Chew gum like it's going out of style.
Believe it or not, saliva is your best weapon against bad breath. That's why dry mouth, often caused by certain medications or medical conditions, leads to odor problems. By washing away food particles and bacteria, saliva helps to eliminate odor, too.
If you're wondering why your breath stinks in the morning, it's largely because saliva production slows while you sleep, allowing particles and odor to linger longer. That's where sugarless gum comes in handy, as chewing it will stimulate saliva production. Mints, on the other hand, don't usually stimulate saliva production and only temporarily mask bad odor.
"When you chew gum it makes you salivate, and the more saliva you have in your mouth the fewer bacteria you have. It not only mechanically washes bacteria out, but we have antiseptic and enzymes in our saliva that kill bacteria," says Wolner.
While anything that makes you salivate will improve your breath, a gum that is sweetened with xylitol is your best option. Xylitol is a sugar substitute that not only increases salvation but also works to prevent bacteria from replicating in the mouth.
