Introduction
Bad breath is generally not caused by a deficiency of vitamin B6 or other vitamins. There are many causes of bad breath, commonly seen in gingivitis, dental calculus, and Helicobacter pylori infection. Maintaining good oral hygiene is important—brush your teeth morning and night, rinse your mouth after meals, and use dental floss properly, all of which greatly help maintain oral cleanliness and health.
Bad breath is generally not caused by a deficiency of vitamin B6 or other vitamins. There are many causes of halitosis, commonly seen in conditions such as gingivitis, dental calculus, and Helicobacter pylori infection, but it may also result from poor oral hygiene.
I. Non-disease factors
In some individuals who rarely brush their teeth and frequently consume chives, garlic, chili peppers, or who smoke and drink alcohol, bacteria in the mouth can multiply significantly, leading to bad breath. Brushing teeth regularly and using dental floss at least twice daily—morning and night—can help reduce halitosis.
II. Disease-related factors
1. Gingivitis
When suffering from gingivitis or periodontitis, gum bleeding and increased inflammatory exudate occur. Anaerobic bacteria ferment and break down organic components in blood and exudate, producing volatile sulfur compounds that cause bad breath. Regular teeth cleaning (dental scaling) and rinsing with chlorhexidine solution can help alleviate symptoms.
2. Dental Calculus
Patients with dental calculus may experience bad breath along with gum bleeding and recession if oral hygiene is inadequate. Maintaining good daily dental hygiene and visiting a hospital for professional dental cleaning are recommended.
3. Helicobacter pylori Infection
Helicobacter pylori can cause stomach pain, excessive gastric acid secretion, and indigestion. Excess stomach acid reacts with food, accelerating fermentation, while indigestion delays gastric emptying. Fermenting food produces foul odors and generates gases that travel up the esophagus, expelled via belching or burping, resulting in a rotten smell in the mouth. A quadruple therapy regimen is recommended: amoxicillin + clarithromycin (or levofloxacin, furazolidone) + rebamipide + bismuth potassium citrate, to eradicate the bacteria.
It is advisable to maintain good oral hygiene by brushing teeth morning and night and rinsing after meals, as well as using dental floss appropriately, all of which greatly contribute to oral cleanliness. Diet should be relatively light; avoid raw, cold, spicy, pungent foods such as ice cream, scallions, garlic, chives, stinky tofu, and chili peppers. Also avoid hard-to-digest, greasy foods like fried skewers, fatty pork, and stir-fried beans.
