You can change your daily habits to combat bad breath in the following ways:

- Brush your teeth and tongue regularly

- Floss daily to remove tiny food particles between your teeth

- Rinse with mouthwash to lock in the freshness

- Drink plenty of water

- Avoid smoking

- Beaware of smelly foods for example garlic and onion

The mouth is filled with bacteria, and more often than not, a dirty mouth is what causes bad breath. 

Food often gets trapped between the teeth and along the gum line, which then becomes a breeding ground for bacteria. When this area is not cleaned, bad breath occurs. 

Another common cause is eating food that has a strong odor, such as garlic, onions, and even alcohol. These types of food create a bad odor in your mouth, and some of them are absorbed by your body and enter the bloodstream, causing you to breathe the odors through your lungs. 

Occasionally, bad breath can be a sign of a serious illness, such as diabetes, liver failure or kidney disease.

Visiting your dental hygienist for professional cleaning, brushing your teeth after every meal, flossing at least once per day, and using mouthwash regularly can reduce or eliminate bad breath in many cases. 

Suppose your bad breath results from a chronic issue such as tooth decay or illness. In that case, you'll need to see a healthcare professional because gum and mouthwash will only mask the problem for a little while. 

In most cases, the prognosis for chronic halitosis is good.

Taking steps to determine the cause of your bad breath, improving oral care, and changing diet and habits can lead to fresher breath, and that's something to smile about!
