Causes of Dry Mouth

When you have a lack of saliva in your mouth, it can feel very dry. There are several different causes:

Dehydration: If you do not have enough fluid in your system, this can create dry mouth.

Medication side effects: Hundreds of medications can cause dry mouth as a side effect. The most likely drugs to cause this side effect are those that are used to treat anxiety and depression, antihistamines, decongestants, muscle relaxants and those used to treat Parkinson’s disease.

Gibson_Erica_MG_0169Anxiety: “The hormones that your body secretes when you experience stress can cause your mouth to become dry,” says Erica E. Gibson, MD, family practice physician at Saint Francis Medical Center.

Stones in the salivary ducts: In rare cases, stones can block your salivary ducts, causing a decrease in saliva.

“Treatment depends on the cause,” says Gibson. “Your doctor may decide to change you to a different medication dosage.”
