Causes of a Dry Mouth

Posted on 9/11/2023 by OM
Causes of a Dry MouthA dry mouth is the reason for many oral issues. When you have insufficient saliva, bacterial plaque will increase, making you prone to cavities and tooth decay. It also leads to speech impediments, chewing and swallowing difficulties, which can affect the quality of your life. For this reason, it is vital to combat mouth dryness, and the best way to achieve this is by understanding the causes. Here are three common causes of a dry mouth:


Dehydration is the leading cause of dry mouth. In most cases, it occurs due to insufficient water in the body. It can also happen if you lose a lot of fluids as a result of certain conditions, such as vomiting or diarrhea. When you have these conditions, replacing the lost water may be challenging.

Exercising during the summer season can also make you lose a lot of water because of excessive sweating. These conditions and activities cause dehydration, which results in a dry mouth.

Certain Medications

A dry mouth can also occur due to some medications. For instance, appetite supplements, antidepressants, analgesics, and other prescription medications can suppress saliva production. Due to this, you will have insufficient saliva to moisturize your mouth. If you think your dry mouth is due to medication, you should seek professional advice.

Mouth Breathing and Snoring

Do you snore or mouth breath at night? People with these habits are prone to dry mouth. Snoring leads to the drying of the air in your mouth and throat. This leaves your mouth dry, as the salivary glands cannot meet the moisture levels to counter outward airflow. Open dry mouth exposes you to bacteria and germs that lead to oral infections.
