There are many reasons for dry mouth. Consider that patients prefer to eat spicy, stimulating and greasy food in their diet, too much consumption of spicy and greasy food will easily cause fire, and once they get fire, they will feel dry mouth. You can take appropriate drugs to lower the fire, such as Lian Huang tablets and Jin Yin Hua lotion. Oral diseases are not excluded, such as mumps, oral glandular stones, etc., which may lead to oral glandular lesions, resulting in reduced saliva secretion, thus feeling dry mouth. Patients are advised to go to a dental hospital in time to clarify the lesion. If it is oral glandular stones, the stones need to be removed through surgical treatment, and the dry mouth symptoms will be relieved when saliva secretion in the mouth returns to normal. It may also be caused by external reasons, such as dry climate, in a dehydrated environment, also easy to feel dry mouth. Patients are advised to take more fresh fruits and vegetables and drink more water in daily life, which can also relieve the symptoms of dry mouth.
