Bad Breath (Halitosis)

What Causes Bad Breath?

Occasional bad breath happens to everyone, but chronic bad breath (halitosis) that doesn't go away with brushing and mouthwash can be embarrassing and may indicate an underlying dental or health issue. The good news is that most causes of bad breath are treatable.

Common Causes

• Poor oral hygiene allowing bacteria to build up
• Gum disease (a leading cause of persistent bad breath)
• Food particles trapped between teeth
• Dry mouth (reduced saliva production)
• Smoking or tobacco use
• Certain foods like garlic and onions
• Dental infections, cavities, or abscesses
• Tongue coating of bacteria

When to See a Dentist

If bad breath persists despite good oral hygiene, or if it's accompanied by bleeding gums, toothache, dry mouth, or a bad taste, see a dentist. Chronic halitosis is often a sign of gum disease or decay that needs treatment.

Getting Fresh Breath Back

We'll identify the root cause through a thorough examination. Treatment may include professional cleaning to remove tartar, treating gum disease, filling cavities, or recommending specific oral care products. Sometimes bad breath originates from the tongue — we can show you proper tongue cleaning techniques.

Quick Fixes and Long-Term Solutions

For immediate freshness, sugar-free gum and mints can mask bad breath temporarily, but they do not address the underlying cause. Effective long-term solutions start with a thorough oral hygiene routine: brush twice daily for at least two minutes, floss once daily to remove food particles between teeth, and clean your tongue with a tongue scraper or the back of your toothbrush — the tongue harbours the majority of odour-causing bacteria. Stay hydrated throughout the day, as saliva naturally washes away bacteria and food debris. An antibacterial mouthwash can help reduce bacterial levels, but avoid alcohol-based rinses that dry out your mouth and actually worsen bad breath over time. If you wear dentures, clean them thoroughly every night. Scheduling regular professional cleanings every six months removes hardened tartar that you cannot remove at home and is one of the most effective ways to maintain fresh breath.

Bad Breath and Systemic Health

Persistent bad breath can sometimes indicate health issues beyond your mouth. While the majority of halitosis cases originate from oral bacteria, gum disease, or tooth decay, certain systemic conditions can also cause chronic bad breath. Gastroesophageal reflux disease (GERD) allows stomach acids to travel upward, producing an unpleasant odour. Uncontrolled diabetes can create a fruity or acetone-like smell on the breath. Chronic sinus infections and postnasal drip provide a breeding ground for bacteria. Liver and kidney conditions can also produce distinct breath odours as the body struggles to filter toxins. If your dentist at Redwater Dental Clinic rules out oral causes of your bad breath, we may recommend consulting your physician for further evaluation. Addressing bad breath comprehensively protects both your confidence and your health. Call 780-942-4691 to schedule a consultation.
