For over a century now, health providers have depended on blood and urine samples to diagnose many forms of disease. Very soon, though, we may routinely use a different bodily fluid that's easier and cheaper to collect: saliva.
Secreted by six hundred or more glands in the mouth, saliva performs a number of important functions for digestion and overall oral health. Saliva lubricates the mouth to make food easier to swallow. Its enzymes begin the digestion process breaking down food even before we swallow. It also helps wash out food particles that could build up as plaque on the teeth and harbor disease-causing bacteria.
In terms of dental health, its greatest role is as a neutralizer of food acid. It's natural after we eat for the acid levels in the mouth to rise above normal. If acid remains in contact with enamel for an extended period of time it can soften the enamel's minerals and make it easier for them to erode. Within thirty minutes to an hour after eating, saliva neutralizes acid and restores the mouth's normal pH level. Saliva also contains calcium and phosphate materials, which helps restore some of the minerals the enamel may have lost from the acid contact.
But we're discovering saliva can do even more: we can now use it as an indicator for certain conditions in the body. Like blood or urine, saliva contains molecules that can serve as biological markers for different types of disease. By employing devices calibrated to detect these markers, we can use saliva to uncover cancer, diabetes or other systemic conditions.
As these particular devices are manufactured and become more available, the use of saliva for disease diagnosis will rise. In the future, you may not need a trip to the bathroom or wince at a needle stick — a swab of your saliva will do!

Chicken pox is a common viral infection that usually occurs during childhood. Although the disease symptoms only last a short time, the virus that caused it may remain, lying dormant for years within the body's nervous system. Decades later it may reappear with a vengeance in a form known as herpes zoster, what most people know as shingles.
A shingles outbreak can be quite painful and uncomfortable—and it's also not a condition to take lightly. Occurring mainly in people over fifty, it often begins with an itching or burning sensation in the skin. This is often followed by a red rash breaking out in a belt-like pattern over various parts of the body, which may later develop into crusty sores. Symptoms may vary from person to person, but people commonly experience severe pain, fever and fatigue.
Besides the general discomfort it creates, shingles can also pose major health problems for certain people. Individuals with other health issues like pregnancy, cancer or a compromised immune system may experience serious complications related to a shingles outbreak.
In its early stages, shingles is contagious, spreading through direct contact with shingles sores or lesions or through breathing in the secretions from an infected person. This characteristic of shingles could affect your dental care: because the virus could potentially pass to staff and other patients, dentists usually postpone cleanings or other dental treatments for patients with shingles, particularly if they have a facial rash.
If you're diagnosed with shingles, most physicians recommend you begin antiviral treatment as soon as possible. You should also let your dentist know if you have shingles, which may put off any scheduled treatments until your doctor determines you're no longer contagious.
There's one other thing you can do, especially if you're over 60: obtain a shingles vaccine, available from most physicians or clinics. The vaccine has proven effective in preventing the disease, and could help you avoid this most unpleasant health experience.
Via a recent Instagram post, pop diva Ariana Grande became the latest young celebrity to publicly acknowledge a dental milestone: having her wisdom teeth removed. The singer of hits such as “Break Free” and “Problem” posted an after-surgery picture of herself (wearing her signature cat-eye eyeliner), with a caption addressed to her teeth: “Peace out, final three wisdom teeth. It’s been real.”
With the post, Grande joined several other celebs (including Lily Allen, Paris Hilton and Emile Hirsch) who have shared their dental surgery experience with fans. Will "wisdom teeth removal" become a new trending topic on social media? We aren’t sure — but we can explain a bit about the procedure, and why many younger adults may need it.
Technically called the “third molars,” wisdom teeth usually begin to emerge from the gums between the ages of 17 and 25 — presumably, around the same time that a certain amount of wisdom emerges. Most people have four of these big molars, which are located all the way in the back of the mouth, on the left and right sides of the upper and lower jaws.
But when wisdom teeth begin to appear, there’s often a problem: Many people don’t have enough space in their jaws to accommodate them. When these molars lack sufficient space to fully erupt (emerge), they are said to be “impacted.” Impacted teeth can cause a number of serious problems: These may include pain, an increased potential for bacterial infections, periodontal disease, and even the formation of cysts (pockets of infection below the gum line), which can eventually lead to tooth and bone loss.
In most cases, the best treatment for impacted wisdom teeth is extraction (removal) of the problem teeth. Wisdom tooth extraction is a routine, in-office procedure that is usually performed under local anesthesia or “conscious sedation,” a type of anesthesia where the patient remains conscious (able to breathe normally and respond to stimuli), but is free from any pain or distress. Anti-anxiety medications may also be given, especially for those who are apprehensive about dental procedures.
So if you find you need your wisdom teeth extracted, don’t be afraid to “Break Free” like Ariana Grande did; whether you post the results on social media is entirely up to you.
