Oral Dryness Treatment: Modern Approaches and Advancements in Xerostomia Care

Oral dryness, medically known as xerostomia, is a common condition characterized by reduced saliva production that leads to discomfort, difficulty in speaking and swallowing, altered taste, and increased risk of dental complications. It can significantly impact a patient’s quality of life, especially when it becomes chronic due to underlying diseases or long-term medication use.

Global Xerostomia Therapeutics Market is currently valued at USD 2.31 billion in 2025 and is anticipated to generate an estimated revenue of USD 3.32 billion by 2034, according to the latest study by Polaris Market Research. Besides, the report notes that the market exhibits a robust 4.1% Compound Annual Growth Rate (CAGR) over the forecasted timeframe, 2026 - 2034

 

Understanding Oral Dryness (Xerostomia)

Oral dryness occurs when the salivary glands fail to produce sufficient saliva to keep the mouth moist. Saliva plays a vital role in oral health, including:

  • Lubricating the mouth for speech and swallowing
  • Protecting teeth from decay and infection
  • Supporting digestion and taste perception
  • Maintaining oral tissue health

When saliva production decreases, patients experience symptoms such as dry tongue, burning sensation, cracked lips, bad breath, and difficulty eating dry foods. In severe cases, it can lead to dental caries and oral infections.

Common Causes of Oral Dryness

  1. Medication Side Effects

More than 400 medications can cause dry mouth, including antidepressants, antihistamines, antihypertensives, and sedatives.

  1. Cancer Treatments

Chemotherapy and head & neck radiation can damage salivary glands, making xerostomia a frequent complication in oncology patients.

  1. Autoimmune Disorders

Diseases such as Sjögren’s syndrome directly attack salivary glands, leading to chronic dryness.

  1. Lifestyle Factors

Smoking, alcohol consumption, caffeine intake, and dehydration can worsen symptoms.

  1. Aging

Older adults are more prone to oral dryness due to natural reduction in salivary gland function and multiple medication use.

Oral Dryness Treatment Options

Treatment for xerostomia focuses on symptom relief, saliva stimulation, and prevention of complications.

  1. Saliva Substitutes

Artificial saliva products are commonly used to mimic natural moisture in the mouth. These are available as:

  • Oral sprays
  • Gels
  • Mouth rinses
  • Lozenges

They help maintain lubrication and provide temporary relief from dryness.

  1. Salivary Stimulants

These medications activate remaining salivary gland function to increase natural saliva production.

Common stimulants include:

  • Pilocarpine
  • Cevimeline

They are often prescribed for patients with moderate to severe xerostomia, particularly those with Sjögren’s syndrome or radiation-induced dry mouth.

  1. Oral Moisturizing Products

Over-the-counter solutions such as sugar-free chewing gum, lozenges, and moisturizing toothpaste help stimulate saliva flow naturally and improve comfort.

These products are widely used because of their accessibility and affordability, making them a key segment in the Xerostomia Therapeutics Market.

  1. Prescription Therapies

For severe cases, healthcare professionals may prescribe targeted medications or therapeutic agents that address underlying causes of salivary dysfunction. These treatments are especially important in cancer-related xerostomia cases.

  1. Lifestyle and Home Remedies

Simple daily habits can significantly improve oral dryness symptoms:

  • Drinking frequent small sips of water
  • Avoiding caffeine, alcohol, and tobacco
  • Using humidifiers at night
  • Practicing good oral hygiene
  • Chewing sugar-free gum

Advances in the Xerostomia Therapeutics Market

The Xerostomia Therapeutics Market is evolving rapidly due to increasing demand for effective dry mouth treatments and innovations in oral care formulations.

Key developments include:

  • Long-lasting mucoadhesive saliva gels
  • Improved oral sprays with extended hydration effects
  • Biologic therapies targeting salivary gland regeneration
  • Digital health integration for symptom tracking
  • Novel drug delivery systems for better absorption

Pharmaceutical companies are also focusing on therapies that address the root cause of salivary gland dysfunction rather than just providing temporary relief.

Challenges in Oral Dryness Management

Despite treatment advancements, several challenges remain:

  • Temporary effectiveness of saliva substitutes
  • Side effects of prescription stimulants
  • High cost of long-term therapies
  • Limited treatment for irreversible gland damage
  • Underdiagnosis of mild xerostomia cases

These challenges continue to drive research and innovation in the market.
