Bad breath does not always stem from eating certain foods--it can be the result of something going on internally. Internal bad breath often comes from sinus infections, bacterial activity in your digestive system, low-carbohydrate diets, or simply not eating. If you notice your breath is unpleasant even after brushing and flossing your teeth, your bad breath may indicate that something else is going on with your body. There are home remedies that work well to keep internal bad breath at bay.
Food particles that linger in your mouth after you eat can lead to bacterial growth, which causes internal bad breath. Drinking plenty of water and keeping your mouth moist washes away these food particles and helps to minimize bad breath. A dry mouth also facilitates bacterial growth; chewing gum or sucking on hard candy stimulates saliva production, which also aids in washing away food particles and bacteria.
Eating smaller, frequent. well-balanced meals throughout the day can de-stress your digestive system and improve its functions, reducing internal bad breath. Eating fresh vegetables and incorporating fiber into your diet keeps your digestive system working properly and keeps you regular, another important part of healthy digestion.
Bacterial activity in your digestive tract can cause bad breath, especially if your system is not functioning properly. You can knock out the bad bacteria and replace it with good bacteria, which is what probiotics do, as they include the appropriate sources of nutrition to encourage good bacteria to grow, re-invigorate and repopulate your intestinal flora.
Sinus infections often cause internal bad breath because they increases the amount of mucus and bad bacteria that can grow in it. The mucus protects bad, or anaerobic, bacteria from exposure to oxygen, in which they cannot survive, thus allowing the bacteria to thrive and produce bad-breath odors.
Use a tongue scraper to brush your tongue daily. This will remove odor-causing bacteria from your tongue, getting rid of one possible source of internal bad breath.
