Saliva substitute

Saliva substitute refers to a range of over-the-counter artificial preparations designed to temporarily relieve symptoms of dry mouth (xerostomia) by mimicking the lubricating and protective properties of natural saliva. These substitutes typically contain water, cellulose derivatives or thickeners (e.g., carboxymethylcellulose, sorbitol, glycerol), sometimes with added electrolytes, flavoring agents, or pH buffers. Unlike biological targets, saliva substitute is a symptomatic replacement that does not modulate endogenous pathways or molecular targets; it acts locally by wetting and protecting the oral mucosa. Artificial saliva is offered in forms such as sprays, lozenges, gels, rinses, and mouthwashes. There is no universal equivalent to the complex mixture of proteins, mucins, and antimicrobial peptides found in natural saliva. These products are mainly intended for patients who cannot use salivary stimulants or whose salivary gland function is irreversibly impaired.
