Bad Breath

Bad breath (or as it’s known scientifically – halitosis) is a bad, often offensive odor coming from the sufferers mouth. The causes are many and we’ll look at those later but, if you have ever suffered from bad breath or been close to someone with bad breath – then you know that this can be embarrassing and dramatically effects the way we react and interact.

The Causes of Bad Breath

There are many reasons why you may suffer from bad breath. There may be an underlying medical condition or perhaps it’s something in your life style. If you suffer from this unpleasant condition, we recommend that you consult your family physician or dentist.

Some common causes of bad breath include:

  • Poor mouth cleaning regime and techniques.
  • If you suffer from tooth decay and gum disease.
  • Certain foods.
  • Smoking (cigarettes and pipe).
  • Alcohol.
  • Use of drugs or medicines that create a dry mouth.
  • Infections of the mouth.
  • Stomach problems.

If you fail to brush your teeth and clean your mouth properly this can lead to the development and growth of harmful bacteria on leftover food deposits lodged between the teeth. As these deposits decay, they may produce an unpleasant feeling inside the mouth and a bad odor.

Failure to brush your teeth regularly can also lead to a buildup of plaque which generates an unpleasant smell.

The tongue is another source of bad breath. Bacteria develop and multiply on the tongue and, if not treated, lead to bad breath.

Many different foods are associated with halitosis. These include, garlic, onions, curry, fish, coffee (yes coffee!) and some cheeses. Bad breath caused by food is usually a transitional phenomenon and one that is easily treated by a change of diet.

Health problems

It’s well known that a variety of ailments can cause bad breath. The common cold can lead to a sinus infection where bacteria spread to the mouth and the throat causing an unpleasant odor.

 Stomach problems can also cause bad breath problems. Stomach ailments often involve the release of gases from the stomach which can travel up into the mouth cavity causing bad breath.

The key is a proper diagnosis

If you suffer from chronic halitosis, then the best solution to obtain a professional diagnosis from your dentist or physician. It is vital, as with any medical consultation, to be totally open and honest with the dentist or doctor who is examining you. They need to be aware of all the facts so that they can fully understand the health problems you may have. This enables them to accurately identify and diagnose the causes and then initiate the appropriate course of treatment.

One of the more common clinical devices used to diagnosis halitosis is the Halimeter (portable sulfide gas monitor). The Halimeter measures the quantities of hydrogen sulfide in the mouth in parts per billion (ppb). Using a patented electrochemical voltammetric sensor, the Halimeter has provided doctors and dentists reliable and reproducible results for more than 20 years and has been demonstrated many, many times on TV programs such as The View, Good Morning America, and CBS Morning News by Dr. Harold Katz.

Getting correct and effective treatment

For more than a century, drug companies tried to find a solution for the problems of halitosis by encouraging the use of an alcohol based mouthwash. In fact, because alcohol tends to dry out the mouth and restrict saliva production, it was a counterproductive “solution”.

Over the years, dentists and doctors have learnt a lot about halitosis and its causes and treatment. Today, providing the symptoms and causes are understood, finding the correct treatment regime is usually possible.


The bacteria that are responsible for bad breath are a natural part of the body’s functioning and, in the right concentrations, are essential for our oral health. They are part of your oral flora and of the digestive process that breaks down proteins.

No amount of brushing, flossing or scraping can or should get rid of them. However, if you do suffer from bad breath, regular and proper oral hygiene can provide a temporary solution. However, for all those who feel that oral hygiene is all that is required to keep the problem “under control”, this can be very annoying and frustrating.

Today, there is a much simpler and clinically recognized treatment for halitosis. It involves interfering with the bacteria’s ability to chemically produce undesirable smells through the use of oxygenating compounds. Remember, anaerobic bacteria thrive in an oxygen free environment and, in fact, the introduction of oxygen into their environment is lethal to them.

A common halitosis treatment includes the use of mouthwashes and toothpastes, recommended by your dentist, that contain oxidizing agents such as chlorine dioxide or sodium chlorite which neutralize and control the sulfur compounds responsible for bad breath.

In the event that you’re suffering from a dry mouth, then your dentist will most probably prescribe a saliva substitute that you can use during the day to prevent a dry mouth. It’s also worthwhile, when looking for off the shelf oral care products, to see if they contain natural ingredients such as zinc gluconate, aloe vera, green tea, tea tree oil, xylitol, CoQ10, glycyrrhizic acid and oral probiotics such as K12 and M18
