What causes bad breath? - Mel Rosenberg

The video discusses halitosis, or bad breath, a condition that has troubled humans since ancient times. It explains that bad breath is primarily caused by bacteria in the mouth that produce foul-smelling compounds. These bacteria feed on food remnants and dead cells, breaking them down into smaller molecules that release unpleasant odors. The video highlights the social impact of bad breath, noting that many people avoid dating those with it. Fortunately, bad breath can often be treated with proper oral hygiene, though some cases may require medical attention. The video also addresses the challenge of self-detecting bad breath and suggests asking a friend for feedback.
