Dry mouth (xerostomia) may make it difficult for you to eat, talk,
swallow, wear dentures, or taste food. In most cases, home treatment will
relieve symptoms of a dry mouth. An ongoing dry mouth can lead to mouth
infections, gum disease, and dental cavities.
Some causes of dry mouth include dehydration, breathing through your
mouth, stress or anxiety, and problems with the function of the salivary
glands.
A dry mouth can also be caused by a medication, such as a diuretic,
antihistamine, or decongestant. If you suspect a medication is the cause of
your dry mouth, call the health professional who prescribed the medication to
determine whether you should stop taking it or take a different one. An
appointment may not be necessary. If you are taking a nonprescription
medication, stop taking it. Call your health professional if you feel you need
to continue the medication.
