What is it?
Breath with odour can originate from the mouth and gums, or occur because of an underlying health problem.
Poor dental hygiene
Untreated dental caries
Bacteria in the mouth
Trapped food in the mouth
Chronic dry mouth
Periodontal (gum) disease
Bloodborne halitosis: in which compounds in the bloodstream are carried to the lungs, then diffused across the membrane in the lungs to enter the breath.
Poor digestive health
Tips to control halitosis:
Control sulphur: Routinely use toothpaste or mouthwash containing zinc compounds to help break down odour-causing sulphur chemicals [iv].
Keep an eye on gum health: Brush and floss regularly to keep gums free of food debris.
Scrub the tongue: Brush your tongue or use a tongue scraper regularly to remove odour-causing substances and keep bacteria in check.
Nutrition and Supplement Support:
Sugar: Focus on eating a balanced diet including foods with high protein and fibre content. Sugar-containing food can cause bacteria to thrive and increase in the mouth. So try to reduce sugar-rich food to improve the breath odour.
Alkalising foods: The consumption of alkalising foods such as raw apples, mint, parsley, and spinach can increase enzyme activities in the body, and naturally deodorise bad bacteria in the mouth [iii].
