in mouth. Therefore, it is advised to brush thoroughly after every meal to keep the concentration of these bacteria on a lower side, and avoid bad breath.

Home-made Gargle
Mix extracts of sage, calendula, and myrrh gum in equal proportions and gargle with the mixture at least four times a day. Keep the mouthwash at room temperature in a tightly sealed jar.

Rinse Frequently
Rinsing frequently flushes out the bacteria from mouth and keeps their concentration low. Even when you can not brush, just go ahead and rinse your mouth thoroughly. Take a sip of water after meals, swish it around, and rinse thoroughly to wash the smell of food from your mouth.

Spices
Spices in kitchen are natural breath enhancers, especially cloves, anise seeds, fennel, etc. can be consumed after odoriferous meals to keep away bad breath. These spices have strong fragrances of their own and overpower the foul smell of bad breath. It is also advised to carry a tiny plastic bag of spices along whenever out of home.

Brush Your Tongue
Tongue has several hair-like projections which acts as room to harbor plaque and bacteria along with the things we eat. All of this can result in bad breath. Therefore, it is advised to clean tongue thoroughly with a tongue cleaner every time you brush your teeth. Doing this on a regular basis will keep bad breath away.

Avoid Certain Beverages
Beverages like coffee, beer, whiskey, wine, etc. are at the top of the list of offenders. Each of these beverages leaves a residue that can attach to the plaque in mouth and infiltrate the digestive system. Each breath you take spews traces back into the air. Therefore, it is advised to avoid these aforementioned beverages to keep away bad breath.
