Overview

Halitosis (bad breath) affects up to 25% of the population and is one of the most searched dental concerns in the GCC. In approximately 90% of cases the origin is inside the mouth — from bacteria on the tongue, in gum pockets, and around teeth. Temporary bad breath from food is normal. Persistent halitosis that does not resolve with brushing is a health concern requiring investigation.

Symptoms

• Persistent unpleasant odour from the mouth despite brushing
• White or yellow coating on the back of the tongue
• Dry mouth accompanying the bad breath
• Bad taste in the mouth; others commenting on breath odour

Causes & Risk Factors

• Oral causes (90%): tongue coating, periodontitis, deep gum pockets, decay, dry mouth, poorly cleaned dentures
• Tobacco and shisha use — very prevalent in Kuwait and GCC
• Dietary factors: garlic, onions, fasting, low-carbohydrate diets
• Systemic causes: GERD, sinus infection, tonsil stones, diabetes (sweet breath), kidney or liver disease

Complications

• Significant social and psychological impact: embarrassment, social withdrawal
• If caused by periodontitis: progression to tooth loss if untreated
• Underlying systemic disease may worsen without treatment

Diagnosis

Clinical examination of teeth, gums, and tongue. A halimeter may measure sulphur compound levels objectively. History identifies dietary and lifestyle factors. Referral to physician if systemic cause is suspected.

Treatment

• Professional dental cleaning and treatment of gum disease
• Tongue scraping removes bacterial coating from the back of the tongue
• Improved oral hygiene technique including interdental cleaning
• Antibacterial mouthwashes short-term; cessation of tobacco and shisha

Prevention

• Brush teeth and tongue twice daily; floss or use interdental brushes daily
• Stay hydrated; chew sugar-free gum to stimulate saliva
• Quit smoking and shisha; treat gum disease with regular cleaning
• If persistent after good oral hygiene: seek dental evaluation, not just mints
