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.
