More than 100 kinds of bacteria live inside your mouth, and when you don't floss they feed on the leftover food particles left behind. In doing so, the bacteria emit sulfur compounds that produce unpleasant odors.
American Dental Association answeredThere are many factors that can lead to bad breath and not flossing is one of them. When you don't floss, tiny bits of food can remain in your teeth and can lead to bad breath. If you are concerned about what’s causing your bad breath, you should make an appointment to see your dentist right away. Regular checkups allow your dentist to detect any problems such as gum disease or dry mouth, which can both contribute to bad breath. Maintaining good oral hygiene, eliminating gum disease and scheduling regular professional cleanings is essential to reducing bad breath.

Not flossing your teeth is like only washing the outside of a glass and not the inside. Left over food/drink begin to putrify creating a feeding ground for bacteria. The longer the bacteria are in your mouth, the more likely they are to cause inflammation and product a sulfur-like odor. To prevent this from happening, clean between your teeth every day with a product you like and feel comfortable using; string floss, toothpick, interproximal brush or a water flosser. All work as well as traditional floss.
