Does saliva smell bad?

Not all saliva smells bad. Bad saliva may be caused by oral or stomach diseases.

1. Oral diseases: Saliva refers to the saliva in the mouth, which has no smell under normal circumstances. If the oral cavity is not cleaned properly, food residues may remain on the surface of the teeth, which may corrode the teeth and cause caries or periodontal disease. This will cause bad smell in the mouth and the saliva may also smell bad. At this time, you need to go to the oral department of the hospital for examination. If the caries is not too serious, you can fill it with resin materials. After the local filling, the teeth will return to normal and the phenomenon of bad saliva can be alleviated.

2. Stomach diseases: Bad eating habits or eating unclean food can easily lead to Helicobacter pylori infection in the stomach. Patients will experience symptoms such as loss of appetite, stomach pain, weight loss, and bad breath. They need to go to the internal medicine or gastroenterology department of the hospital for examination in time. The condition can be determined through urea breath test and gastroscopy. Under the guidance of a doctor, they can take oral anti-inflammatory drugs such as clarithromycin or metronidazole for treatment.

You need to keep your mouth clean and maintain good eating habits to avoid affecting the health of your mouth and stomach.
