8 Causes of Bad Breath

8 Causes of Bad Breath

Bad breath is probably one of the annoying things that could happen to us. It also can affect our confidence and mood throughout the day. People try to get rid of it or hide it as best as they can. Usually, people would brush their teeth to get rid of bad breath. But actually, brushing alone may not be able to get rid of bad breath.

To get rid of bad breath, you need to know the causes of the same. Scientists are still studying the causes of bad breath, and here are few findings from it:


healthy reason to drink coffee

If you notice that your breath seems stale after your morning break, it could be the result of your daily rituals. Caffeine in your coffee will dry your mouth out, and the more you drink, the worse the problem will get. Cutting out your daily intake of coffee may help to reduce bad breath.


It is quite clear. Smoking causes its own unpleasant mouth odor. Smokers and oral tobacco users are also more likely to have gum disease, which is another source of bad breath.

Bad bacteria

Your mouth is home to both good and bad bacteria. The bad bacteria is one of the causes of bad breath, and studies show that one in particular, H. Pylori, is linked to bad breath. Those bacteria mostly live on the tongue; so make sure you brush your tongue each time you brush your teeth.

Skipping breakfast

Breakfast is not only important for your energy, but also for your fresh breath throughout the day. When you skip your breakfast, your saliva glands aren’t as active in the morning. This can dry your mouth and causes bad breath. Even if you brush and gargle before leaving the house, your breath will not be as fresh as it would be if you had eaten breakfast. That’s why; NEVER SKIP YOUR BREAKFAST!

Chewing gum

Usually, as soon as you notice your breath is bad, you pop some gum in your mouth, thinking that it will cure the problem. Studies show that only sugar-free gum sweetened with Xylitol can prevent bacteria that cause bad breath and cavities.

Breathing through your mouth

Some people breathe through their mouths only when they are too stuffed up to breathe through their noses. Others, however, have fallen into the habit of breathing through their mouths all the time. When your mouth is open for long periods of time, it dries out and a dry mouth is one of the causes of bad breath.


Protein-rich foods are one of the food trends right now. Protein is necessary for your body and very good for you, but like anything else, too much of a good thing is not good. If you are limiting your carbohydrates and filling up on protein, it will have an effect on your breath. So if you’re trying to lose some weight but are not enjoying the bad breath, try a more balanced diet instead and add in some exercise.

Lack of fruits and vegetables

If you don’t eat enough fresh fruits and veggies, it can cause bad breath. Fresh produce is the best choice because your mouth will have to increase saliva production to chew and digest the fruits and vegetables, and the extra saliva will clean odor causing bacteria out of your mouth.
