Saliva, saliva, iler, in medical terms known as saliva. Saliva is a clear liquid produced by salivary glands, a small organ on the inside of each side of the cheek, at the bottom of the tongue, and under the jaw at the very front of the mouth. Salivary glands produce saliva about 2 to 4 liters per day.

Although the name is water, saliva is not only made of water but also contains mucus, protein, minerals, and an enzyme called amylase. the function of saliva is:

1. Helps digestion process of food
Saliva glands produce saliva to wet and dissolve food, making it easier to digest. Before food enters the stomach, saliva breaks down the food with the help of amylase enzymes that help starch break in the mouth. The function of saliva also helps you swallow food by making it wet and soft so that it can slide into your throat more easily.

2. Cleanse and protect the mouth
Saliva can clean the inside of the mouth, and rinse teeth to keep them clean. Enzymes in saliva also help fight infections in the mouth.

3. Prevent damage to teeth and gums
A study has shown that saliva can help protect against gum disease and tooth decay. Your teeth are covered with a thin layer of saliva which helps defend against bacteria. There are antimicrobial agents in saliva that help kill bacteria.

The function of saliva lining each tooth helps to shed the remaining food that is stuck and can cause tooth decay. Saliva also carries minerals that help rebuild the surface of enamel teeth. Saliva can also help neutralize acid in the mouth during and after eating which breaks down tooth enamel.

4. Prevent dry mouth
The function of saliva can prevent the occurrence of dry mouth. As we age, we also produce less saliva. This causes dry mouth, or xerostomia. Therefore, to produce saliva, you can chew sugarless gum, eat something, or drink water.
