Saliva is produced in the mouth by salivary glands and consists mainly of water along with electrolytes, enzymes, mucus and antibacterial compounds. It serves various important functions including cleaning the oral cavity, lubrication, maintaining oral health and aiding digestion. A decrease in saliva secretion below normal levels can cause xerostomia or dry mouth. Xerostomia has no direct cure and is typically caused by damage to the salivary glands, certain medications, diseases like Sjogren's syndrome or dehydration. It can lead to issues like difficulty speaking and swallowing, altered taste and increased risk of dental caries. Treatment focuses on identifying and addressing the underlying cause, as well
