Everyone has been exposed to oral diseases. I believe many friends have experienced toothache, and that feeling is very painful. I hope the blow is one-off, and I don't want to do it again. Experts pointed out that although oral diseases occur in the oral cavity, they may affect the whole body and the health of the whole person. 1, a large number of studies on diabetes show that diabetes and periodontal disease have the same risk factors, and periodontitis and diabetes have a two-way relationship and are high-risk factors. Studies have shown that diabetic patients are often complicated with different degrees of oral diseases. In the diabetic population, the incidence of periodontal disease is high, and the lesions are seriously damaged and progress faster. At the same time, the blood sugar control of insulin-dependent diabetes patients with severe periodontitis is obviously worse than that of patients without periodontal disease. 2, affect the growth and development of chewing function, lead to partial eclipse, loss of appetite, lead to weakened gastrointestinal digestion and absorption, malnutrition, growth and development are affected. 3, cardiologists pointed out that the pathogenic bacteria of oral diseases and their toxins can invade the blood, can produce related antibodies, lectins and so on. , aggravate or cause subacute infective endocarditis, coronary heart disease and other heart diseases. A large number of studies have confirmed that periodontitis is an independent risk factor of acute attack of coronary heart disease, which is significantly related to acute attack or total mortality. 4, dental disease-related arthritis, kidney disease, eye disease experts said that dental disease is not treated in time, forming infected lesions at the root, which can induce arthritis, nephritis, eye disease and so on. This is well known in the medical field, so we should not underestimate dental diseases just because of minor illnesses. 5, experts in gastrointestinal diseases, food absorbs nutrition through mechanical digestion and chemical digestion. The first stage is mechanical digestion, which is chemical digestion after being mixed with saliva when fully chewing and chewing food in the mouth, and then swallowed into the stomach, digested and absorbed by gastric juice and intestinal juice. Poor oral hygiene, some pathogenic bacteria will multiply in the stomach. Studies have proved that gastritis is caused by Helicobacter pylori, and Helicobacter pylori is also detected in dental plaque of unclean mouth. Drugs can easily remove Helicobacter pylori in the stomach and intestines, but it is difficult to remove Helicobacter pylori in dental plaque, which becomes a bacterial bank. 6. Cerebral vascular diseases and periodontitis induce myocardial infarction. Like coronary heart disease, periodontitis can also induce ischemic stroke. Periodontitis has become a risk factor for stroke, coronary heart disease and myocardial infarction. Studies have proved that periodontitis, as a risk factor of stroke, is greater than smoking and independent of other known risk factors. 7. Respiratory disease experts say that oral diseases are closely related to aspiration pneumonia caused by various reasons. According to relevant statistics, 80% of the cause of pneumonia is inhalation of secretions containing bacteria in the mouth and pharynx, and most of these secretions come from the mouth.
