When to consult a doctor for bad breath?

If bad breath persists despite good oral hygiene

If your bad breath doesn’t improve even after brushing, flossing, and using mouthwash, it could signal other infections or diseases. See a doctor for persistent bad breath and identify the root cause.

If bad breath is accompanied by other symptoms

If you experience metallic taste, dry mouth, mouth sores or difficulty swallowing, it could point to certain underlying conditions such as diabetes, kidney stones or throat infections. Seek medical opinion from a doctor in this case.

If there are signs of infection or disease

Bad breath caused by swollen gums, bleeding, or cavities should not be ignored. These may indicate gum disease or tooth decay, which can worsen if left untreated. Get medical advice from a doctor to prevent further complications.

Causes of bad breath

Poor oral hygiene, such as not brushing well or flossing

Strong-smelling foods like garlic, onions, and spices

A lack of saliva, due to dehydration, medications, or a certain condition
Gum infections can result in foul-smelling breath due to bacteria in the gums.

Tobacco products dry out the mouth and leave a persistent odour, while also increasing the risk of gum disease.

Respiratory infections (like sinusitis or bronchitis), tonsillitis, or mouth infections like abscesses can produce foul odours.

Acid reflux or ulcers

Diabetes, kidney disease, or liver disease can cause distinctive odours in the breath.

Treatment and prevention

Depending on the underlying cause, bad breath can be cured permanently. 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. Some prevention steps, after a GP consultation, can include:

Brush your teeth at least twice a day, floss daily, brush your tongue and use an antibacterial mouthwash.

Drink plenty of water throughout the day to prevent dry mouth.

Chewing gum can stimulate saliva production, helping to keep your mouth moist and fresh.

Limit foods like garlic, onions, and strong spices, which can temporarily affect your breath.

Smoking and tobacco use contribute to bad breath and dry mouth. Quitting smoking can significantly improve your breath and overall oral health.

Routine dental checkups help identify and treat underlying issues like gum disease, cavities, or infections that can cause bad breath.

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.

Rinse your mouth with a mix of water and baking soda or a diluted solution of apple cider vinegar to neutralise odours.
