Dry Mouth: Causes, Symptoms, and Solutions

Dry mouth, medically known as xerostomia, is more than just feeling thirsty — it’s a common condition that affects your oral health and daily comfort. Saliva plays a vital role in keeping your mouth moist, protecting your teeth, and aiding digestion. When saliva production decreases, problems can arise.

In this article, we’ll explore the causes of dry mouth, how to recognize its symptoms, and what you can do to find relief.

What Causes Dry Mouth?

Several factors can reduce saliva flow, including:

  • Medications: Many prescription and over-the-counter drugs list dry mouth as a side effect. Common culprits include antihistamines, antidepressants, and blood pressure medications.

  • Dehydration: Not drinking enough fluids or losing fluids through sweating or illness can dry out your mouth.

  • Medical Conditions: Diabetes, Sjögren’s syndrome, and autoimmune diseases can impact saliva glands.

  • Radiation Therapy: Treatments for head and neck cancers can damage salivary glands.

  • Nerve Damage: Injury or surgery affecting the nerves that control saliva production.

  • Lifestyle Habits: Smoking, alcohol use, and excessive caffeine can contribute to dry mouth.

Signs and Symptoms to Watch For

  • Persistent dry or sticky feeling in the mouth

  • Difficulty swallowing or speaking

  • Cracked lips or mouth sores

  • Burning sensation or altered taste

  • Increased thirst

  • Bad breath

  • More frequent cavities or gum disease

Why Is Saliva Important?

Saliva helps:

  • Neutralize acids from food and bacteria

  • Wash away food particles

  • Protect teeth from decay and infection

  • Keep tissues in your mouth moist and comfortable

Without enough saliva, you’re more prone to tooth decay, infections, and discomfort.
