What are some causes of dry mouth?

Dry mouth: Common causes in my practice include anticholinergic side effects of medication, such as antidepressant or antihistamine meds, mouth breathing due to sinus or nasal problems, dehydration from vomiting, diarrhea, and uncontrolled diabetes. It can be caused by autoimmune diseases such as sjogren's syndrome.

Dry mouth: Dry mouth has a lot of causes. Common causes are medications, especially diuretics. Other causes can be lack of adequate water intake, stress or rarely autoimmune disease (i.e., sjogrens syndrome).

Medications: Many medications can cause a dry mouth. So check with your doctor or pharmacist if you are taking any meds. Allergies, mouth breathing, dehydration, the dry winter air can be causes also. Dry mouth can cause tooth decay so if your mouth is dry talk to your dentist about ways to protect your teeth.
