Chronic Bad Breath: Causes and How to Fix It

Everyone has bad breath now and then, but when it becomes a persistent problem, it can affect your confidence and may signal an underlying issue. The good news is that chronic bad breath, or halitosis, almost always has an identifiable cause and a solution. Here is what you need to know.

The most common cause

The majority of bad breath starts in the mouth, from bacteria that break down food particles and release unpleasant odors. These bacteria thrive on the tongue and between the teeth, especially when brushing and flossing are inconsistent. Often, improving oral hygiene solves the problem.

Other causes to consider

  • Dry mouth: less saliva means less natural cleansing, which worsens odor
  • Gum disease: a common and important cause of persistent bad breath
  • Certain foods: garlic, onions, and others cause temporary odor
  • Tobacco: both causes odor and dries the mouth
  • Other health conditions: occasionally, bad breath points to an issue elsewhere

How to fix it

Start with the basics: brush twice a day, floss daily, and gently clean your tongue, where much odor originates. Staying hydrated keeps saliva flowing, and sugar-free gum can help in a pinch. Regular cleanings remove the buildup that fuels odor.

When to see a dentist

If bad breath persists despite good habits, it is worth a dental visit. Your dentist can check for gum disease, dry mouth, or other dental causes, and help you get to the bottom of it rather than just masking it with mints or mouthwash.

Frequently Asked Questions
