What It Is

Dry mouth is a health problem that can contribute to tooth decay and other mouth infections (NHS, 2023; Villa, Connell and Abati, 2014). It is rarely a sign of anything serious, but a dry mouth that does not go away may be caused by a condition such as diabetes or Sjögren's syndrome (NHS, 2023). Dry mouth is not a normal part of ageing (National Institute of Dental and Craniofacial Research, 2024). If you suffer from any of these symptoms, my advice is to inform your doctor and dentist at the first opportunity.

What Is Dry Mouth?

Many people suffer from dry mouth, or xerostomia (pronounced "zero-stoh-me-a"), and have one or more of the following symptoms:

The need to moisten their mouth frequently
Mouth is dry at bedtime
Less saliva is present than before
Difficulty swallowing
Trouble eating foods such as crackers or toast

Most cases of dry mouth happen because the salivary glands are not producing enough saliva. Although dry mouth is not a disease in itself, it can be a symptom of certain diseases. Dry mouth is also a common side effect of some medicines and medical treatments (National Institute of Dental and Craniofacial Research, 2024; NHS, 2023).

What Happens When You Have Dry Mouth?

People with dry mouth have a range of discomfort and symptoms. Some people feel a dry or burning sensation in their mouths or find it hard to chew, taste, swallow and speak. Changes in saliva can also affect oral and dental health. Severe cases of dry mouth can include symptoms such as splitting or cracking of the lips and/or corners of the mouth, changes in the surface of the tongue, rapid tooth decay, ulcers in the lining of the mouth, and infections such as thrush (Villa, Connell and Abati, 2014).

What Causes Dry Mouth?

Less serious cases of dry mouth may be caused by dehydration, for example from not drinking enough or sweating a lot in hot weather or during exercise (NHS, 2023). The easy answer is to drink water. Breathing through your mouth at night, for example because of a blocked nose, can also cause a dry mouth (NHS, 2023).

Medications

Hundreds of medicines can make the salivary glands produce less saliva. For example, medicines for high blood pressure, depression and bladder-control problems often cause dry mouth (National Institute of Dental and Craniofacial Research, 2024). Check the leaflet that comes with your medicine to see if dry mouth is a side effect, but do not stop taking a prescribed medicine without getting medical advice first, even if you think it might be causing your symptoms (NHS, 2023).

Cancer Treatment

Radiotherapy to the head and neck can damage the salivary glands (Villa, Connell and Abati, 2014). Chemotherapy can make saliva thicker, causing the mouth to feel dry (National Institute of Dental and Craniofacial Research, 2024).

Diseases

Sjögren's syndrome is an autoimmune disorder whose symptoms include dry mouth and dry eyes. Diabetes and oral thrush (a fungal infection in the mouth) can also cause a dry mouth (NHS, 2023).

Other

Anxiety, depression and poor nutrition can also be linked to a dry mouth (NHS, 2023; Villa, Connell and Abati, 2014).

Why Is Saliva Important?

Saliva has many important functions in the body, and each person needs an adequate amount to (National Institute of Dental and Craniofacial Research, 2024):

  • Wash away food particles from the teeth and gums, helping to protect against tooth decay and other oral infections
  • Protect teeth with minerals, such as calcium and phosphate, that help keep them strong
  • Keep the soft tissues lining the mouth moist, making speaking and chewing easier
  • Moisten and break down food so it can be swallowed
