Dry Mouth is a condition that affects people all over the world, but what is the cause and what can be done to prevent it? According to WebMD, there are several reasons you may be suffering from Dry Mouth.


Your dentist explains that a number of things including prescription and over the counter medications causes dry Mouth. If you suspect that the drugs you are taking are causing your chronic dry mouth talk to your doctor who can prescribe something else.


If you are dehydrated, it can also be to blame for your pasty Dry Mouth. If you do not drink enough water, the mucous membranes inside your mouth will begin to dry on causing a decrease in your saliva. If you are constantly dry after strenuous physical activity, make sure you take water with you.

The Weather

Believe it or not, the weather could be the cause of your Dry Mouth. Check your humidity levels as dry climates will leave you parched because of shrunken mucous membranes. Make sure to stay hydrated and drink plenty of water as Dry Mouth can also make you more susceptible to allergies, flues and the common cold. If Dry Mouth is chronic, you may want to purchase a humidifier.

Tooth Decay

If you do not practice good oral hygiene that includes brushing twice and flossing once each day, a healthy diet and regular checkups with your dentist, you could suffer from tooth decay. Gradual decay will eventually cause a reduction in your saliva under your tongue, which could cause chronic Dry Mouth. Scheduling regular checkups with your dentist can help prevent cavities and gum disease.

Damage to your Nerves

If you have suffered a neck or head injury, you could have nerve damage. If your salivary glands nerves have been damaged your brain may not be getting the right messages when it comes to saliva production.

Autoimmune Disease

If you have a dry nose and Dry Mouth, it could be an early indication of an autoimmune disease such as Sjogren’s Syndrome or Crohn’s Disease. Patients who have HIV are also more prone to chronic Dry Mouth.


Chronic Dry Mouth is one of the first signs of Diabetes as it occurs when your blood sugar levels are too high. If this happens, your ketones will lose fluid causing inadequate levels of saliva. This will result in Dry Mouth and severe dehydration making it difficult to chew or swallow food.
