What Your Chronic Bad Breath May Be Telling You
Chronic bad breath, or halitosis, can be more than just embarrassing; it can be a sign of an underlying health issue. Read on to learn what might be causing your chronic bad breath and how we can help you find a solution.

While it's normal to have bad breath occasionally, persistent bad breath can be a sign of something more than just the garlic bread you had for lunch. As an experienced general and cosmetic dentist, Thomas Eaton, DDS, in Ione, California, can diagnose the cause of your chronic bad breath and find a solution.

The most common causes of bad breath

Most bad breath starts in the mouth. The most common culprits are bacteria that live on your tongue and in your throat. These bacteria break down proteins and release odorous compounds. Poor oral hygiene is a primary cause, as it allows food particles to remain in your mouth, leading to the formation of plaque. Other common causes include:

  • Dry mouth (xerostomia): Saliva helps clean your mouth; a lack of it causes bad breath.
  • Gum disease: Persistent bad breath is a common sign of gingivitis and periodontitis.
  • Food and drink: Certain contributors to bad breath include onions, garlic, alcohol, and coffee.
  • Tobacco use: Smoking and other tobacco products cause bad breath and gum disease.

When bad breath is a sign of something more

Chronic bad breath can be a symptom of an underlying medical condition. If you have good oral hygiene habits but still experience bad breath, it's essential to consider other potential causes. Some medical conditions that can cause bad breath include:

  • Respiratory tract infections: Infections in your nose, sinuses, or throat can lead to postnasal drip, which can cause bad breath.
  • Tonsil stones: These small, bacteria-covered stones can form in your tonsils and produce a strong odor.
  • Acid reflux (GERD): The regurgitation of stomach acid can cause a sour taste and bad breath.
  • Systemic diseases: Certain diseases, such as diabetes, liver disease, and kidney disease, can cause bad breath due to the chemical changes they produce in your body.

How can we help

If you're concerned about chronic bad breath, the first step is to schedule a dental exam. Dr. Eaton can help determine the cause of your bad breath by examining your teeth and gums, as well as discussing your medical history. Depending on the cause, he may recommend:
