Why do we have saliva in our mouths?

Dr. James Wright
Dentistry 33 years experience
Many reasons: Saliva keeps your mouth moist, helps tongue function & starts the digestion process with an enzyme called amylase. Saliva antibodies & proteins are helpful in reducing dental bacteria & bacterial infections & also acts as a buffering agent which helps protect against the acid which would otherwise damage tooth enamel and lead to decay and tooth loss.

Saliva differences: It's very simple real saliva is produced by salivary glands throughout the oral cavity. Artificial saliva is a substitute that is produced that is used when the body can't produce saliva. Usually this happens do to side effects to certain medications, patients undergoing radiation treatments, certain autoimmune diseases to name a few causes. There are a variety of products to aid as substitutes.

A 27-year-old female asked:

What does a saliva pH of 5 indicate? I'm 27 and otherwise healthy.

Acidic!: Saliva ph of 5 is quite low! that means your saliva is quite acidic. Makes me wonder if you didn't have it checked right after drinking a can of pop or a cup of coffee or something along those lines.
