Why You Might Be Experiencing Dry Mouth

Posted on 3/22/2021 by Dr. Amy Nguyen
Why You Might Be Experiencing Dry MouthA dry mouth occurs when your salivary glands fail to secrete enough saliva. When it happens, you may also experience difficulty in speech and chewing foods, affecting your overall health. A dry mouth may also indicate an underlying disease or condition, side effects of medication, and dehydration. Read on for a more detailed analysis.

Medicine Side Effect

Allergy, cold, asthma, and some hypertension drugs cause a dry mouth by limiting the amount of saliva secreted by the salivary glands. Some sedatives and muscle relaxants can also trigger mouth dryness. In cancer patients, radiation and chemotherapy treatments can damage their salivary glands, limiting salivary flow. Thus, if you experience dry mouth after taking this medication, you should talk to us for other options to prevent mouth dryness. Alternatively, you can sip water continuously or chew sugar-free gum to stimulate saliva production.

Underlying Medical Conditions and Diseases

Sjogren's syndrome is an example of a condition that causes dry mouth. This condition causes the immune system to attack the salivary glands, causing mouth dryness. A biopsy test of the antibodies associated with this disorder will help determine whether your dry mouth results from this condition. Individuals with Parkinson's disease will also suffer mouth dryness due to excessive drooling. Other conditions that cause mouth dryness include depression, anemia, and diabetes.


Dehydration can occur if you fail to drink enough water. It can also result from conditions such as excessive diarrhea, vomiting, sweating, and burns. Dehydration will cause mouth dryness and predispose you to gum disease and bad breath. Lifestyle factors such as breathing through your mouth, smoking cigarettes, and using other tobacco products may also cause dry mouth. Given the above causes of dry mouth, treatment will vary depending on the cause. However, to reduce the impact of dry mouth on your overall health, you should brush your teeth using fluoride toothpaste after meals. For more details on dry mouth, contact our office today.
