Bad breath, also known as halitosis, is more common than most people think. It can be temporary or persistent, and it often stems from a mix of oral and lifestyle factors. One of the most frequent causes is the buildup of bacteria in the mouth, especially on the tongue and along the gumline. These bacteria break down food particles and release sulfur compounds, which are responsible for that unpleasant odor.
Other contributors include dry mouth, poor oral hygiene, smoking, certain medications, and strong-smelling foods like garlic and onions. In some cases, digestive issues or underlying health conditions may also play a role. Because so many factors can be involved, addressing bad breath usually requires a combination of good oral care habits and lifestyle adjustments.
