Acid in the mouth refers to a self-conscious sour taste in the mouth, which is usually a precursor of gastritis, gastroesophageal reflux disease, periodontitis and other diseases.
1. Gastritis: Excessive secretion of gastric acid due to gastrointestinal infection by Helicobacter pylori can cause sour taste in the mouth, accompanied by nausea, abdominal pain, bleeding, fatigue and other symptoms.
2. Gastroesophageal Reflux Disease (GERD): Due to excessive secretion of gastric acid in the body, the slow peristalsis of the intestines and stomach leads to the upward inflow of food containing gastric acid into the esophagus or the mouth causing acid in the mouth, which is accompanied by symptoms such as heartburn, sore throat, heartburn, and so on.
3. Periodontitis: Inflammatory infection of the periodontal tissues causes the gums to shrink, resulting in the exposure of dentin tubules, so that the nerve endings are abnormally sensitive to cause acidity, accompanied by redness and swelling of the gums, tenderness, oral odor and other symptoms.
In addition, do not brush your teeth, eat sweet and sour spicy stimulating food for a long time, mental tension and fatigue and other physiological reasons can also cause sour mouth, it is recommended that daily to maintain oral hygiene, quit smoking and drinking, avoid dental stimulation, moderate exercise, keep a happy mood. When the mouth acidity is severe, we should consult a doctor in time, under the guidance of a professional physician to clarify the cause of the disease, and carry out targeted treatment.
