Understanding Dry Mouth in Sjögren's Syndrome
Sjögren's syndrome is a systemic autoimmune disease characterized by lymphocytic infiltration of exocrine glands, such as the salivary and lacrimal glands. This progressive damage to the glands leads to a significant decrease in saliva (hyposalivation), resulting in persistent dry mouth, a condition known as xerostomia. The chronic lack of saliva is not merely uncomfortable; it can lead to several oral health complications, including:
- Difficulty chewing and swallowing
- Changes in taste and speech
- An increased risk of dental caries (cavities)
- The development of oral candidiasis (thrush)
- Inflammation and irritation of the oral mucosa
Because of these issues, finding an effective way to manage dry mouth symptoms is a cornerstone of treatment for Sjögren's patients. Saliva sprays are one of the most convenient and accessible solutions for providing temporary relief.
The Role of Saliva Sprays
Saliva sprays, often called saliva substitutes or oral moisturizers, are formulated to mimic the lubricating and moistening properties of natural saliva. Unlike simply drinking water, which provides only transient moisture, these sprays contain ingredients that help the moisture adhere to the oral tissues for a longer period. Their primary role is to alleviate the discomfort and difficulty associated with chronic dry mouth, helping to improve chewing, speaking, and overall quality of life.
Types of Saliva Sprays and Their Mechanisms
Saliva sprays and other saliva substitutes come in various formulations, each with a slightly different approach to relieving dryness. They can be broadly categorized into over-the-counter (OTC) and prescription products.
Over-the-Counter (OTC) Sprays
OTC sprays are widely available and typically provide quick, short-term relief. Many of these products are water-based and contain ingredients that provide lubrication.
- Cellulose-based sprays: Many formulas use cellulose derivatives, such as carboxymethylcellulose or hydroxyethyl cellulose, to provide viscosity and a coating effect. This helps the spray adhere to the oral mucosa and prolong its moisturizing effect.
- Xylitol-based sprays: Xylitol is a natural sugar alcohol that is not only a sweetener but also has documented benefits for oral health, including promoting saliva production and preventing tooth decay. Sprays rich in xylitol, like Allday Dry Mouth Spray, can both moisturize and stimulate residual salivary flow.
Prescription Sprays
Some oral sprays require a prescription, often because they employ a more advanced or specific mechanism of action.
- Lipid-based sprays: Aquoral is a notable example of a prescription-only, lipid-based oral spray. Its active ingredient is Oxidized Glycerol Triester (OGT), which forms a protective lipid film over the oral mucous membranes. This film acts as a barrier, trapping moisture and providing long-lasting lubrication for up to six hours.
It is important to differentiate between saliva-substituting sprays and oral medications that stimulate natural saliva. For example, pilocarpine (Salagen) and cevimeline (Evoxac) are prescription pills that stimulate the remaining functional salivary glands to produce more saliva. A healthcare provider can determine the most appropriate treatment strategy, which may include using a spray in combination with other methods.
Key Ingredients in Saliva Sprays
Commonly used ingredients in artificial saliva sprays include:
- Xylitol: A sugar alcohol that helps moisturize and has antibacterial properties that combat tooth decay.
- Glycerin: A moisturizing agent that helps lubricate oral tissues and keeps them hydrated.
- Carboxymethylcellulose: A thickening agent that helps the spray cling to the inside of the mouth, extending the duration of relief.
- Aloe Vera: Provides a soothing effect and aids in moisturizing the oral cavity.
- Oxidized Glycerol Triester (OGT): The unique, patented ingredient in the prescription spray Aquoral, which forms a protective lipid film.
How to Use a Saliva Spray
Using a saliva spray is a straightforward process, but following the manufacturer’s instructions is crucial for best results.
- Shake gently: This ensures all ingredients are well-mixed, especially for multi-component or lipid-based sprays.
- Spray into the mouth: Direct the spray toward the inside of your cheeks or under your tongue.
- Swish and hold: Briefly swish the liquid around your mouth before swallowing to coat all surfaces effectively.
- Repeat as needed: Most sprays can be used multiple times a day for continuous relief. Prescription versions may have specific dosing schedules.

Potential Side Effects
Saliva sprays are generally well-tolerated, but some minor side effects can occur, especially with certain ingredients or flavors. These may include:
- Altered taste (dysgeusia)
- Mouth irritation or tingling
- Minor gastrointestinal issues, particularly with high-xylitol products.
Serious allergic reactions are rare but require immediate medical attention. Always consult with a healthcare provider before starting any new dry mouth treatment, especially if you have other medical conditions or are taking other medications.
Other Dry Mouth Treatments for Sjögren's
While sprays are convenient, they are one part of a comprehensive strategy. Other options include:
- Gels: Thicker and more viscous than sprays, gels often provide longer-lasting relief, especially at night.
- Rinses: Moisturizing rinses can be used throughout the day to supplement spray use.
- Lozenges and Mints: Sugar-free lozenges containing xylitol can help stimulate saliva flow.
- Prescription Medications: Systemic medications like pilocarpine and cevimeline can increase the body's natural saliva production.
Conclusion: Finding the Right Solution
Sjögren's syndrome and its associated dry mouth can significantly impact a person's comfort and oral health. Saliva sprays are an effective, convenient tool for managing these symptoms, but the right option depends on individual needs. From readily available over-the-counter products to longer-lasting prescription formulas, a range of choices exists. When considering what is the saliva spray for Sjogren's, it is best to discuss the benefits and limitations of various formulations with a healthcare provider. This will ensure that the chosen treatment provides the most effective and personalized relief, improving both comfort and long-term oral health.
