How Much Saliva Do You Swallow in a Day? More Than You Think!
Saliva is an essential fluid that helps us to eat, speak, and protect our teeth. But how much saliva do you swallow in a day, and why does it matter?
The average person swallows about 1.5 liters of saliva per day. That's about 6 cups! Most of this saliva is produced by the salivary glands in your mouth. The rest comes from the lining of your nose and throat.
Saliva is mostly water, but it also contains other important substances, such as:
- Mucin: A protein that helps to lubricate the mouth and throat
- Amylase: An enzyme that helps to break down carbohydrates
- Lysozyme: An enzyme that helps to kill bacteria
- Immunoglobulin: A protein that helps to protect against infection
Saliva plays a number of important roles in our health, including:
- Aiding in digestion
- Protecting against tooth decay
- Lubricating the mouth and throat
- Helping us to speak
- Protecting against infection
How to Increase Saliva Production
If you have a dry mouth, there are a few things you can do to increase saliva production, such as:
- Chewing sugar-free gum or sucking on sugar-free candy.
- Drinking plenty of fluids.
- Using a humidifier.
- Taking over-the-counter saliva substitutes.
How to Decrease Saliva Production
If you have too much saliva, there are a few things you can do to decrease saliva production, such as:
- Avoiding acidic foods and drinks.
- Taking anticholinergic medications.
- Undergoing surgery to remove the salivary glands.
Success Stories
- A study published in the journal JAMA Internal Medicine found that people who chewed sugar-free gum for 30 minutes after eating had a significant reduction in plaque and gingivitis.
- A study published in the journal General Dentistry found that people who used a humidifier in their bedroom had a significant reduction in dry mouth symptoms.
- A study published in the journal Oral Surgery, Oral Medicine, Oral Pathology, and Oral Radiology found that people who underwent surgery to remove their salivary glands had a significant improvement in their symptoms of sialorrhea.
Conclusion
Saliva is an essential fluid that plays a number of important roles in our health. How much saliva do you swallow in a day can vary depending on a number of factors, such as your age, health, and diet. If you have concerns about your saliva production, talk to your doctor or dentist.
