What Causes Bad Breath (Halitosis)? Lasting Solutions and Treatments
Quick answer

90% of bad breath (halitosis) originates in the mouth. The most common causes are gum disease, untreated tooth decay, bacteria on the tongue, poor oral hygiene and old fillings and dentures that no longer fit well. The lasting solution is not to mask the odor but to treat its source; the first step of treatment is professional scaling.

  • Bad breath caused by the gums may require curettage and gum treatment.
  • Active cavities are restored with fillings or root canal treatment.
  • Cleaning the tongue reduces the bacterial load.
  • Brushing twice a day and flossing are recommended.
  • Drinking plenty of water helps prevent odor caused by dry mouth.

Bad breath is a condition that affects a large proportion of adults worldwide; sometimes it is merely a hygiene problem, and sometimes it is a sign of serious dental disease. It is possible to get rid of this problem, which can make you hold back in social settings, with professional treatment methods.

What Causes Bad Breath?

90% of bad breath is caused by factors originating in the mouth. The most common causes are:

  • Gum Diseases: Inflamed gums and deepened gum pockets create an ideal environment for bacteria to build up, causing odor.

  • Tooth Decay: Untreated deep cavities lead to food debris collecting and odor-producing bacteria multiplying.

  • Bacteria on the Tongue: The rough surface of the tongue is an ideal hiding place for odor-causing bacteria.

  • Poor Oral Hygiene: Not flossing and not brushing regularly are the primary causes of bad breath.

  • Old Dentures and Fillings: Food debris that seeps under fillings or crowns that have worn or no longer fit properly can cause odor.

How Is Bad Breath Treated?

The way to get rid of bad breath is not to mask the odor with sprays but to eliminate its source.

1. Professional Scaling (Tartar Removal)

Hardened tartar in areas the toothbrush cannot reach is removed with professional equipment. This is the first and most important step in treating bad breath.

2. Curettage and Gum Treatment

If the odor is caused by gum inflammation, deep cleaning of the gum pockets (curettage) may be needed. Healthy gums reduce bad breath by 80%.

3. Restoring Decayed Teeth

Active cavities causing odor are cleaned and restored with fillings or root canal treatment. Old, leaking crowns are replaced.

4. Tongue Cleaning Training

In addition to brushing, we teach our patients how to use tongue scrapers, reducing the bacterial load.
