The image illustrates a common situation: a person is speaking while the other person is bothered by an unpleasant odor coming from their mouth. This phenomenon, called bad breath or halitosis, can have several causes and cause social discomfort.

The main causes of bad breath

Poor oral hygiene: The accumulation of food debris between the teeth encourages the proliferation of bacteria responsible for bad odors.

Gum disease: Gum inflammation and infections often produce a persistent odor.

Dry mouth: a lack of saliva prevents the mouth from cleaning itself naturally.

Odorous foods and drinks: garlic, onion, coffee, alcohol or strong spices leave lasting traces.

Smoking: Tobacco dries out the mouth, alters oral flora and creates unpleasant breath.

General health problems: Digestive disorders, respiratory infections or diabetes can cause halitosis.
