About bad breath

Medically reviewed by Dr. Ammar AL-ANI, MBChB, CCBST, AMC
When to consult a doctor for bad breath?
Bad breath, or halitosis, can be caused by a variety of factors. While occasional bad breath is common, especially after eating certain foods, it can sometimes be a sign of an underlying health issue. You should consider consulting a doctor if:
- Persistent bad breath: If bad breath persists even after maintaining good oral hygiene, it might indicate a health condition like gum disease, sinus infections, or digestive issues.
- Accompanied by other symptoms: If you experience other symptoms along with bad breath, such as a dry mouth, mouth sores, or changes in taste, it could point to an underlying medical issue that needs attention.
- Sign of infection or disease: Bad breath that smells like ammonia or is accompanied by a metallic taste could suggest kidney problems. A fruity odour may indicate uncontrolled diabetes, while a foul smell might be linked to respiratory or gastrointestinal issues.
- Gum disease or cavities: If you have visible signs of gum disease (swollen, bleeding gums) or cavities, it’s important to see a dentist or doctor to prevent further complications.
- Difficulty breathing or swallowing: If bad breath is associated with trouble breathing or swallowing, it could be a sign of a more serious condition like a throat or lung infection.
What causes bad breath?
Bad breath, or halitosis, can be caused by a variety of factors. Here are the most common causes:
- Poor oral hygiene: Inadequate brushing and flossing can lead to food particles remaining in the mouth, promoting bacterial growth and causing bad breath.
- Food choices: Strong-smelling foods like garlic, onions, and spices can temporarily affect your breath.
- Dry mouth: Saliva helps cleanse the mouth. A lack of saliva, due to dehydration, medications, or conditions like Sjögren’s syndrome, can lead to dry mouth, causing bad breath.
- Gum disease: Gum infections, such as gingivitis or periodontitis, can result in foul-smelling breath due to bacteria in the gums.
- Smoking: Tobacco products dry out the mouth and leave a persistent odour, while also increasing the risk of gum disease.
- Infections or illnesses: Respiratory infections (like sinusitis or bronchitis), tonsillitis, or mouth infections like abscesses can produce foul odours.
- Gastrointestinal issues: Conditions like acid reflux or ulcers may cause bad breath due to the regurgitation of stomach acids or gases.
- Underlying medical conditions: Conditions like diabetes, kidney disease, or liver disease can cause distinctive odours in the breath.
What diseases cause bad breath?
Several diseases and health conditions can contribute to bad breath (halitosis). Some of the most common ones include:
- Gum disease: Infections in the gums, like gingivitis or periodontitis.
- Diabetes: Uncontrolled diabetes, especially when blood sugar levels are high.
- Sinus infections (Sinusitis): Chronic sinus infections or post-nasal drip can lead to bad breath.
- Respiratory infections: Conditions like bronchitis, pneumonia, or a cold can cause bad breath.
- Gastro-Oesophageal Reflux Disease (GORD): Acid reflux or GORD can cause stomach acids to move into the mouth, leading to bad breath and a sour taste.
- Liver disease: Liver conditions, such as cirrhosis, can cause a musty or foul odour in the breath.
- Kidney disease: Kidney failure can cause ammonia-like bad breath due to the accumulation of urea in the body.
- Tonsillitis: Inflammation or infection of the tonsils.
- Stomach ulcers: Digestive issues like stomach ulcers can cause bad breath.
- Sjögren’s syndrome: This autoimmune disorder causes dry mouth, which reduces saliva flow and promotes bacterial growth, leading to bad breath.
How to get rid of bad breath?
To get rid of bad breath, you can follow these steps to address the common causes and improve oral and overall health:
- Practise good oral hygiene: Brush your teeth at least twice a day, floss daily, brush your tongue and use an antibacterial mouthwash to reduce bacteria in the mouth and freshen breath.
- Stay hydrated: Drink plenty of water throughout the day to prevent dry mouth, which can lead to bad breath.
- Chew sugar-free gum: Chewing gum can stimulate saliva production, helping to keep your mouth moist and fresh.
- Avoid foods that cause bad breath: Limit foods like garlic, onions, and strong spices, which can temporarily affect your breath.
- Quit smoking: Smoking and tobacco use contribute to bad breath and dry mouth. Quitting smoking can significantly improve your breath and overall oral health.
- Get dental checkup regularly: Routine dental checkups help identify and treat underlying issues like gum disease, cavities, or infections that can cause bad breath.
- Treat underlying health conditions: If your bad breath is caused by an underlying condition such as GORD, diabetes, or sinus infections, addressing and managing the condition can help improve your breath.
- Use natural remedies: Rinse your mouth with a mix of water and baking soda or a diluted solution of apple cider vinegar to neutralise odours. Chew on fresh herbs like parsley, mint, or fennel, which can help freshen breath naturally.
Can you cure bad breath permanently?
Curing bad breath permanently depends on the cause. If it’s due to oral hygiene or temporary factors like food or dry mouth, it can be controlled. However, if bad breath is linked to a medical condition, such as gum disease or diabetes, ongoing treatment of the underlying issue is necessary.
