Symptoms & conditions

Bad breath

Routine — book when convenient

The short answer

Persistent bad breath (halitosis) usually comes from one of four places: tongue coating (60% of cases), gum disease pockets, dry mouth, or non-oral issues like sinusitis or GERD. Mouthwash masks for 20 minutes; a proper diagnosis actually fixes it.

What's happening

The clinical picture

Volatile sulphur compounds produced by anaerobic bacteria are what you smell. Those bacteria live in three main places: the back third of the tongue (where most people never clean), periodontal pockets deeper than 4 mm, and any low-saliva environment. Sinusitis and post-nasal drip produce odour that exits through the mouth but originates above it. If your dentist examines you and finds clean teeth, healthy gums, a clean tongue, and normal saliva, the cause is not dental — time to see an ENT or GP.

Warning signs

Contact us the same day if:

  • Bad breath that doesn't improve with brushing and tongue scraping
  • Persistent bad taste
  • White coating on the tongue that won't brush off
  • Dry mouth throughout the day
  • Bleeding gums accompanying the smell

What we do

Our approach

Exam includes tongue inspection, periodontal probing, and saliva-flow check. Based on what we find: tongue-scraping coaching, deep gum cleaning, dry-mouth management, or a referral out to ENT/gastroenterology if the cause is elsewhere. No "magic mouthwash" sales.
