The practice of a few, simple, self-care techniques can help to minimize halitosis. There are several things you can do at home.
Advanced oral care products: Use oral care products such as mouthwashes and toothpastes that have been shown to be effective in fighting bad breath.
Proper oral care: Brush and floss your teeth at least twice a day. Be sure to get a toothbrush with soft bristles (as to not damage tooth enamel or gums) and also use fluoride toothpaste. Brushing and flossing helps to remove any food and plaque which can be used as a fuel source by the anaerobic, sulfur-producing bacteria that are at the root of this problem.
Stimulate your salivary flow: Prevent dry mouth with chewing gum, lozenges, or mints that are sugar free. Look for Xylitol, a non-sucrose sweetener, which in recent years has been shown to have anti-cavity properties.
Drink plenty of water and swish cool water around in your mouth. This is especially helpful to freshen “morning breath.”
Eat fibrous fruits and vegetables: One of the best ways to remove bacteria in the mouth is to eat an apple a day. It helps moisten the mouth, too.
If you wear dentures, remove them at night and clean to get rid of bacterial buildup from food and drink.
Take a dietary supplement: Vitamin C, Vitamin D, Vitamin E, and Vitamin B are effective at helping your body eliminate excess mucus and toxins naturally.
Brush your teeth occasionally with baking soda: The bacteria that cause bad breath thrive in an acidic oral environment. Brushing your teeth with baking soda helps neutralize excess acids found in the oral cavity.
Ask your doctor if a medication could be fouling the air you expel. Any drug that dries out your mouth, thereby depriving it of saliva, is suspect. These include over-the-counter antihistamines, decongestants, diet pills, and prescription medications for depression and high blood pressure.
