SalivaisaKeyIngredientinOralHealth

When you think of saliva, the word “amazing” probably doesn’t come to mind. But your life and health would be vastly different without this “wonder” fluid at work in your mouth.

Saliva originates from a number of glands located throughout the mouth. The largest are a pair known as the parotids, located just under the ears on either side of the lower jaw, which produce a thin and watery liquid. The sublingual glands under the tongue produce thicker saliva with a mucous secretion; the saliva from the submandibular glands located under the lower jaw has a consistency somewhere between that of the parotids and the sublingual glands. All these different consistencies of saliva combine to produce a fluid rich in proteins, enzymes, minerals and antibodies.

Saliva performs at least five basic functions in the mouth. First, it washes away food particles after eating and reduces the amount of sugar available for decay-causing bacteria to consume. It protects and disinfects the mouth with antibodies, proteins and enzymes that fight against and help prevent the growth of bacteria. Saliva neutralizes high acidity levels in the mouth, necessary to prevent enamel erosion from acid; and when enamel has softened due to acidity (de-mineralization), the calcium and other minerals in saliva help restore some of the enamel’s lost minerals (re-mineralization). Saliva also aids in digestion by lubricating the mouth and helping the body break down starches in food with its enzymes.

In recent years, scientists have also gained insight into another property of saliva that promises better disease diagnosis in the future. Like blood and urine, saliva contains biological markers for disease. As more diagnostic machines calibrated to these specific markers are developed and used, it could signal a more effective way to identify conditions from saliva samples that are easier to collect than other bodily fluids.

Its less than glamorous image aside, your mouth would be quite a different (and unhealthy) place without saliva. And, developments in diagnostics could make this unsung fluid even more valuable in maintaining your health.

BracesAreNoHurdleforOlympicTrackStar

Lashinda Demus holds the U.S record in the 400 meter hurdles, with a time of 52.47 seconds, the third fastest ever recorded. While her twin 5-year-old boys cheered her on, she brought home a silver medal from the 2012 London Olympics. But when it comes to her full set of upper and lower braces, there's no silver to be seen!

Demus is a top-ranked competitor, a wife and a mom — and an adult who is currently in orthodontic treatment. With her orthodontist's approval, she chose clear ceramic braces. These are just one of the treatment options available to adult patients, many of whom prefer a less noticeable style of orthodontic appliance.

As many as three-quarters of adults are thought to have some form of orthodontic problem. Common issues include teeth that are crowded too closely together, or ones that have drifted too far apart after an extraction or other tooth loss. It is believed that straightened teeth are easier to clean and better for chewing — they can also improve an adult's social life, and even his or her career prospects!

Some grown-ups may hesitate to consider orthodontic treatment because they remember the “railroad tracks” they saw in junior high school. In fact, there have been many changes in orthodontic appliances in the past few years. Two popular choices for adults are colorless braces (the kind Demus wears) and clear orthodontic aligners.

Colorless ceramic braces are made of high-tech composite materials. They resist staining, and are less noticeable because their translucent appearance blends with the teeth. Often, a single wire is the only part that's plainly visible. Sometimes it's even possible to place them on the lingual (tongue) side of the teeth.

Clear aligners are an alternative to braces that are available to adults and teens. Instead of wires and attachments, these consist of a series of transparent, removable trays that are placed over the teeth and worn 20 hours per day. Over a period of six months to two years, the teeth are gradually straightened as you progress from one computer-designed tray to the next. Best of all, you can remove the trays completely to clean your teeth, and for important occasions.

Which one is right for you? It depends. While aligners have been successful in treating mild to moderate spacing issues, more difficult problems with the bite may require a more traditional form of braces. Also, there are a few health problems which might need to be attended to before orthodontic treatment is begun. The best way to learn about your options is to come in for a consultation. But remember: if you want a better smile, it's never too late.
