A half million people are diagnosed every year with oral cancer. While other cancers are more prevalent, oral cancer is among the most dangerous with only a fifty percent five-year survival rate.
A major reason for this low rate is because this fast growing cancer is difficult to detect early — diagnosis comes far too often after the disease has already well advanced. In an effort to detect cancer earlier many dentists visually screen for oral abnormalities during checkups, especially patients over fifty, tobacco or heavy alcohol users, patients with a family history of cancer or a medical history of exposure to the sexually transmitted human papilloma virus, HPV-16.
If they detect an abnormality, the dentist often refers the patient to an oral surgeon or other specialist for a possible biopsy. In this procedure the surgeon removes a sample of the abnormal tissue, which is then examined microscopically for cancer cells. A biopsy remains the most effective way to diagnose oral cancer.
Because of the disease's aggressive nature, many dentists lean to the side of caution when referring patients for biopsy. As a result 90% of oral biopsies reveal no cancer. Reducing the number of biopsy referrals is highly desirable, especially for the patient undergoing the procedure. Tissue samples tend to be large to ensure complete detection of any cancer cells. Depending on the size and location of the sample, there may be a risk for loss of function or disfigurement.
A new screening tool using a sample of a patient's saliva could help reduce the number of biopsy referrals. Besides DNA, saliva also contains dormant genes called biomarkers that activate in response to the presence of a specific disease. This particular saliva test identifies those biomarkers for oral cancer if they're present.
A sample with a low score of biomarkers indicates no cancer present (with a statistical confidence of 99%). A medium or high score indicates cancer may be present, but only a biopsy can determine for sure. Using this test, dentists might be able to reduce the number of biopsy referrals and instead be able to employ watchful waiting in certain cases. Because of its simplicity and non-invasiveness, saliva screening could help identify oral cancer earlier.
Everyone loves a concert where there's plenty of audience participation… until it starts to get out of hand.Â Recently, the platinum-selling band Fifth Harmony was playing to a packed house in Atlanta when things went awry for vocalist Camila Cabello. Fans were batting around a big plastic ball, and one unfortunate swing sent the ball hurtling toward the stage — and directly into Cabello's face. Pushing the microphone into her mouth, it left the “Worth It” singer with a chipped front tooth.
Ouch! Cabello finished the show nevertheless, and didn't seem too upset. “Atlanta… u wild… love u,” she tweeted later that night. “Gotta get it fixed now tho lol.” Fortunately, dentistry offers a number of ways to make that chipped tooth look as good as new.
A small chip at the edge of the tooth can sometimes be polished with dental instruments to remove the sharp edges. If it's a little bigger, a procedure called dental bonding may be recommended. Here, the missing part is filled in with a mixture of plastic resin and glass fillers, which are then cured (hardened) with a special light. The tooth-colored bonding material provides a tough, lifelike restoration that's hard to tell apart from your natural teeth. While bonding can be performed in just one office visit, the material can stain over time and may eventually need to be replaced.
Porcelain veneers are a more long-lasting solution. These wafer-thin coverings go over the entire front surface of the tooth, and can resolve a number of defects — including chips, discoloration, and even minor size or spacing irregularities. You can get a single veneer or have your whole smile redone, in shades ranging from a pearly luster to an ultra-bright white; that's why veneers are a favorite of Hollywood stars. Getting veneers is a procedure that takes several office visits, but the beautiful results can last for many years.
If a chip or crack extends into the inner part of a tooth, you'll probably need a crown (or cap) to restore the tooth's function and appearance. As long as the roots are healthy, the entire part of the tooth above the gum line can be replaced with a natural-looking restoration. You may also need a root canal to remove the damaged pulp material and prevent infection if the fracture went too far. While small chips or cracks aren't usually an emergency (unless accompanied by pain), damage to the tooth's pulp requires prompt attention.

