Everyone experiences a dry mouth from time to time. You can develop a dry mouth due to a number of reasons – with the most common causes being stress and dehydration. Dry mouth happens when the salivary glands fail to work as they should. If you’re a smoker, abuse drugs and/or alcohol, or are undergoing cancer treatment (such as radiation and/or chemotherapy), it is not uncommon to develop dry mouth.
Certain autoimmune disorders, like Sjogren’s syndrome, can also cause a dry mouth, as can certain medications. In fact, there are over 500 medications known to cause dry mouth, including but not limited to antihistamines, antidepressants, antiemetics, medications used to control blood pressure, as well as sedatives. If you do develop a dry mouth and suspect it may be a result of a medication that you are taking, Dr. Ali Ghahary notes that it is important for patients to know that they should not abruptly stop medications before checking with their family doctor or pharmacist. If medication is a suspected cause of dry mouth, your physician may be able to alter its dosage to see if that makes any difference, or might even recommend a different medication all together.
There are also certain things that doctors, dentists and pharmacists also suggest patients try themselves for relief of dry mouth. For example, chewing sugar-free gum or sucking on sugar-free candy can often help to stimulate the salivary glands, drinking plenty of water during the day, as well as using a humidifier in your home – especially at night. Using an alcohol-free mouth rinse can also help.
If these home remedies are not helpful and you find that you are still suffering from a dry mouth, your doctor and/or dentist may need to prescribe you with a medication to help the function of the salivary glands, especially if you have any underlying medical conditions – like Sjogren’s syndrome – as mentioned above, in addition to lupus or rheumatoid arthritis. Treating whatever the underlying cause is will often resolve other associated problems.
