We all know that people with bad teeth usually have bad stomachs. Why is that? General people know the reason is that brushing teeth is not serious, usually the oral cavity is also poor, often have caries and periodontitis, make eating as a gulp, food can not be fully chewed, will increase the burden on the stomach, nutrients can not be fully absorbed will cause gastric problems. Recent scientific findings have deepened people’s understanding of the relationship between toothbrushing and gastric disease. Gastric ulcer, gastritis is a chronic disease, easy to relapse, always good and bad, sometimes light and sometimes heavy, more difficult to cure. In the past, the cause of the disease was either generalized or considered “not yet understood”. In recent years, the research results of many scholars at home and abroad show that it is caused by Helicobacter pylori (Hp). Under the scanning electron microscope, Hp is shaped like a group of white fat like silkworms, non-silkworms, its body was a mild S-shaped curved, one end of the flagellum with a number of sheaths. It hibernates on the surface of human gastric epithelial cells, driven by the flagellum, voraciously peristalsis “foraging”, penetrate the gastric mucus layer, so that people suffer from a variety of gastric diseases, and even develop into gastric cancer. According to the report of China’s malignant tumor cause of death survey in 1995, the mortality rate of gastric cancer is still in the first place in the cause of death of total cancer. The World Health Organization (WHO) has listed Hp as the first cause of stomach cancer. Experts estimate that 50% of stomach cancer in China is related to Hp infection. Where does H. pylori enter the stomach? The “culprit” of these gastric diseases, H. pylori, comes from the mouth! If middle-aged and old people are prone to periodontal disease, there is a large number of H. pylori in the pus. Dental plaque harboring a large number of Helicobacter pylori, when the body’s resistance is low, with saliva or food swallowed into the stomach Helicobacter will “make waves”, leading to the occurrence of gastric disease and recurrence. If the patient can be in the treatment of gastric disease at the same time, adhere to daily brushing, master the correct way of brushing and rinsing after meals, and often replace the toothbrush (because in the contaminated toothbrush, also hidden a large number of Hp), and adhere to the careful brushing of the teeth after each meal, in order to completely remove oral foci in the scale and old toothbrushes in the hidden danger – – Helicobacter pylori, often can receive once and for all the miraculous results. For patients wearing dentures, the brushing here also includes the cleaning of dentures. Keep dentures clean and hygienic, to do after each meal, brush teeth cleaning, sleep at night off, and then put into the mouth in the morning clean. Scrubbing should be put a little toothpaste with a toothbrush along the teeth to brush clear, do not use hot water, do not use alcohol or other liquid soak, so as to avoid deformation and deterioration of dentures. Before going to bed at night, take off the dentures, rinse them with water and soak them in cold water, so that the oral tissues get enough rest to keep the dentures clean. Daily cleaning of dentures will also prevent the occurrence of oral Helicobacter pylori, thus reducing the incidence of gastric diseases.
