Bad breath is more common than most people think, and it can be a source of frustration. The good news is that the underlying causes are usually treatable. Understanding what is behind it is the first step toward managing it effectively.

At our Point Cook dental clinic, we regularly help patients who are concerned about bad breath. Contact us to book an appointment and our team can assess the cause and recommend the right approach.

Bad Breath Explained

Bad breath, known clinically as halitosis, is an unpleasant odour in the air you breathe out. It can originate both inside and outside the mouth, but most commonly occurs when bacteria in the mouth produce sulphur-smelling gases.

There are over 500 species of bacteria that live in the mouth, and many of them can produce an odour. These bacteria tend to thrive when oral health issues are present, such as insufficient hygiene, dry mouth, gum disease, or infection.

For some people, bad breath is occasional. For others, it is persistent. The frequency often depends on the cause, which is why a dental check-up is a good starting point.

Common Causes of Bad Breath

Beyond the bacteria that live on the tongue and throat, other causes include:

• Dental factors: plaque and tartar buildup, periodontitis (infection around the teeth), gum disease, cracked fillings or crowns, unclean dentures, or decay
• Dry mouth: can be caused by medications, alcohol, stress, or a medical condition
• Smoking: reduces oxygen in the mouth
• Certain foods: items such as onions, garlic, or spicy foods can cause short-term odour

In some cases, bad breath may be caused by dieting, systemic illness, or other conditions in the body. If we cannot identify a dental cause, we may recommend a visit to your doctor. Less common causes include acid or bile reflux, kidney issues, or post-nasal discharge from chronic sinusitis.

Treatment Options

At The Point Dental, treatment depends on the underlying cause. If the issue is dental, common treatments include:

• White fillings
• Gum treatment
• Root canal treatment
• Wisdom teeth removal

If gum disease is present, the gums may have receded from the teeth, creating space where odour-causing bacteria can accumulate. Professional cleaning may be needed to remove this buildup. Decayed teeth and faulty restorations can also harbour bacteria, so accurate diagnosis of the source is important for effective treatment.

Oral Care Tips

Good daily habits can make a significant difference in managing bad breath. We recommend:

• Brushing twice a day and flossing once a day
• Staying well hydrated throughout the day
• Using a suitable mouthwash or toothpaste as recommended by your dentist
• Visiting your dentist twice a year for a check-up and clean

Other factors to be aware of:

• Avoid smoking or chewing tobacco
• Minimise alcohol intake
• Check whether any medications you are taking may contribute to dry mouth

With consistent oral care and guidance from your dentist, the underlying causes of bad breath can usually be identified and managed effectively.
