What Causes Cottonmouth?

Dry mouth is a popular topic in the oral health field currently due to its increasing prevalence. It can come at very inconvenient times and also cause unfortunate side effects such as bad breath. Let’s look at why you might be experiencing dry mouth and some ways you can combat it.


Smoking is known to cause a multitude of health issues. Inhalation of any smoke damages more than your lungs. The act of smoking dries the mouth and introduces volatile sulfur compounds, which both smell stinky and break down soft tissue. This leads to gingivitis and tooth decay.

Saliva is extremely important to your oral health, it helps get rid of leftover food particles in your mouth and also consists of minerals which repair your tooth enamel. When you inhale smoke it slows saliva production, causing dry mouth.


This one may be fairly obvious, but if your mouth feels dry try drinking more water! Dehydration causes a lack of saliva production which is why your mouth will feel dry when you’re not drinking enough water. The Mayo Clinic recommends you drink 3 liters of water per day for males and 2.2 liters of water for females.

Specific Diseases and Medications

Certain diseases can cause dry mouth as a side effect. Sjögren’s syndrome, HIV/AIDS, Alzheimer’s disease, diabetes, anemia, cystic fibrosis, rheumatoid arthritis, hypertension, Parkinson’s disease, stroke, and mumps are all disease where dry mouth could occur as a side effect. It’s common for medications treating these diseases to have dry mouth as a side effect.
