Bacteria cause of bad breath

Saliva keeps bad breath at bay because it is rich in oxygen. The bacteria that lead to symptoms of bad breath are anaerobic bacteria, meaning they live in an environment that does not have oxygen. When you have a dry mouth you're creating an environment that is more similar to their home, one that has little oxygen. So the bacteria thrive, and so does bad breath.

Excess bacteria in your mouth have now been found to cause more than tooth decay, gingivitis or gum disease. So, you need to know, even though you might not have gingivitis, how to control these plaque-building bacteria in your mouth.

Bacteria that create gingivitis live in your plaque and cause your gums to inflame, bleed, and separate from your teeth. You can also have bad breath when you have gingivitis. In more severe cases, your gums become sore, teeth hurt, gums recede, and teeth loosen.

Certain foods that are high in protein like meat, and for those who are lactose intolerant, dairy. If you don't digest dairy products well, the bacteria have more of a chance to digest the proteins in milk and produce the volatile sulfur compounds that result in bad breath. Similarly, if you don't floss after a meal, especially if you've eaten meat, the bacteria in your mouth have ample time to break down the meat proteins stuck between your teeth. Inorder to stop bad breath and bacteria in your mouth, brush your teeth when you wake up in the morning and going to bed.
