Bad Breath: Let’s be honest. Bad breath happens to all of us, especially after eating a garlicky dish or upon waking in the morning. But when it doesn’t go away, it might be more than just skipped brushing; it could be a sign of something more serious.
Bad breath, also known as halitosis, can be a red flag when it doesn’t improve with brushing, flossing, or mouthwash. So, when should you be concerned?

Causes of bad breath:
Poor oral hygiene: Poor oral hygiene is one of the leading causes, with plaque build-up and food particles that remain in your mouth, teeth and gums.
Certain food items like garlic, onions and specific spices can stay in the breath for hours. This often leads to bacterial growth and odour. Sometimes, the food particles trapped between teeth can also trigger bad breath.
Dry mouth (xerostomia): A dry mouth reduces saliva’s natural cleansing action. This allows the odour-causing bacteria to thrive and create an unpleasant smell.
Gum disease (gingivitis or periodontitis): Gums having inflammation or infected gums can cause bad breath.
Smoking: Smoking regularly can cause gum disease and dry mouth, both leading to bad odour.
Cavities and infected teeth: Tooth decay and dental infections often lead to foul-smelling breath, as bacteria build up in decayed or infected areas.
What are the signs that bad breath could be something serious?
Constant bad breath despite good oral hygiene indicates systemic diseases. Here are some serious conditions that could cause chronic halitosis:
Sinus: Sinusitis, post-nasal drip, and tonsillitis can produce foul-smelling mucus that contributes to bad breath.

Diabetes: Poorly managed diabetes can lead to a sweet, fruity breath smell caused by a buildup of ketones in the body.
Liver or kidney disease: Serious liver or kidney issues can cause bad breath. A fishy smell might mean kidney trouble, and a sweet or musty odour could be a sign of liver problems.
Gastroesophageal Reflux Disease (GERD): Acid reflux or GERD can cause stomach acids to rise into the mouth, resulting in sour-smelling breath and gradually wearing down tooth enamel.

When to seek medical help?
If you experience sudden severe bad breath or breath odour which is accompanied by other symptoms such as unexplained weight loss, constant coughing, changes in urination and chronic fatigue, such patterns deserve medical attention.
If bad breath lasts longer than a few days and doesn’t improve with better oral care, it’s advised to seek professional help from a dentist or physician. Regular dental checkups and cleanups are good preventive measures for bad breath.
