How Sugar Fuels Persistent Bad Breath

Bad breath often isn’t just about brushing. When sugar feeds mouth bacteria, they produce acids and foul gases that cause persistent odour. Every time you consume sweets, soft drinks or sugary snacks, oral bacteria break down the sugar and release waste products. This process also weakens tooth enamel and increases plaque buildup, giving bacteria more places to thrive. Even after you brush, if sugar intake stays high the bacteria quickly return and keep producing that unpleasant smell. To fight chronic mouth odour, reduce how often sugar enters your diet in addition to good oral hygiene.
