Bad Breath and Halitosis

Halitosis is a persistent, unpleasant odour in exhaled breath. It is a chronic condition caused by tooth decay, debris on the tongue, and dehydration of mouth, nose and throat infections. Bad breath is temporary and is often caused by inadequate brushing, morning breath or food debris left on teeth

Dental cleaning may be the solution if plaque accumulation is the cause of bad breath. A deep dental cleaning may be necessary if you have periodontal disease.

Treating underlying medical problems, such as a sinus infection or kidney disease, can also help improve breath odour. If dry mouth is the cause of your bad odour, your dentist may advise using products that stimulate the secretion of saliva and drinking plenty of water.

How We Diagnose

  • Breath assessment and medical history
  • Gum & cavity exam + periodontal probing
  • Tongue coating index and saliva flow check (dry mouth)
  • Digital X-rays/OPG to spot hidden infection or food traps
  • Referral to ENT/physician if signs point beyond the mouth

Frequently Asked Questions

Mouthwash masks odour briefly. Fixing the cause—plaque, gum disease, tongue coating, or decay—gives lasting freshness

Yes. The tongue surface harbours odour-producing bacteria. Daily scraping + cleaning cuts VSCs significantly.

Hidden tartar, gum pockets, or food traps between teeth can persist despite brushing. Flossing and professional cleaning are key.

True gastric causes are less common than oral causes. We rule out dental issues first, then coordinate with your physician/ENT if needed.

Many patients notice improvement immediately after cleaning, with further gains over 2–4 weeks as gums heal and habits stabilise.
