Like many health conditions, halitosis can be caused by several factors. Most of the times, it is originated by an issue in the oral cavity —usually an accumulation of bacteria and food remnants that results in smelly gaseous compounds, known as VSCs.1,2
Some unhealthy lifestyle habits can also cause bad breath like cigarette smoking or alcohol abuse. Certain foods are popular for causing oral malodour too, like onions and garlic. Even some underlying medical conditions may manifest with bad breath as a symptom.1

However, poor oral hygiene and accumulation of bacteria is the source in 90% of the halitosis cases.2,3
Research has confirmed that the presence of caries, gingivitis and periodontitis increases the incidence and intensity of bad breath.4
This is because the saliva from individuals with periodontitis —or gum disease— contains a significantly
greater number of bacteria than those with healthy mouths. These bacteria are retained in the periodontal pockets, making it difficult to remove them with a toothbrush.1,4
