Bad breath: the real causes (and real solutions)
90% of bad breath originates in the mouth. Most of it is preventable.
Halitosis (bad breath) has a social stigma far greater than it deserves. It's extremely common and, in most cases, entirely addressable.
Where bad breath comes from
90% of cases originate from the mouth itself, specifically from volatile sulphur compounds (VSCs) produced by bacteria breaking down proteins. The tongue is the primary site, followed by the spaces between teeth and below the gumline.
Only about 10% of cases originate from the gut, lungs, or systemic conditions.
The tongue factor
The surface of the tongue is highly textured and harbours enormous amounts of bacteria. A proper cleaning routine should include tongue scraping. A dedicated stainless steel tongue scraper is more effective than brushing the tongue with a toothbrush.
The morning breath problem
Saliva production drops during sleep, allowing bacteria to proliferate. Morning breath is normal and resolves within minutes of eating, drinking water, or brushing.
Persistent cases
If your breath concerns persist despite good oral hygiene, see your dentist and GP. Persistent bad breath can indicate gum disease, dry mouth, sinus issues, or rarely, systemic conditions.
