Is there Helicobacter pylori in the mouth of normal people?
Helicobacter pylori may also exist in the oral cavity of normal people, because the oral cavity is also the main transmission route of Helicobacter pylori, such as dental plaque, gingival pocket, dental caries, dental pulp, back of tongue, saliva and so on. After colonization in the oral cavity, Helicobacter pylori will be swallowed with saliva and continuously enter the stomach, thus causing stomach diseases such as gastritis and gastric ulcer.

The colonization of Helicobacter pylori in the oral cavity is also an important reason for the failure of eradication, recurrence or reinfection of Helicobacter pylori.

However, drugs have little effect on HP in saliva, gingival crevicular fluid and dental plaque, especially the bacteria in dental plaque have a unique "biofilm" structure, so drugs are difficult to reach and play a role.

Keep your mouth clean, brush your teeth every morning and evening, and don't rush things. The cleanliness of teeth is not enough, and Helicobacter pylori can easily multiply on teeth. Also, rinse your mouth after every meal. Maintain oral hygiene, develop good habits and prevent infection with Helicobacter pylori.
