Bad Breath That Won’t Go Away? Here’s What Might Be Behind It

We’ve all had bad breath after a strong coffee or a garlicky meal, but if it’s happening all the time — even after brushing — it could be a sign of something more serious. Persistent bad breath, also called halitosis, can be caused by a range of dental and health issues. The good news? In most cases, the cause can be found and treated.

In this article, we’ll look at common reasons for ongoing bad breath, how to fix it, and when it’s time to see a dentist.

What Causes Occasional Bad Breath?

• Strong-smelling foods – Garlic, onions, and spicy dishes can linger for hours.

• Morning breath – Saliva production slows during sleep, allowing bacteria to grow.

• Coffee and alcohol – Both dry out the mouth, leading to odour.

When It’s More Than Just Food

If bad breath doesn’t improve after brushing, flossing, and rinsing, it might be due to bacteria or an underlying condition rather than just diet.

Dental Causes of Persistent Bad Breath

• Gum disease – Bacteria in infected gums release a strong odour.

• Tooth decay – Cavities can trap food and bacteria.

• Tongue coating – Bacteria can build up on the tongue’s surface.

• Old dental work – Worn fillings or ill-fitting crowns can harbour bacteria.

Other Health-Related Causes

• Dry mouth – Reduced saliva means less natural cleansing.

• Sinus or throat infections – Mucus can contribute to bad breath.

• Digestive issues – Reflux or stomach problems can produce odours.

• Certain medications – Some reduce saliva flow or have odorous side effects.

How to Freshen Your Breath Daily

• Brush twice a day with fluoride toothpaste

• Clean between teeth with floss or interdental brushes

• Brush your tongue or use a tongue scraper

• Drink plenty of water

• Avoid smoking and excessive alcohol

• Use sugar-free gum to stimulate saliva
