Why does saliva smell? What's the matter with saliva smelling?

Some people have bad breath and are even afraid to stand face to face with others, which seriously affects their self-confidence and social skills. Some people think that it is the saliva that smells, but why does the saliva smell? What is going on with the saliva that smells? In fact, it is not because of the bad saliva. The bad smell in the mouth is mostly caused by oral diseases. For example, periodontitis problems such as tooth decay and residual roots can cause bad breath.

1. Why does saliva smell bad?

According to statistics, 80% to 90% of bad breath comes from the oral cavity. Untreated caries, residual roots, residual crowns, poor restorations, abnormal anatomical structures, gingivitis, periodontitis and oral mucosal diseases in the mouth can all cause bad breath. Among them, dental caries and periodontal disease are the most common related diseases. Food residues and plaque often remain in deep caries cavities and under overhangs of poor restorations, and bacteria ferment and decompose them, producing odor. Dental pulp necrosis or suppurative pulpitis can also cause a bad odor if not treated; patients with periodontal disease often have a large amount of tartar and plaque, and the bacteria in the periodontal pockets ferment to produce hydrogen sulfide, indole and ammonia, which produce a bad odor. In addition, periodontal abscesses and pus discharge from periodontal pockets are mostly caused by Staphylococcus aureus combined with periodontal pathogens, which can also emit a foul odor. The quality and quantity of saliva also play an important role. The decrease in the amount of saliva and the increase in organic components such as protein reduce the flushing and buffering effects of saliva, allowing bacteria to multiply and decompose the organic components in saliva, gingival crevicular fluid and food residues, producing a large amount of volatile sulfides, indoles and other substances, causing bad breath.

2. The harm of bad breath

People with bad breath are very likely to develop constipation, hemorrhoids, etc. If patients with bad breath are not treated in time, their gastritis, gastric ulcer and enteritis will often become significantly worse. The number of E. coli in the intestines of people with bad breath is at least 200 times higher than that of other people. The number of Helicobacter pylori in people with bad breath is at least 150 times higher than that in other people. If patients with bad breath are not treated in time, the number of oral flora will increase greatly, and periodontitis, gingivitis, and oral ulcers will occur frequently. Among the gastrointestinal diseases that are closely related to bad breath, the most serious are gastric cancer and gastroparesis. In a survey of patients with gastric cancer and gastroparesis, it was found that these patients' bad breath generally reached the deep standard.
