5 Common Causes of Bad Breath (and what to do about it)

June 12, 2024 5 Common Causes of Bad Breath (and what to do about it)

Struggling with bad breath? If so, you are not alone. Every local dentist knows this is a common issue people face. Bad breath (or “halitosis”) is a common problem that affects millions of people around the world. Fortunately, there are several potential causes of bad breath and specific solutions for each one. In this article, we explore the five most common causes of bad breath and how to eliminate them for good!

  1. Poor Oral Hygiene: Poor oral hygiene is one of the most common causes of bad breath. This includes not brushing or flossing regularly, failing to scrape your tongue with a tongue scraper, and not using mouthwash regularly. To eliminate bad breath caused by poor oral hygiene, be sure to brush and floss twice daily, scrape your tongue once a day, and use an alcohol-free mouthwash at least once a day.

  2. Dry Mouth: Saliva is essential for keeping bacteria levels in your mouth low; when saliva production decreases due to dehydration or certain medications, this can cause an increase in bad breath. To overcome dry mouth, make sure you are properly hydrated throughout the day and consider using an artificial saliva product if needed.
  3. Food: Some foods, such as garlic and onions, can cause bad breath due to their strong scents. To eliminate bad breath caused by food, brush your teeth or chew sugar-free gum after eating these smelly foods. Additionally, avoid smoking cigarettes and consuming alcohol as these two habits can contribute to bad breath.
  4. Sinus Issues: Nasal and sinus issues can cause a buildup of mucus in the back of your throat, which can lead to bad breath. To eliminate bad breath caused by sinus issues, use saline nasal sprays or steam treatments to flush out the excess mucus and keep your nose and sinuses clear.
  5. Medical Conditions: Bad breath can also be a sign of underlying medical conditions, such as diabetes or kidney and liver diseases. If you have persistent bad breath that won’t go away despite brushing and flossing regularly, visit your doctor to rule out any serious health issues.


By following these tips, you can eliminate bad breath for good and enjoy fresh-smelling breath all day long! Don’t believe us? See what our patients have said about us!
