Dry mouth, also known as Xerostomia, is a condition where your salivary glands don’t produce enough saliva to keep your mouth moist. While it may sound like a minor inconvenience, saliva plays a crucial role in your oral health. It helps moisten and lubricate your mouth, aids in digestion, cleanses your mouth by flushing out food debris, neutralizes acids produced by bacteria, and prevents infection by controlling bacteria and fungi.
Causes of Dry Mouth
Aging
As we age, our bodies undergo various changes, and a reduction in saliva production is one of them. This makes older adults more prone to experiencing dry mouth.
Dehydration
Not drinking enough water can lead to dehydration, which directly affects saliva production. Staying hydrated is essential for maintaining adequate saliva levels.
Anxiety and Stress
High levels of stress and anxiety can reduce saliva production, leading to a dry mouth. Managing stress through relaxation techniques can help alleviate this symptom.
Mouth Breathing and Snoring
Breathing through your mouth, especially while sleeping, can dry out your mouth. This is common in individuals who snore or have sleep apnea.
Medications
Many medications, such as antihistamines, decongestants, painkillers, and diuretics, list dry mouth as a side effect. If you suspect your medication is causing dry mouth, consult your doctor.
Medical Conditions
Certain medical conditions, including Sjögren’s syndrome, HIV/AIDS, Alzheimer’s disease, diabetes, anemia, cystic fibrosis, rheumatoid arthritis, hypertension, Parkinson’s disease, stroke, and mumps, can lead to dry mouth.
Cancer Therapy
Radiation therapy and chemotherapy used in cancer treatments can damage salivary glands, resulting in reduced saliva production.
Lifestyle and Habits
Habits like smoking, chewing tobacco, and excessive alcohol intake can contribute to dry mouth. Making healthier lifestyle choices can help manage this condition.
Symptoms of Dry Mouth

Diagnosis of Dry Mouth
Diagnosing dry mouth involves several steps:
Medical History
Your doctor will review your medical history to identify any underlying conditions or medications that might be causing dry mouth.
Imaging Scans
Imaging scans, such as sialometry and sialography, help evaluate the salivary glands’ function and structure.
Sialometry
This test measures the flow rate of saliva to determine if it’s below normal levels.
Sialography
A special dye is injected into the salivary glands to highlight any blockages or abnormalities during X-rays.
Biopsy
A small sample of salivary gland tissue may be taken for analysis to identify any underlying conditions like Sjögren’s syndrome.
Management and Treatment of Dry Mouth
