Bitter mouth may be caused by poor oral hygiene, but also due to oral diseases, liver and gallbladder diseases, gastrointestinal diseases, kidney disease, other chronic diseases.
1. Poor oral hygiene: due to the accumulation of a large number of food debris, soft dirt, bacteria on the surface of the teeth and tongue, it is easy to lead to the bitter mouth.
2. Dental or periodontal diseases in the mouth: for example, multiple teeth have caries, pulpitis, apical periodontitis, wisdom tooth pericoronitis, or extensive ulceration of the mucous membrane, leading to an increase in the number of disease-causing factors in the mouth, which leads to the symptom of oral bitterness.
3. Liver and gallbladder diseases: chronic hepatitis, cholecystitis, gallstones and other diseases, can lead to poor bile drainage, back into the mouth, resulting in a bitter mouth.
4. Gastrointestinal diseases: such as peptic ulcer, enteritis, gastritis, functional dyspepsia, etc., can cause abdominal distension, resulting in a bitter mouth.
5. Kidney disease: when some people have kidney function problems, such as nephritis, kidney stones, renal insufficiency and other kidney diseases, it is also easy to appear in the mouth with a sense of odor, such as salty mouth, bitter mouth and so on.
6. Chronic diseases: such as diabetes, hypertension, hyperlipidemia, etc. will also affect the sense of taste, resulting in abnormal oral taste. Diabetes, which is common among the elderly, can lead to a decrease in fluid secretion, which can easily make the patient feel dry and bitter in the mouth.
