Bad Breath - Definition

Ask a question


Bad breath, or halitosis refers to breath that has a nauseating scent. These odors may have various origins. For example, food stuck in the teeth or an oral cavity could encourage the proliferation of bacteria involved in breaking down any residue of products that are malodorous. Dental or gum disease can also be the cause. Certain medications or certain foods or alcohol are also frequently involved in a case of halitosis. However, overall poor oral hygiene is generally the main cause of halitosis.
