Persistent Bad Breath from Gums
Bad breath originating from the gum tissue often signals underlying periodontal inflammation.
Overview
Bad breath (halitosis) has many possible origins, but persistent halitosis that comes back after brushing is commonly linked to the gums. Bacteria in periodontal pockets produce volatile sulphur compounds that are responsible for the characteristic odour.
A periodontal assessment reliably identifies whether gum disease is contributing. If so, the breath usually improves significantly once the pockets are cleaned and the disease is stabilised.
Treatment combines hygiene therapy, targeted tongue care, and home-routine coaching. For patients with advanced periodontitis, an ongoing maintenance schedule keeps the breath fresh long-term.
