Dry Mouth (Xerostomia): Causes, Symptoms, and Treatment

Dry mouth, or xerostomia, occurs when the salivary glands can’t produce enough saliva to maintain a healthy oral environment.

Symptoms of Dry Mouth

Saliva helps us swallow, speak, taste, and digest. If you have a dry mouth, you can experience symptoms such as:

• A dry mouth and tongue
• A tingling or burning sensation in the mouth
• A sore throat
• Persistent thirst
• Stringy and thick saliva
• Difficulty eating, speaking, or swallowing
• Bad breath

Anyone can experience dry mouth on occasion, but persistent symptoms should be evaluated by your dentist or doctor.

How Dry Mouth Affects Your Oral Health

A dry mouth causes more than physical discomfort; it can also significantly affect your oral health.

Saliva helps protect teeth from decay. It neutralizes acidic foods, washes away food particles and bacteria, and contains minerals like calcium and phosphorus that remineralize enamel and support tooth decay prevention.

Reduced saliva production does more than make teeth more vulnerable to decay. In the short term, xerostomia can cause denture discomfort and persistent oral dryness. Over time, untreated dry mouth can lead to infections, sores, mouth ulcers, oral thrush, and even periodontal disease.

Regular visits for dental exams and professional cleaning are essential for identifying early signs of damage caused by reduced saliva.
