Dry Mouth

Saliva plays an important role in lubrication, moisture, and oral hygiene. Moreover, it also helps in chewing and swallowing food. When you don’t have enough saliva in your mouth, it can lead to dry mouth and irritation.

A condition in which the salivary glands do not produce saliva is called (dry mouth) or xerostomia or cotton mouth syndrome. It is a symptom or side effect rather than a condition itself. About 10% of the world’s population suffers from xerostomia.

In this blog post, we will understand dry mouth, its causes, symptoms, and treatment options. We will also share some home remedies that you can use to relieve the symptoms of xerostomia.

Dry Mouth (Xerostomia):

It is a condition in which the salivary glands do not produce enough saliva. Salivary glands are located under the tongue, in the mouth, and throat. They produce saliva that serves several roles, including:

  • Preventing tooth decay.
  • Aiding in chewing and swallowing.
  • Washing off food particles.
  • Aiding in digestion.
  • Limiting bacterial growth.

Low saliva production has a major impact on general health. Moreover, it also affects the health of the gums and teeth, as well as your appetite and ability to taste food. If you experience severe dry mouth, it is advisable to consult a general physician as soon as possible.

Fact: Dryness could be more severe at night than during the day because less saliva comes out of the mouth at night.

Causes of Dry Mouth:

Many short-term or long-term conditions can cause dry mouth. Also, it can be a side effect of some things happening in your life. Some major causes associated with dry mouth are:


    • Hundreds of medications, including antihistamines, decongestants, antidepressants, and some blood pressure medications, can cause dry mouth as a side effect.
    • Many over-the-counter (OTC) medications can cause dryness in mouth. Check the medicine leaflet to see if the medicine causes dryness or not.

Sjögren’s Syndrome:

    • Sjogren’s Syndrome is an autoimmune disease affecting salivary glands, sweat glands, and eyes. Dry mouth is a symptom of Sjogren’s Syndrome.

Lifestyle Factors:

  • Unhealthy activities such as smoking, drinking alcohol, or consuming too much caffeine can lead to dry mouth.
  • Methamphetamine, a drug, can damage teeth and cause severe dry mouth (called “Methmouth”). If you smoke, try to cut down, as it not only dries out your mouth but also causes other health problems.

Old Age:

  • Older people take more medications than adults, leading to dryness in their mouth. Additionally, their body’s ability to process drugs changes with age.
  • Poor nutrition and other long-term health problems can also cause xerostomia. About 25% of older people have xerostomia (dry mouth).

Cancer Treatment:

  • Cancer treatments in the upper head or neck, such as radiotherapy or chemotherapy, can cause dry mouth.
  • Radiation to the neck or head area can affect the salivary glands, temporarily reducing saliva production.

Neurological Damage:

  • Facial nerve damage can impair salivary gland function, reducing saliva production.

Medical Conditions:

  • Certain medical conditions such as diabetes, amyloidosis, AIDS, cerebral palsy, primary biliary cirrhosis, Parkinson’s disease, and lupus can cause dry mouth.
  • Dehydration is another factor that can cause dryness in mouth. Drink plenty of water to avoid health problems.
  • A study on the prevalence of xerostomia showed that women experience more dry mouth than men.


  • Viral or bacterial infection of the salivary glands can cause restricted saliva production, such as mumps.

Fact: Women (27.3%) experience more dryness in mouth than men (21.3%).
