It is a persistent lack of saliva production even after the intake of water or other fluids. When the dry mouth is caused by dehydration, proper saliva function can restore it within a day. It can be overcomed by drinking lots of fluids.

However, if the salivary gland does not function properly even after the intake of proper nutrition and fluids, then you may be suffering from Xerostomia.

In simple words, Xerostomia is caused due to medical side effects, dehydration, vitamin deficiencies, which ultimately leads to the malfunction of the salivary gland.

Causes of Dry Mouth


Dry mouth is one of the side effects of more than 400 types of medicines. Drugs for allergies, high blood pressure, mental health problems, overactive bladder can also trigger it. Here are some other factors that can cause dry mouth.

You can suffer from dry mouth because of physical conditions. Any traumatic damage to the salivary gland, medicine, diabetes, etc can result in dryness in the mouth. If you have cancer, chemotherapy drugs can also change the nature and amount of saliva production.

2. Autoimmune Disease

Dry mouth can be a result of an underlying medical issue. You may be suffering from an autoimmune disease, Sjogren’s syndrome. This disease attacks the glands in your body that produce tears and saliva.

3. Medications

In some cases, a dry mouth can be the result of drugs or contaminated water. The microbes in water can make your mouth feel dry even after drinking water. Drinking infected water can result in strange health conditions. Viruses and bacteria can infect your mouth or cause dehydration as well.

4. Habit of Snoring

Breathing through your mouth all night can leave your mouth feeling like a desert. Unless you have a bed partner, you might not be aware of the fact that you snore and it is giving you a dry mouth.

However, if you experience a dry mouth as soon as you wake up in the morning, you might be someone who snores. You can get medical help to get your alleged snoring under control.
