This is caused by volatile chemicals in the circulation that transfer to the lungs during alveolar gas exchange and come out in the breath.  Most of these chemicals are produced by your body.  The concentration of these chemicals in your breath reflect their concentration in your blood.  Examples of these chemicals include alkanes, hydrocarbons, and […]

From the desk of Bassel Paul Gebrael DDS, Dip. Perio, FRCD(C), FICD Type 3 halitosis is caused by the leakage of odorant volatile molecules from the stomach through the esophagus. Gastroesophageal reflux (belching) occurs several times a day and is considered normal. It can produce mild odour as a normal physiological process. Gastroesophageal halitosis can […]

From the desk of Bassel Paul Gebrael DDS, Dip. Perio, FRCD(C), FICD Type 2 bad breath originates from the respiratory tract all the way from your nose down to your lungs and could be the result of inflammation due to allergy or obstruction and/or a viral or bacterial infection. This kind of bad breath that […]

Simple portable devices that measure Hydrogen Sulfide gas are available at Walmart or Amazon. Bad breath is most likely caused by bacteria breaking down food particles and your own tissues and releasing sulfur gas.  Bad breath that won’t go away can be a sign of active gum disease, although there are other causes of bad […]

a) Use a tongue scraper to reduce malodorous coating on the tongue and floss or use a water pik to remove particles of food between the teeth.  b) Get a dental checkup to rule out active gum disease or other mouth disease or poorly fitted dental crowns and bridges that can trap food particles.  c) […]

The gases that come out of the mouth that cause bad breath are volatile sulfur compounds, including hydrogen sulfide and methyl mercaptan. They can be generated by bacteria due to gum infection (gum disease)  Morning breath, which can occur when you wake up, is caused by the breakdown of food particles overnight by bacteria.  The […]

Bad breath can originate from causes outside the mouth: a) Bad breath from the nose and tonsils and airway: This can be a cause of bad breath due to bacterial infection.

Halitophobia is when a patient fears he has bad […]

Volatile Sulfur Compounds (VSC) like hydrogen sulphide are produced by gum disease causing bacteria and are a cause of bad mouth odour.  According to a study by Morita, sulfur levels were higher in patients with more severe gum disease. If you have persistent bad mouth odour, this may be a sign of active gum disease.  […]
