What is the Importance of Saliva?

Saliva isn’t something you probably spend much time thinking about. But did you know that at every moment of every day, your saliva is affecting your health? Saliva is vital for a healthy mouth, good digestion, and more. Read on to learn how saliva does a mouth good.

What is saliva and how is it made?

Saliva is a liquid made of water, mucus, proteins, minerals, and an enzyme called amylase. It’s made by the salivary glands, many small organs around the cheeks, lips, tongue, and other parts of the mouth. There are six major salivary glands and hundreds of minor ones. Saliva moves through tiny tubes called ducts that carry the saliva from the glands into your mouth. Small amounts of saliva are sent into the mouth constantly, to keep the mouth moist. Normally, the body makes up to two to four pints of saliva a day. But the salivary glands really kick into action when you eat, or even just think about or smell food. Then your glands make lots of saliva, and you can notice much more of it in your mouth.

How does saliva help your health?

Saliva does lots of helpful things. Research has shown that it helps protect against gum disease and tooth decay. Your teeth are covered with a thin film of saliva that helps defend against bacteria. There are antimicrobial agents in saliva that help kill bacteria. As saliva moves around the mouth, it helps sweep away small bits of food that could have caused tooth decay. Saliva also carries minerals that help rebuild the enamel surfaces of teeth. It can help neutralize acids in the mouth during and after eating that break down tooth enamel.  Saliva plays a part in digesting food too. The enzyme amylase found in it helps starches start to break down in your mouth and it helps you swallow food by making it wet and soft so it can slide down your throat more easily.

Is it possible to not have enough saliva?

Some people don’t make enough saliva. This is called dry mouth, which is also known as xerostomia. Dry mouth causes the gums, tongue, and other tissues in the mouth to become swollen and uncomfortable. Germs thrive in this type of setting. Certain health conditions, such as Sjögren’s syndrome and diabetes, can cause dry mouth. Cancer treatments can also cause it and so do many medications, such as those for allergies, high blood pressure, depression, and more. When you don’t have enough saliva, oral problems are more likely. Gum disease and tooth decay can happen much more easily. You can have more infections from bacteria, yeast, and fungus. You can also have trouble swallowing and digesting food. Plus, you’ll have the uncomfortable feeling of a dry mouth. If you have a dry mouth:

  • Make sure you drink plenty of water every day. Dehydration can make you create less saliva.
  • Talk with your health care provider to see if you’re taking a medication that causes dry mouth.
  • Chew sugar-free gum and suck on sugar-free candy or mints. This can help you produce more saliva.
  • Keep up good dental care by brushing and flossing every day. Ask your dentist if a prescription strength fluoride toothpaste or fluoride rinse would be helpful for you.
  • See your dentist regularly for checkups and cleanings. He or she can help prevent problems and spot them early.
  • See your health care provider if you have white patches or sore spots in your mouth.
  • Ask your health care provider about artificial saliva. He or she can prescribe a rinse or spray to help keep your mouth moist.
  • Avoid foods that are salty, spicy, or acidic — these can dry and irritate your mouth. You may also want to avoid drinking alcohol, which can also dry your mouth. Choose soft and smooth foods, and make foods moist with sauces or broth.
  • Rinse 4-6 times a day with a baking soda solution to reduce bacterial acids that cause cavities. You can make it at home from 2 teaspoons of baking soda in 8 ounces of water.

If you’re having any issues with saliva production, suspect that you consistently have bad breath, or constantly suffer from a dry mouth, it’s a great idea to talk to your dentist and doctor to find the culprit and determine a solution together. Saliva is critical to your mouth’s overall health, and it’s important to identify the problem early.
