The mouth including your teeth is the first place where food gets broken down into useable pieces for your body to use.
When the foods you eat become digested they are carried by your bloodstream to other parts of your body including your lungs where they foods then are given off as bad breath when you talk or exhale.
When you eat really strong foods such as when you bite into an onion or eat foods containing garlic you can then have bad breath. Try; as you might to cover up your bad breath with mouthwash, by brushing or flossing the end product is still going to be bad breath until the last part of the food has passed from your system.
Taking these commercial products may cover up the bad breath for a while, but the source (the food you’ve eaten) will still be there in your body.
What poor habits can possibly cause bad breath?
We all form habits as we go through life. Some habits are good and some are not so good for our health. The habit of not brushing and not flossing can lead to dental cavities that can cause us to have bad breath.
People who have the habit of ignoring poorly fitting dentures can also breed bacteria that cause bad breath.
Individuals that practice the bad habits of smoking, chewing tobacco-based products can also not only cause bad breath but also cause teeth staining and reduce the ability for them to taste the food they eat.
Tobacco products can also irritate the gums causing bacteria to congregate which will in turn cause your breath to smell.
Health problems can also cause bad breath:
Certain health issues can cause bad breath and bad breath can even signal gum disease which is a buildup of plague on the surfaces of your teeth. If the individual is not treated for gum disease than it can damage the jawbone and gums.
This is why it is so important to recognize, prevent or treat bad breath as doing so can alleviate pain and suffering later on.
Other health issues associated with bad breath include dry mouth which you may see expressed in medical terms as, "xerostomia", pneumonia, bronchitis, chronic sinus infections, chronic acid reflux disease, liver or kidney disease, diabetes and also the occurrence of postnasal drip.
