The Certainty of Bad
Breath
We can be certain we'll have bad breath some time
but do you know the causes of bad breath? You are
familiar with the joys of bad breath- wake up with nasty
morning breath, or have the stinky breath that's a result of
eating too much garlic or onions, or have family step back a
pace when we go to give them a kiss. Unless you are
actively eating food that causes bad breath, you probably don't
know what the cause of halitosis is.
Our mouths are teaming with bacteria, bacteria that are
supposed to be there, all of them breaking down and digesting
food and doing other necessary things. The bacteria that
causes bad breath is known as anaerobic bacteria. These
are bacteria that thrive in areas without oxygen, especially
under the surface of the tongue and at the back of the
throat.
They specialize in breaking down and digesting
proteins. Proteins are made up of amino acids, two of
which are Cysteine and Methionine, These two amino acids are
high in sulfur. As these anaerobic bacteria digest the
proteins, the resulting waste products have a bad sulfurous
smell. Welcome to the world of bad breath!
The waste products created are known as Volatile Sulfur
Compounds or VSC. The volatility means that the VSC are
easily carried away on a breath, out to where other people can
detect them. The two compounds that smell like sulfur are:
Hydrogen Sulfide
Methyl Mercaptan
Unfortunately, there are other waste products that add to
smelly breath:
Cadaverine - this is the smell of decaying bodies.
Putrescine - this compound causes much of the odor of
decaying meat.
Skatole - this compound smells similar to human
feces.
Isovaleric Acid - this compound smells similar to sweaty
feet.
No one is immune. Even babies can have bad breath. You
may be wondering if everyone has these bacteria and not
everyone has bad breath, what is causing bad breath for
some?
There are several things that lead to more anaerobic
bacteria and/or more of their waste products being created.
The surface of our tongue is covered with papillae which are
tipped with tastebuds. Anaerobic bacteria can be found in
between these papillae. If you tongue is coated - go look
in the mirror - that will cut down on the oxygen getting
between the papillae. Even a coating as thin as 0.1 or
0.2 millimeters is thick enough to keep out the oxygen.
This is also the case with plaque on your teeth. A very
thin coat of plaque will keep oxygen from reaching areas around
the gums and between your teeth, creating more places for
anaerobic bacteria.
Saliva helps keep your mouth oxygenated. Dehydration
will reduce the levels of oxygen, so drinking more water and
less coffee and alcohol will help fight chronic haltosis.
Smoking will dehydrate the mouth, so not all of smokers breath
comes from just the smell of tobacco. Certain medications
also are dehydrating.
High protein diets increase the amount of protein that can
be converted to VSC's. Sinus and allergy conditions that cause
post nasal drip will also add protein-rich mucus to the back of
the tongue and throat.
Even standard dental products can help cause bad breath
rather than be the
bad breath remediesthat we hope they will be.
Many mouthwashes contain alcohol, which is deydrating. Even
toothpaste is not without it's problems. The majority of
popular toothpastes contain sodium lauryl sulfate, the
detergent in shampoo and soaps that makes them and your
toothpaste bubble and foam. This detergent does nothing
to eliminate anaerobic bacteria and can be damaging to the
lining of your mouth.
There you have it. The primary cause of bad breath for
the average person is the anaerobic bacteria that live in your
mouth. Most people associate a coated tongue with bad
breath, and they would be right. It's not the coating but
what it covers that matters.
