Halitosis Overview

Halitosis, or chronic bad breath, goes beyond the usual morning breath or a garlicky lunch. It is a persistent condition, often a symptom of an underlying oral or health issue.

Primary Causes

  • Poor Oral Hygiene: Not brushing or flossing regularly can leave food particles in the mouth, leading to bacteria growth and bad breath. This also applies to improperly cleaned dentures.
  • Gum Disease: Persistent bad breath might indicate progressing periodontal disease, caused by bacterial buildup.
  • Tobacco and Alcohol Use: These substances leave lingering chemicals in the mouth and bloodstream, contributing to bad breath.
  • Dry Mouth: A lack of saliva, as seen in conditions like xerostomia, hinders mouth cleansing and can cause bad breath.
  • Strong-Smelling Foods: Garlic and onions, among other foods, are known to cause temporary bad breath.
  • Underlying Health Issues: Medical conditions such as diabetes, liver disease, and chronic reflux can also lead to halitosis.

How Mouthwash Fights Halitosis

Mouthwash is an effective tool in combating halitosis, providing a two-pronged approach: it directly kills the bacteria causing the odor and masks the foul smell with a refreshing scent.


  • Kills Bacteria: Most mouthwashes have antiseptic components like alcohol, chlorhexidine, cetylpyridinium chloride, or essential oils. They help kill the bacteria responsible for bad breath.
  • Neutralizes Odor: Mouthwash often contains ingredients like eucalyptol, menthol, or thymol, which provide a fresh scent and a cooling sensation, effectively neutralizing bad breath.

Important Factors to Consider

When selecting a mouthwash to combat halitosis, there are a few key factors to keep in mind.

Key Factors

  • Alcohol Content: If you have a sensitive mouth or dry mouth issues, consider an alcohol-free mouthwash.
  • Active Ingredients: Look for antiseptics like cetylpyridinium chloride or chlorhexidine, and ingredients like zinc or chlorophyll for bad breath control.
  • Fluoride: For cavity or gum disease prevention, choose a fluoride-containing mouthwash.
  • Taste Preference: Since it’s a daily use product, select a flavor you enjoy.
  • Price Range: Mouthwash prices vary, so set a budget beforehand.
  • Brand and Reviews: Opt for a reputable brand and check reviews to see if it suits your needs.

Best Mouthwash for Halitosis

Leveraging my extensive knowledge and experience in dental health, I’ve navigated through many products on the market and handpicked the top 5 types of mouthwash explicitly designed to counteract halitosis.

1. Best Overall | TheraBreath Fresh Breath

Best Gum Care

Since 1994 they’ve been creating oral care products that treat halitosis, gum disease, tooth decay, stained teeth, immune support, tooth sensitivity, and dry mouth. The original TheraBreath formulation attacks odor-causing bacteria rather than masking it with heavy flavors or powerful odors.

TheraBreath is one of the five largest oral care companies and the largest privately-held manufacturer. TheraBreath Oral Rinse stimulates saliva flow and circulates antibacterial, oxygen-rich bacteria throughout your mouth.
