When a cold prevents you from breathing through your nose, you’re forced to inhale and exhale through your mouth. This dries out the tissues and reduces the flow of saliva—the mouth’s built-in cleanser, which not only rinses away food particles but also neutralizes decay-causing acids and acts as a natural antiseptic to keep bacteria in check. The lesser the saliva, the more the bacteria—and the more potent the odor. An easy remedy (for your breath, if not your cold): Chewing gum—as long as it’s sugarless—has been shown to increase the flow of saliva.
Your Movie Treats
Bacteria have a sweet tooth, too. When you eat sticky candy like gummy bears, cherry vines and even mint chews, the bacteria “has a party,” says Kimberly Harms, DDS, the consumer adviser for the American Dental Association. It feasts on the sugar and spreads to all areas of your mouth—including hard-to-reach areas in the grooves of the teeth. But here’s a surprise: Dentists have started recommending chocolate as a more healthful alternative to candy. Harms says that chocolate not only dissolves relatively quickly but also has less sugar than other candy, as well as a small amount of calcium to protect enamel.
Yep. Many brands of mouthwash and antibacterial mouth rinse contain alcohol—sometimes accounting for as much as 27 percent of total ingredients—that dries out your mouth, leaving a stale smell after the minty freshness wears off in an hour or so. Look for brands with no or little alcohol and save them for first dates or job interviews (or when recommended by a doctor).
Your Gram Negatives
Of all the different types of bacteria that live in your mouth, the most pungent, by far, are a kind called ‘gram-negatives’. Not only do they produce gassy-smelling sulfuric compounds, but they also have an extra cell layer that makes them especially resilient. They burrow down below the gum line and hide out in the crevices of the tongue. Flossing helps remove them, but another option is brushing your tongue, which has been shown to reduce bad breath by 70 percent. Clean your entire tongue, especially the back where more there are more peaks (or papillae) and valleys as well as the cheeks, recommends Gary H. Westerman DDS, a professor of dentistry at Creighton University. You can also use a toothbrush or a drugstore tongue-brush, but an Orabrush has longer, softer bristles as well as a scraper to collect the bacteria once it’s been dislodged.
Your heart is pounding, your palms are sweating, you’re practically panting with stress—and your mouth is probably not smelling that great (aargh, dry mouth again!). In addition to taking a few calming inhalations, remember to take several rehydrating, breath-freshening sips of water.
The cure…a glass of milk
Finally, a cure for garlic breath. Drinking milk can lower the concentration of odor-emitting compounds from garlic in the mouth (and nose), Ohio State University researchers recently discovered. Whole milk seemed to be slightly more effective than skim (due to the absorbent fat) and had the most noticeable results when it was consumed during a meal (although drinking a glass afterward can help too).
