One way to prevent severe bad breath is to practice proper dental hygiene by brushing your teeth and tongue; however, if bad breath persists in spite of diligent mouth care, some natural remedies include green or black tea, water, apple cider vinegar, baking soda and tea tree oil. A dentist can diagnose and treat potentially dangerous causes of bad breath, such as tooth decay, gingivitis or oral ulcers.
Green or black tea can help eliminate bad breath by killing the bacteria that cause the problem. These teas contain antioxidant polyphenol compounds called flavonids that inhibit bacterial growth. Scientists have discovered that tea also suppresses the chemical compounds that create foul breath. Studies have shown that black tea can keep plaque from growing on teeth; therefore, drinking black tea can help prevent tooth decay and halitosis.
Another simple home cure for bad breath is drinking plenty of water. Halitosis-causing bacteria thrive in dry mouths. Drinking water helps flush out these bacteria and any food particles that remain in the mouth after eating. For those who suffer from chronic dry mouth, sucking on mints or chewing gum can help stimulate saliva; doctors can also prescribe medications to treat the condition.
Apple cider vinegar is a popular home remedy for many conditions. The vinegar, which is made from crushed fermented apples, kills bacteria, which cannot tolerate acid. To treat bad breath, rinse your mouth with a mixture of apple cider vinegar and water after brushing your teeth. Baking soda also changes mouth acidity to kill bacteria; prepare a mouthwash by mixing baking soda and water, or choose a toothpaste that contains baking soda.
