However, if there is a relevant cause, simply making water and drinking it is only a dietary treatment method, which cannot effectively improve the bitterness of the mouth. Therefore, it is necessary to identify the cause of the disease, and in addition to drinking water, it is also necessary to pay attention to the improvement of diet and living habits, such as reducing the intake of greasy, fried, spicy and stimulating food, as well as quitting smoking and drinking, and avoiding staying up late at night, only under the role of active and comprehensive treatment can the symptoms of bitter mouth be relieved.
