Bad Breath (Halitosis)
Have you ever noticed that your breath carries a strong odor in the morning or right after eating something garlicky? It’s common for most of us to experience bad breath occasionally, but for about 2.4% of adults in Australia, chronic bad breath, also known as halitosis, can be a persistent issue that may be challenging to resolve1. Halitosis is typically caused by bacteria in the mouth that produce unpleasant odors1, but several factors can contribute to this problem. Unfortunately, it may not be immediately obvious to the person with bad breath, and it often takes someone else to point it out. For many people, bad breath can be a source of embarrassment and anxiety, and in severe cases, it can even affect relationships and overall quality of life. However, various solutions can help manage or eliminate bad breath completely.
What Causes Bad Breath?
In most cases, bad breath originates from the mouth but can also be linked to the nose, tonsils, or even underlying medical conditions3. A leading cause of bad breath is sulfur-producing bacteria that live on the tongue, in the throat1, and in the spaces between teeth.. The strength of bad breath can fluctuate during the day and may be influenced by factors such as diet, drinking habits, or smoking1. Beyond bacteria, other common causes include:
- Dry mouth, This can be caused by medications, alcohol, stress, or medical conditions.
- Tooth decay.
- Food particles trapped between teeth and starting to decay.
- Saliva flow reduction, As saliva production often decreases during sleep, resulting in “morning breath.”
- Gum disease, Conditions like gingivitis and periodontitis.
- Poor oral hygiene, Not brushing your teeth thoroughly or frequently enough.
- Smoking.
- Eating certain foods.
- Stomach acid or bile.
- Infections.
- Underlying medical conditions like kidney disease, bronchitis, or gastrointestinal issues.

Symptoms of Bad Breath (Halitosis)
Besides the bad odor you may be aware of, there are other signs of halitosis to watch out for1:
- Dry mouth.
- A white coating on the tongue, particularly at the back, which may develop from food particles, bacteria, and dead cells accumulating between the papillae (tiny bumps on the tongue). This differs from oral thrush, which may also cause a white tongue.
- Plaque buildup around teeth.
- Post-nasal drip or mucus.
- Thick saliva.
- Constant throat clearing.
- A persistent sour, bitter, or metallic taste.
Living with bad breath can be uncomfortable and significantly affect self-esteem and confidence.
How to Get Rid of Bad Breath

- Good oral hygiene, Brush and floss thoroughly every day.
- Stay hydrated, Drink plenty of water to avoid dry mouth.

When to See a Doctor
If your bad breath persists despite maintaining good hygiene or is negatively affecting your self-esteem, it’s best to consult with a GP or dentist. They can help rule out any underlying causes and recommend the best treatment options. If your bad breath stems from a medical condition, your GP will guide you on the next steps.
