[9] [10] Saliva also acts as a natural buffer to neutralize acid, preventing demineralization in the first place. If there is reduced saliva flow or reduced saliva quality, this will increase the risk of demineralization and create the need for treatment in order to prevent demineralization progression. [4]
Saliva on a baby's lips. Saliva (commonly referred to as spit or drool) is an extracellular fluid produced and secreted by salivary glands in the mouth.In humans, saliva is around 99% water, plus electrolytes, mucus, white blood cells, epithelial cells (from which DNA can be extracted), enzymes (such as lipase and amylase), and antimicrobial agents (such as secretory IgA, and lysozymes).
For example, it creates a physical disturbance to microbes through a washing action. Increase in saliva flow via stimulation (i.e. chewing gum) has been shown to diminish cariogenic plaque formation. [12] Saliva is also largely responsible for environmental pH, water content, nutrients, and host-produced immune cells and antimicrobials.
Artificial saliva for dry mouth in a mouthwash form. Artificial saliva or salivary substitutes refer to a synthetically produced liquid that mimics the natural secretion of saliva. It is designed as a symptomatic relief for xerostomia, a condition characterised by dryness in the mouth and is available over-the-counter.

Digestion: Saliva contains amylase, which hydrolyses starch into glucose, maltose, and dextrin. As a result, saliva allows some digestion to occur before the food reaches the stomach. [30] Taste: [31] Saliva acts as a solvent in which solid particles can dissolve and enter the taste buds through oral mucosa located on the tongue. These taste ...
Saliva, a liquid secreted by the salivary glands, contains salivary amylase, an enzyme which starts the digestion of starch in the food. [1] The saliva also contains mucus, which lubricates the food; the electrolyte hydrogencarbonate (HCO − 3), which provides the ideal conditions of pH for amylase to work; and other electrolytes (Na +, K ...
A sialogogue (also spelled sialagogue, ptysmagogue or ptyalagogue) is a substance, especially a medication, that increases the flow rate of saliva. [1] The definition focuses on substances that promote production or secretion of saliva (proximal causation) rather than any food that is mouthwatering (distal causation that triggers proximal causation).
