Halitosis, commonly known as bad breath, is a health condition that affects approximately 50% of people around the world. The oral odour is normally caused by a group of anaerobic bacteria that breed beneath the surface of the tongue and sometimes in the throat and tonsils.

Underlying Causes of halitosis

There are a few factors that cause this, such as poor dental habits, which can lead to an unhygienic mouth. A dry mouth (side effect from various medications) or even consuming foods with strong odours (garlic or onions). These bacteria occur naturally in the oral environment and are essential to assist in digestion. They break down proteins that are commonly found in food, mucus or phlegm, blood, and in diseased oral tissue.

When a person fails to brush and floss their teeth sufficiently daily, food particles stay behind in your mouth. This is a catalyst for plaque and bacteria growth between teeth, gums and on the tongue causing bad breath. The same goes for overpowering foods. Onions and garlic contain pungent oils which are absorbed into the blood stream and expelled by the lungs.

According to the Academy of General Dentistry, in more than 90% of cases, the odour originates in the mouth, throat, and tonsils. Although this is something everyone experiences at one time or another. If your case does not improve after brushing, flossing, and rinsing the mouth with an alcohol-free mouthwash, it may be chronic.



Bad breath can be caused by external and internal factors. External factors are the types of foods we eat, such as spicy or odorous in nature. If you think your bad breath is related to the foods that you are consuming, consider recording the food you are eating to determine if this is the reason. People who use tobacco and alcohol can also experience bad breath.

Internal factors include oral factors that can affect the body systemically. The tongue provides a place for bacteria to attach and grow. Most odour-causing bacteria produce compounds that causes bad breath called volatile sulphur compounds (VSCs). These primary VSCs that causes bad breath are hydrogen sulphide and methyl mercaptan. Most of these odour-causing bacteria reside in the posterior area of the tongue. If you’re battling with persistent bad breath and the usual remedies aren’t helping, it might be time to consider professional assistance. Seeking bad breath treatment in Melbourne can be a game-changer, providing specialised solutions tailored to your specific needs.


1. Dry mouth

– A dry mouth provides a perfect environment for anaerobic bacteria reproduction. Long periods of speaking, smoking, drinking alcohol, and snoring are a few common causes. Most people experience bad breath in the morning due to lack of saliva production while they sleep. For healthy individuals, food odours are temporary and normal salivary flow will eliminate them within several minutes. However, those who suffer from dry mouth and lack of saliva find that even minor food odours may lead to long-term issues.

2. Food

– Halitosis can be provoked by foods such as onions and garlic because they contain smelly sulphur compounds. While dairy, meat, and fish contain dense proteins which are used as a food source by the anaerobic, sulphur-producing bacteria. Refined and processed sugars also provide a food source for bacteria. Coffee and juices can contribute to this problem because they are acidic and provide these bacteria with an ideal breeding environment.

3. Poor Dental Hygiene

– Bad oral care causes bacterial to build up on the teeth and gums. Microorganisms attach to the teeth because they cannot shed their surfaces like skin can. If they are not removed by brushing, these bacteria develop into dental plaque. When plaque is allowed to accumulate near the gum line, it will harden and begin destroying teeth and gum tissue. This leads to gum disease, which enable proteins from bleeding gums and diseased oral tissue to fuel odour-causing bacteria. Tooth decay and poorly fitting or dirty dentures can also contribute to this problem.

4. Illness and Disease

– According to studies, 10% of all halitosis cases are caused by illnesses. People that suffer from diabetes, lung disease, kidney disease, cancer, liver disease, respiratory tract infections, or metabolic disorders often experience chronic bad breath. Other common illnesses associated with bad breath include nasal odour and tonsil stones, yeast infections of the mouth, and gum disease. Drugs such as antidepressants, high blood pressure medications and antihistamines can factor into dry mouth because they reduce saliva production.


There is no quick fix to cure bad breath. Though, there is bad breath treatment in Melbourne that will help with prevention of bad breath:

1. Brush your teeth for three minutes, twice a day with combined flossing to ensure your mouth is getting a sufficient clean. This prevents plaque build-up and bacteria growth.
2. Be sure to brush your tongue, as it’s a main attraction for bacteria.
3. Gargle your mouth with a water and salt mixture or plaque reducing mouthwash to fight that oral bacteria.
4. Replace your toothbrush every three months. An old toothbrush with worn-out bristles will act as a breeding ground for bacteria and using it will only transport germs into your mouth.



In our experience, bad breath, often medically referred to as halitosis, is predominantly the result of gum disease. Addressing it might simply require scaling and tooth polishing by one of our dental hygienists. However, in some cases, it may necessitate a more involved bad breath cure. While these treatments, especially those offered as bad breath treatment in Melbourne by Collins Precision Dental, will help foster fresh breath, maintaining it is crucial. Without adopting good oral hygiene practices and ensuring regular check-ups by our practitioner or hygienist, there’s a high likelihood that bad breath will make a comeback.

5. Drink lots of water to keep your mouth moist and chew sugar-free gum. This produces more saliva which can help wash away food particles and bacteria.
6. Visit your dentist for regular dental assessments. They are trained to detect and treat periodontal disease, excessive dry mouth and other instigators of bad breath.
