Dry and bitter mouth can be caused by various factors. Issues with the mouth and salivary glands, such as reduced saliva secretion, may lead to dry mouth, which could be related to autoimmune diseases, certain medication side effects, or neurological disorders. Problems with the liver and biliary system, such as bile reflux or abnormal liver function, can cause a bitter taste in the mouth. Prolonged dehydration, poor oral hygiene, smoking, excessive alcohol consumption, stress, or anxiety may also contribute to similar symptoms.

In terms of daily care, maintaining good oral hygiene, drinking water regularly to stay hydrated, and avoiding overly spicy or greasy foods can help alleviate symptoms. Adjusting lifestyle habits, such as reducing stress, quitting smoking, and limiting alcohol consumption, can also improve overall health. If dryness and bitterness in the mouth persist, prompt medical attention is recommended.
