Role of Saliva in a Healthy Mouth

Saliva is a clear fluid, mostly water, which is produced by the salivary glands. But it’s not just water. Saliva also contains electrolytes, white blood cells, mucous, enzymes, epithelial cells, and antimicrobial substances. Enzymes such as lysozyme and peroxidase are also found in saliva. These are antibacterial, which help kill bacteria throughout the mouth. Throughout the course of a day the salivary glands can produce up to 4 pints of saliva.

It helps to remove food from teeth as you chew and swallow. This protects your overall oral health. There are also proteins and minerals in saliva, both of which help to prevent gum disease and tooth decay. Saliva can also be a great indicator of your overall health.

Dry mouth can lead to bad breath, a metallic taste in the mouth, thrush in the mouth, and dental issues including cavities. If saliva is thick and stringy, your body may have trouble producing saliva.

Producing too much saliva can cause difficulty swallowing, eating, and even talking.
