Bad breath, or halitosis, is that humiliating and odious affliction—particularly on cozy talks, business meetings, or blind dates. While garlic and spicy meals are usually suspected to be the main culprits, it turns out that 80–90% of bad breath are due to poor oral hygiene and bacterial overgrowth in the mouth, not what you have eaten.

Whether you want to increase your confidence or enhance your oral hygiene, knowing the cause of bad breath is the key to fresh breath and enhanced social relationships.

What Is Halitosis and Who Is Affected?

Halitosis afflicts nearly 30% of the planet's population, in all age ranges—even children. Social and psychological effects can be drastic, having the tendency to decrease self-esteem and introduce additional stress to social or work interactions than is required.

As Nicola West, Secretary General of the European Federation of Periodontology (EFP), tells us, bad breath may also be an indicator of more serious oral conditions such as gingivitis or periodontal disease. Such conditions are usually not noticeable until they begin causing symptoms such as chronic bad breath or bleeding gums.

The mouth is the perfect environment for bacteria: it's warm, damp, and often brimming with food particles. As bacteria ferment leftover organic material—particularly proteins—they release volatile sulfur compounds (VSCs) which emit a pungent smell.

Tali Chackartchi, EFP President-elect and organizer of Gum Health Day 2025, explains that more than 85% of halitosis cases are caused by oral reasons such as:

• Tongue coating
• Poor brushing technique
• Infrequent flossing
• Gingivitis and plaque

"If there is gum disease, then there are further 'niches' in which the bacteria can reside and make the breath smell more unpleasant," explains West. Bleeding gums and halitosis are typically a sign of an infection that will need to be treated professionally.

How to Treat and Prevent Bad Breath

Bad breath treatment is about eradicating the bacteria at its source. Here are some tips endorsed by experts for fresher breath:

1. Improve Your Daily Oral Hygiene Routine

• Brush your teeth twice daily with a soft-bristle toothbrush
• Don't forget to clean your tongue, where bacteria are likely to accumulate
• Floss daily or use interdental brushes
• Rinse with an antibacterial mouthwash

2. Stay Hydrated

Drink plenty of water during the course of the day. A dry mouth lacks enough saliva, which removes food bits and acids.

3. Stop Smoking

Smoking dries out the mouth and introduces toxins into the mouth that irritate bad breath and damage gum tissue.

4. Seek Professional Assistance

Chackartchi recommends seeing a periodontist for a complete diagnosis and personally tailored treatment plan. "Every 3–6 months, professional cleanings can prevent inflammation and halitosis from recurring," she recommends.

Final Thoughts: A Breath of Fresh Air

Bad breath is not something you must learn to live with. Most cases can be resolved with better oral hygiene, regular, professional care, and good lifestyle choices. By addressing the root causes, you are able to revive not only fresh breath but also confidence.
