While it doesn’t garner the star power of blood, saliva is still an important bodily fluid. A true multi-tasker, saliva contributes in many ways to the function and health of the body, from stronger teeth to more efficient digestion.
Here are six ways saliva helps your mouth and body function properly and stay healthy.
The mouth’s natural cleanser. Bacteria are responsible for much of the dental disease that plagues us, particularly tooth decay and gum disease. Saliva clears the mouth of food remnants, bacteria’s primary feeding source, after we eat. This leaves a cleaner mouth and fewer bacteria to cause infection.
The immune system’s partner. Saliva contains an antibody called Immunoglobulin A (IgA) that attacks disease-causing microorganisms. Along with secreting other antibacterial agents like lactoferrin and lyzozyme that curb the growth and development of bacteria, saliva serves as the body’s first line of defense against pathogens entering through the mouth.
Acid neutralizer. The optimal oral environment is a neutral pH of 7. Many of our foods and beverages, though, are highly acidic, which can raise the mouth’s acid level. The acidic environment causes the minerals in tooth enamel to soften and dissolve (a process called de-mineralization). Saliva restores the balance by neutralizing any remaining acid after we eat (a process that takes about 30 to 60 minutes).
Mineral replacer. Even under normal conditions, enamel will de-mineralize to some extent whenever the mouth becomes acidic. Saliva restores some of the enamel’s lost minerals like calcium and phosphate while it’s neutralizing acid. If fluoride is also present in saliva from fluoridated drinking water or toothpaste, it too is absorbed by the enamel making it stronger and more resistant to acid attacks.
Digestion enhancer. Saliva lubricates the mouth while we eat, making it easier for us to chew (and taste) our food. Saliva also releases the enzyme amylase as we chew to break down starches before the food enters our stomach. The end result is more efficient and comfortable digestion.
The wave of the future in diagnostics. Like blood and urine, saliva contains genetic and disease markers that could tell a physician if a patient has a certain condition. Since collecting a saliva sample is much easier than with these other bodily fluids, diagnosing disease with saliva will become more prevalent as more calibrated devices reach the market.

Is a chipped tooth big news? It is if you’re Justin Bieber. When the pop singer recently posted a picture from the dental office to his instagram account, it got over 2.6 million “likes.” The snapshot shows him reclining in the chair, making peace signs with his hands as he opens wide; meanwhile, his dentist is busy working on his smile. The caption reads: “I chipped my tooth.”
Bieber may have a few more social media followers than the average person, but his dental problem is not unique. Sports injuries, mishaps at home, playground accidents and auto collisions are among the more common causes of dental trauma.
Some dental problems need to be treated as soon as possible, while others can wait a few days. Do you know which is which? Here are some basic guidelines:
A tooth that’s knocked out needs attention right away. First, try and locate the missing tooth and gently clean it with water — but avoid holding the tooth’s roots. Next, grasp the crown of the tooth and place it back in the socket facing the correct way. If that isn’t possible, place it between the cheek and gum, in a plastic bag with the patient’s saliva or a special tooth preservative, or in a glass of cold milk. Then rush to the dental office or emergency room right away. For the best chance of saving the tooth, it should be treated within five minutes.
If a tooth is loosened or displaced (pushed sideways, deeper into or out of its socket), it’s best to seek dental treatment within 6 hours. A complete examination will be needed to find out exactly what’s wrong and how best to treat it. Loosened or displaced teeth may be splinted to give them stability while they heal. In some situations, a root canal may be necessary to save the tooth.
Broken or fractured (cracked) teeth should receive treatment within 12 hours. If the injury extends into the tooth’s inner pulp tissue, root canal treatment will be needed. Depending on the severity of the injury, the tooth may need a crown (cap) to restore its function and appearance. If pieces of the tooth have been recovered, bring them with you to the office.
Chipped teeth are among the most common dental injuries, and can generally be restored successfully. Minor chips or rough edges can be polished off with a dental instrument. Teeth with slightly larger chips can often be restored via cosmetic bonding with tooth-colored resins. When more of the tooth structure is missing, the best solution may be porcelain veneers or crowns. These procedures can generally be accomplished at a scheduled office visit. However, if the tooth is painful, sensitive to heat or cold or producing other symptoms, don’t wait for an appointment — seek help right away.
Justin Bieber earned lots of “likes” by sharing a picture from the dental office. But maybe the take-home from his post is this: If you have a dental injury, be sure to get treatment when it’s needed. The ability to restore a damaged smile is one of the best things about modern dentistry.

Dentures can be an effective and affordable solution for people who've lost all their teeth. With them a person can once again eat nutritiously, speak clearly and smile confidently — and with regular care they can last for years.
As part of that ongoing care, be sure you consider one important thing with your dentures: you may want to take them out at night while you sleep. If you do you'll lessen your chances of developing these 4 health problems.
Accelerated bone loss. Traditional dentures are fitted to rest securely on the gums. This, however, creates pressure on the gums and the bony ridges beneath them that can contribute to bone loss. Wearing dentures around the clock usually accelerates this process, which could eventually lead to among other problems looser denture fit and discomfort.
Bacterial and fungal growth. Microorganisms that cause oral diseases find conducive breeding spots on the underside of dentures while they're worn in the mouth. Studies have found that people who continuously wear their dentures are more likely to have bacterial plaque and oral yeast than those that don't.
Potentially dangerous infections. Bacterial and fungal growth increases your risk of oral infections that could affect more than your mouth. A recent study of elderly nursing home residents found those who wore their dentures during sleep were over twice as likely to develop serious cases of pneumonia requiring hospitalization. It's believed bacteria harbored on the dentures can pass from the mouth to the lungs as a person breathes over them while they sleep.
Blocked salivary flow. During the night our salivary flow naturally ebbs; wearing dentures while we sleep could cause denture stomatitis, in which the tissues covered by a denture (particularly along the roof of the mouth) become inflamed and infected with yeast. It's often accompanied by angular cheilitis or cracking at the corners of the mouth that becomes infected by the same yeast.
Wearing your dentures while you sleep contributes to conditions ranging from irritating to life-threatening. To prevent such problems clean your dentures as well as the rest of your mouth regularly — and talk to your dentist whether you should leave them out when you go to bed.
