Identified non-obvious causes of bad breath

Bad breath can be a signal not only of dental problems - British expert reveals unexpected causes

The President of the British Academy of Cosmetic Dentistry, Sam Jethwa, in an interview with the Daily Mail, dispelled the common misconception that bad breath is always associated with oral diseases. According to the specialist, the root of the problem often lies in diet and the condition of the digestive system.

The dentist explained that unpleasant odor occurs mainly due to the active reproduction of bacteria in the mouth. Dry mouth combined with insufficient hygiene creates ideal conditions for microbes that feed on food residues.

The doctor also pointed to the connection between diet and bad breath.

"Dairy and protein products release amino acids that serve as a nutrient medium for microbes on the tongue. And acidic foods, such as citrus fruits or tomatoes, can stimulate their growth," the expert explained.

Dr. Jethwa noted that "stale" breath may signal gastroesophageal reflux - a condition in which stomach contents are thrown back into the esophagus. A particularly alarming sign is the smell of hydrogen sulfide or rotten eggs - this may indicate serious disorders in the gastrointestinal tract.

The dentist recommended following simple rules: regularly brush teeth and tongue, use dental floss once or twice a day, and replace the toothbrush every three months. If the unpleasant odor persists even with careful hygiene, the British expert advises not to delay visiting a general practitioner.
