What to Do About Bad Breath (Halitosis)
06/07/2026
Bad breath, also known as halitosis, is a common problem that affects many people at some point in their lives. It can be embarrassing and may affect your confidence, but the good news is that there are usually simple steps you can take to improve it.
What Causes Bad Breath?
In most cases, bad breath starts in the mouth. Bacteria naturally live on the teeth, gums, and tongue. As these bacteria break down food particles, they release unpleasant-smelling gases.
Common causes of bad breath include:
- Poor oral hygiene
- A build-up of plaque and bacteria
- Gum disease
- Food trapped between teeth
- A coated tongue
- Dry mouth
- Smoking and tobacco use
- Certain foods such as garlic, onions, and spicy dishes
Sometimes, persistent bad breath can be linked to medical conditions such as sinus infections, acid reflux, diabetes, or other health issues.
How Can You Improve Bad Breath?
Brush Thoroughly Twice a Day – Brush your teeth for two minutes, twice daily, using fluoride toothpaste. Make sure you clean all tooth surfaces, especially along the gumline where plaque can build up.
Clean Between Your Teeth – Food and bacteria often collect in places your toothbrush cannot reach. Daily flossing or using interdental brushes can help remove trapped debris and reduce odour-causing bacteria.
Don’t Forget Your Tongue – The tongue can harbour large numbers of bacteria. Gently cleaning your tongue with a tongue scraper or your toothbrush can make a significant difference to breath freshness.
Stay Hydrated – A dry mouth encourages bacterial growth and can make bad breath worse. Drinking plenty of water throughout the day helps keep your mouth moist and naturally cleanses away bacteria.
Use an Antibacterial Mouthwash – A mouthwash can help reduce bacteria and temporarily freshen breath. However, it should be used alongside brushing and flossing, not as a replacement.
Avoid Smoking – Smoking contributes to bad breath, stains teeth, and increases the risk of gum disease. Stopping smoking can improve both your oral health and breath.
Watch What You Eat – Strong-smelling foods can affect your breath for several hours after eating. Maintaining a balanced diet and limiting sugary snacks can also help reduce bacterial growth.
When Should You See a Dentist?
If your bad breath continues despite good oral hygiene, it is worth booking a dental check-up. Persistent halitosis can sometimes be a sign of:
- Gum disease
- Tooth decay
- Dental infections
- Poorly fitting dental appliances
- Dry mouth conditions
Your dentist can identify the cause and recommend the most effective treatment.
The Bottom Line
Bad breath is a common and often treatable problem. Regular brushing, cleaning between your teeth, tongue cleaning, and staying hydrated can make a big difference. If the problem persists, a dental examination can help uncover any underlying issues and get your oral health back on track.
