Halitosis Treatment

What is Halitosis?

Halitosis is the scientific name for chronic bad breath, remains after the use of mints or regular mouthwash and can be an indicator or a more serious problem.

How do I know if I have Halitosis?

Apart from the use of a Halimeter, you can test your own breath by licking the back of your hand, leaving it to dry and then smelling it to see if you have bad breath.

Why does Halitosis smell so bad?

Halitosis is caused by the buildup of bacteria in the mouth and throat that consume protein. The by-product is a sulfur compound which smells so bad.

After brushing my breath smells!

This can be a sign of gum disease which should be diagnosed by a dental hygienist or dentist. Healthy gums are essential for Fresh breath.

Can I "catch" bad breath?

If your partner has bad breath and your mouth is clean and healthy, it is very unlikely that the bacteria will be able to thrive in your mouth.

Dr Katz Therabreath since 1994

Dr Katz has been helping people with bad breath and Halitosis since 1994 in response to his daughters bad breath that was causing her considerable embarrassment.


Halitosis is the scientific name for bad breath, nothing more, nothing less. Everyone at some stage in their life has had bad breath but it is those who suffer from persistent Halitosis and become self conscious of the foul smell that it starts to effect their everyday interaction with people both socially and in the workplace that we need a cure that will restore confidence.

What causes Halitosis?

Halitosis is caused by an accumulation of sulphur producing anaerobic bacteria in the oral cavities (mouth, throat sinuses). These anaerobic bacteria feed on proteins like food particles, mucous or blood and the by product of their consumption of available proteins is a sulphur compound which we experience as Halitosis.

The causes for the accumulation of these anaerobic bacteria or environments which allow the bacteria to multiply are most commonly dry mouth, corrugated tongue where protein particles can get trapped, in the nooks and crannies on your tonsils and back of your tongue or in the sinuses.

Dry mouth and as a result, Halitosis is often experienced by people taking anti-depressant medication, antihistamines or birth control pills. Bad breath is not an illness, it is simply an accumulation of anaerobic bacteria that give off hydrogen sulphide and can be effectively managed by increasing the concentration of Oxygen rich saliva and Therabreath products do just that, create oxygen rich environments that eliminate anaerobic bacteria as an effective cure for Halitosis. You do not need to Live with Halitosis.

Therabreath was developed in 1994 by Dr Harold Katz of the California breath clinics in response to a bad breath condition his 13 year old daughter experienced. Dr Katz is a Dentist and founder of the California breath clinics and has personally treated many thousands of people suffering with Halitosis ranging from mild to moderate Halitosis to Chronic and severe Halitosis .

Dr Harold Katz has appeared on most News channels and has become known in Hollywood as “The bad breath Guru”

Halitosis is most severe in the early mornings when you wake up due to the bacteria being active for a long period of time while you were asleep. You may also experience more severe Halitosis at the end of the day if you have been drinking coffee and not eating regularly. People who talk a lot for a living like sales people or receptionists are also more prone to having halitosis simply because the action of talking allows their mouths to dry out a lot quicker than others.

Banish morning breath with Therabreath’s Halitosis cure. The cure for Halitosis is to create oxygen rich environments which are not conducive for anaerobic bacteria to thrive in. Therabreath causes a chemical reaction in your mouth which produces high doses of oxygen and stimulates the production of oxygen rich saliva, effectively keeping the anaerobic bacteria under control allowing you to feel confident all day long. Don’t let Halitosis effect your social life, there is a cure for Halitosis that will allow you to start living a fresh breath life and enjoying social interactions once again.

What are tonsil stones and why do they smell so terrible?

If you still have your tonsils you may have noticed a terrible smell which seems to be coming from the back of your throat and from time to time you feel a scratchy sensation at the back of your throat which, when you are able to cough them out, smell so foul you feel like retching.

These are commonly known as tonsil stones with a scientific name of Tonsilloliths. Tonsil stones are an accumulation of mucous and bacteria that lodge themselves in the nooks and crannies at the back of your throat and on your tonsils and only occur in people who still have their tonsils. Don’t rush out to have your tonsils removed, you can effectively treat tonsil stones now that we understand what they are and how they are caused. If you suffer from Post nasal drip the chances are that you suffer from Halitosis and thanks to Dr Katz there is a cure for Halitosis.

What products do I need?

The first and most important thing to do when treating Halitosis is eliminate the bulk of the Anaerobic bacteria from the mouth and throat with a good oral hygiene program incorporating products that contain no sugar, sodium lauryl sulphate or alcohol and include a toothpaste, mouthwash and tongue cle


The Therabreath essentials pack contains all of the products you need to rid yourself of Halitosis and start living with the confidence that your breath is not offensive.

Therabreath toothpaste and oral rinses contain no foaming agent, it does not mask or hide your bad breath for a few minutes behind a minty smell, it treats your Halitosis and eliminates the offensive bacteria.  The tongue cleaner is an essential part of the process to eliminate Halitosis. By removing the white/yellow layer on your tongue and exposing the bacteria that are hiding in between the hairs on your tongue, it delivers a high dosage of oxygen and creates an environment that anaerobic bacteria are unable to live in.
