Humans have countless salivary glands, which extend from the cheeks to the floor of the mouth and down to the lower jaw. Every day, they produce around 1.5 litres of saliva, release it and make our lives easier.
On the one hand, saliva makes the chyme more slippery, which makes it easier to swallow food. The enzymes, proteins and antibodies contained in saliva ward off the first unwelcome intruders in the mouth. Saliva also provides natural protection for the teeth. The ions it contains, such as sodium, calcium and fluoride, keep bacteria away from the teeth. Saliva also washes away and swallows fungi, viruses and food residues, which has a cleansing effect.
Saliva also helps us with seemingly mundane functions such as speaking, tasting and swallowing. Its importance is particularly noticeable to those who have struggled with dry mouth for a long time.
