At WeSmile Dental, we often get asked one very personal — and sometimes embarrassing — question: how to get rid of bad breath. It’s more common than many think, and trust us — you’re not alone. Whether it’s a strong odour in the morning, a persistent issue after meals, or something that just won’t go away no matter how much you brush, bad breath can affect confidence, communication, and even your social life.
In this guide, we’ll help you understand what causes bad breath, discuss the types of bad breath smells, explore effective options like mouthwash, and even answer questions about using remedies such as apple cider vinegar for bad breath from stomach. Most importantly, we’ll offer realistic, dentist-approved strategies on how to get rid of bad breath — in ways that are safe, manageable, and suited to your lifestyle.
What Causes Bad Breath?
Understanding what causes bad breath is the first step to tackling it properly. The medical term for bad breath is halitosis, and while it’s often harmless, it can sometimes indicate a deeper oral or health-related issue.
Here are the most common causes:
- Poor oral hygiene: Not brushing or flossing well allows food particles to stay in your mouth, breaking down and creating odours.
- Bacteria on the tongue: Your tongue is a hotspot for bacterial build-up.
- Dry mouth: Saliva helps cleanse your mouth. When your mouth is dry — due to medication, dehydration, or mouth-breathing — odours can linger.
- Diet: Foods like garlic, onions, and spicy dishes are obvious culprits. But lesser-known ones include dairy and high-protein diets.
- Gum disease: Persistent bad breath may be a symptom of gum infection.
- Medical issues: In some cases, bad breath could be linked to sinus problems, acid reflux, or conditions like diabetes.
When you visit WeSmile Dental, we take time to investigate the root of the issue — because knowing what causes bad breath makes a real difference in finding the right solution for you.
Types of Bad Breath Smells and What They Could Mean
Believe it or not, the types of bad breath smells can sometimes give clues about their origin. While this is not a diagnostic method, it can be helpful in a dental consultation.
Here’s what different smells might indicate:
- Rotten or sulphuric: Often caused by bacteria breaking down food in the mouth or between teeth.
- Fruity: In people with diabetes, this could be a sign of ketoacidosis.
- Acidic or sour: May point to stomach acid or reflux-related issues.
- Fecal or decaying smell: Could be linked to advanced gum disease or poor dental hygiene.
If you notice any persistent or unusual smells, it’s important to speak to your dentist. At WeSmile Dental, we don’t just mask odours — we help uncover their root cause to give you the best guidance on how to get rid of bad breath safely and effectively.

Mouthwash to Get Rid of Bad Breath: Does It Work?
Many people reach for mouthwash to get rid of bad breath, and it can indeed be part of a good oral hygiene routine — but not all mouthwashes are created equal.
Here’s what you need to know:
Cosmetic mouthwashes for bad breath
Cosmetic mouthwashes are designed to temporarily improve the freshness of your breath. They often contain flavouring agents such as mint or other aromatic oils that help mask unpleasant odours. However, they do not target the underlying causes of bad breath, such as plaque build-up, dry mouth, or bacterial growth. These products may be useful for a quick refresh but are not intended for long-term oral hygiene management.
Therapeutic mouthwashes for bad breath
Therapeutic mouthwashes may contain active ingredients such as chlorhexidine, cetylpyridinium chloride, or essential oils that can help reduce oral bacteria and control plaque. These formulations are designed to support daily oral hygiene by helping to neutralise odour-causing compounds. They are typically recommended for short-term use and should be used according to the label directions or as advised by a dental professional.
Alcohol-free mouthwash options
Alcohol-free mouthwashes are gentler on the oral tissues and are often preferred by individuals with sensitive mouths or those who experience dryness. They do not cause the burning sensation that can be associated with alcohol-based rinses and are generally suitable for regular daily use. These options may help maintain a balanced oral environment and support fresh breath without contributing to further dryness.
While mouthwash can be useful, it should never replace brushing and flossing. We also recommend checking with your dentist before using strong or medicated products regularly. At WeSmile Dental, we’re happy to recommend a mouthwash that suits your oral health and addresses how to get rid of bad breath in a long-term, sustainable way.
Apple Cider Vinegar for Bad Breath from Stomach: Fact or Fiction?
There’s been a growing interest in using apple cider vinegar for bad breath from stomach. The idea is that it may help with digestion and acid balance, potentially reducing odours caused by reflux or gut issues.
Here’s what we can tell you:
- There’s no strong scientific evidence supporting apple cider vinegar as a reliable way to eliminate bad breath.
- For some, small amounts diluted in water before meals may help stimulate digestion — but it’s not a guaranteed fix.
- Overuse can damage tooth enamel or worsen acid reflux for some individuals.
If you suspect your bad breath is coming from your stomach rather than your mouth, it’s best to speak to both a dentist and a medical doctor. At WeSmile Dental, we’ll help rule out oral causes first before referring you for further medical review if needed.
Best Practices on How to Get Rid of Bad Breath (From a Dentist’s Perspective)
If you’re serious about learning how to get rid of bad breath, here’s what we usually recommend — tailored to your individual needs:
Get rid of bad breath by Brushing and flossing regularly
Brush at least twice a day, and floss once daily. Pay extra attention to the gum line and hard-to-reach areas.
Get rid of bad breath by Cleaning & scraping your tongue
Use a tongue scraper or your toothbrush to gently clean the surface of your tongue. This simple step can reduce odour-causing bacteria dramatically.
Get rid of bad breath by Staying hydrated
Drink water throughout the day. A dry mouth is more likely to harbour bacteria and odour.
Visit your dentist regularly to avoid bad breath
A dental check-up helps identify and treat underlying causes like gum disease, plaque, or decay that could be contributing to bad breath.
Use dentist-recommended mouthwash to get rid of bad breath
As discussed earlier, the right mouthwash to get rid of bad breath should be part of your oral care routine — not the whole solution.
Get rid of bad breath through adjusting your diet
Reduce foods that are known to cause odours. Sugar and acidic beverages can also contribute to bacterial growth.
Get rid of bad breath by Addressing underlying medical issues
If dental causes are ruled out, you may need to investigate gastrointestinal issues, allergies, or nasal infections that could contribute to odour.
At WeSmile Dental, we customise your care — because the journey to fresher breath is different for everyone.
Why Getting Rid of Bad Breath Matters
