Xerostomia can be caused by dental disease, bacteria, and/or hygiene, along with any number of medical conditions and medical therapies. Painkillers, diuretics, you name it - the fact is that the drugs we take for everything from depression or diarrhea can cause dry mouth as an annoying side effect.
What causes dry mouth? Dry mouth or xerostomia is due to salivary gland shutdown, decreasing the amount of saliva flow inside of your mouth. It can be due to uncontrolled or underlying health conditions, but may also be associated with common everyday prescription medications, nutritional practices and the oral hygiene products that you use. Dry mouth can also appear suddenly, such as with anxiety or nervousness.
