Moistir® is a saliva substitute designed to help coat, lubricate, and protect dry oral tissues with a gentle, saliva-like spray.

Moisture balance is a familiar topic in wound care discussions. But it’s less common to consider oral moisture, despite dry mouth being a frequent symptom among those recovering from complex wounds. Xerostomia (persistent dry mouth) can be triggered by surgery, respiratory support, oncology treatment, dialysis, autoimmune conditions, medications, advanced aging, and more—conditions often seen in the same settings as complex wounds. 

As oral tissues dry out, minor discomfort can quickly escalate into irritation, cracks, fissures, and greater oral health risks. Dry mouth can also make it harder for patients to speak, swallow, eat, and stay comfortable during recovery.

A synthetic saliva spray like Moistir helps address this discomfort, lubricating and protecting oral tissue and offering fast relief while supporting better patient outcomes.

What is a saliva substitute?

A saliva substitute is an oral care product that uses electrolytes and minerals to help improve oral moisture, mimicking the body’s natural response to dry mouth even when underlying factors prevent normal saliva production. It doesn’t stimulate the body to produce more saliva, but it can help relieve the discomfort of dry mouth by coating and hydrating oral tissues in a way that feels natural. These products are also sometimes referred to as saliva replacements or synthetic saliva sprays, depending on the formula and format.

Saliva substitutes may be especially helpful when xerostomia is related to medical treatment, hospital procedures, medication side effects, reduced fluid intake, or systemic conditions. 

How the Moistir synthetic saliva spray works

Moistir is a non-therapeutic, aqueous solution formulated with Sodium Carboxymethylcellulose and several electrolytes found in normal human saliva. It provides topical moisture directly to the mouth, creating an instant saliva-like feel for patients whose natural oral moisture is reduced or disrupted.

What’s in the saliva replacement?

  • Sodium Carboxymethylcellulose. This helps give Moistir body and viscosity, allowing the solution to coat oral surfaces instead of disappearing immediately.
  • Potassium Chloride, Dibasic Sodium Phosphate, Calcium Chloride, Sodium Chloride, and Magnesium Chloride. These key electrolytes are found in normal human saliva and help Moistir more closely mimic its natural composition.
  • Methylparaben and Propylparaben. Both act as preservatives to extend Moistir’s effective shelf life.
  • Mild mint flavor. The refreshing flavor helps make routine use more pleasant for patients.

How to Use Moistir for dry mouth

Moistir saliva substitute can be added to a patient’s oral care routine as a simple, ready-to-use dry mouth spray. For general use, dispense Moistir directly into the mouth as needed to help restore moisture and comfort.

In healthcare settings, Moistir may also be applied to swabsticks for more controlled coverage of the oral mucosa, tongue, lips, gingival tissue, and other dry or sensitive areas. This can be especially useful for patients who need assistance with oral care or who may have difficulty using a spray independently.

Routine use can help patients maintain oral moisture throughout the day, supporting comfort with speaking, swallowing, eating, and rest during recovery.

When should clinicians (and their patients) consider using Moistir?

Moistir may be useful for patients experiencing xerostomia due to medical treatment, procedures, medication use, or systemic conditions. In wound care and recovery settings, this may include patients recovering from surgery, receiving oxygen therapy, experiencing intubation or suctioning, taking prescription or over-the-counter medications, or managing reduced fluid intake due to hemodialysis.

Moistir may also support patients dealing with dry mouth related to radiation or chemotherapy, autoimmune conditions like Sjögren’s Syndrome, mouth breathing from congestion or untreated sleep apnea, advanced aging, stress, extensive speaking, sports, or exercise. For care teams, it offers a simple way to address dry mouth before discomfort interferes with speaking, swallowing, eating, or overall patient comfort.