Archeologists can tell us quite a bit about our primitive ancestors. For example, because of their coarse, abrasive diet and a primitive understanding of oral hygiene, their teeth had a rough go of it. They simply wore out faster — a contributing factor, no doubt, to their short life spans of thirty or forty years.
But thanks to improvements in lifestyle, healthcare and diet, people live much longer today. And so do their teeth, thanks to advances in dental care and disease prevention. While teeth still wear to some degree as we age, if we care for them properly with daily oral hygiene and regular dental visits, we can keep that wear to a minimum. Teeth truly can last a lifetime.
Unfortunately, it's still all too common for people to lose their teeth prematurely. The main reason: the two most prevalent dental diseases, tooth decay and periodontal (gum) disease. Tooth decay arises from high concentrations of mouth acid that erode enamel, teeth's irreplaceable protective shell. Gum disease is an infection that damages the bone supporting tissues as it infiltrates deep below the visible gum line.
While they occur by different mechanisms, the two diseases have some commonalities. They both, of course, can lead to tooth loss. And, they're both triggered by oral bacteria found in dental plaque, a thin film of food particles built up on tooth and gum surfaces. Multiplying bacteria feed on plaque and produce acid as a by-product. And certain bacterial strains infect gum tissues.
Both of these diseases can be treated successfully, especially if detected early. But the better approach is to prevent them in the first place. This introduces another commonality — they share the same prevention strategy of daily, comprehensive brushing and flossing for plaque removal, regular dental cleanings and checkups, and a sharp eye for any signs of disease like bleeding gums or tooth pain.
With diligent dental care and close attention to your oral health, you increase your chances of avoiding the full threat of these diseases.Â And with healthy teeth, you have a better chance of living a long and healthy life.

Magician Michael Grandinetti mystifies and astonishes audiences with his sleight of hand and mastery of illusion. But when he initially steps onto the stage, it’s his smile that grabs the attention. “The first thing… that an audience notices is your smile; it’s what really connects you as a person to them,” Michael told an interviewer.
He attributes his audience-pleasing smile to several years of orthodontic treatment as a teenager to straighten misaligned teeth, plus a lifetime of good oral care. “I’m so thankful that I did it,” he said about wearing orthodontic braces. “It was so beneficial. And… looking at the path I’ve chosen, it was life-changing.”
Orthodontics — the dental subspecialty focused on treating malocclusions (literally “bad bites”) — can indeed make life-changing improvements. Properly positioned teeth are integral to the aesthetics of any smile, and a smile that’s pleasing to look at boosts confidence and self-esteem and makes a terrific first impression. Studies have even linked having an attractive smile with greater professional success.
There can also be functional benefits such as improved biting/chewing and speech, and reduced strain on jaw muscles and joints. Additionally, well-aligned teeth are easier to clean and less likely to trap food particles that can lead to decay.
The Science Behind the Magic
There are more options than ever for correcting bites, but all capitalize on the fact that teeth are suspended in individual jawbone sockets by elastic periodontal ligaments that enable them to move. Orthodontic appliances (commonly called braces or clear aligners) place light, controlled forces on teeth in a calculated fashion to move them into their new desired alignment.
The “gold standard” in orthodontic treatment remains the orthodontic band for posterior (back) teeth and the bonded bracket for front teeth. Thin, flexible wires threaded through the brackets create the light forces needed for repositioning. Traditionally the brackets have been made of metal, but for those concerned about the aesthetics, they can also be made out of a clear material. Lingual braces, which are bonded to the back of teeth instead of the front, are another less visible option. The most discrete appliance is the removable clear aligner, which consists of a progression of custom-made clear trays that reposition teeth incrementally.
How’s that for a disappearing act?!

Energy drink makers would have you believe their products are a healthy rehydration choice for athletes while also giving them keener focus and renewed vitality. But before adding them to your sports regimen, you should also consider what effect these beverages could have on your teeth.
Energy drinks are similar in ingredients to sports drinks like Gatorade® and PowerAde®, which mostly consist of water, salts, vitamins, sugars and acids. In addition, energy drinks like Red Bull® and Monster Energy® add caffeine to boost energy.
Besides their sugar content, the main threat from a dental health perspective for both of these drinks is their acidity, which can severely erode tooth enamel. The irreplaceable loss of enamel significantly increases your risk of tooth decay and eventually tooth loss.
The threat of enamel erosion is especially pronounced whenever the mouth’s pH level falls below 5.5. The acidity of both sports and energy drinks falls well below this mark. In one experimental study samples of enamel exposed to a number of sports drinks lost an average of 1.5% of mineral content over five days; energy drinks more than doubled that loss at 3.1%.
Given the potential harm these beverages, especially energy drinks, can cause your teeth, you should exercise caution when consuming them. In fact, our best advice is for you to avoid energy drinks altogether, for your overall health as well as your teeth’s sake.
Unless you’re participating in a physically intense sport, water is your best source for hydration after exertion. Â If you do drink sports beverages, try to limit them to meal times when your saliva is most active to neutralize mouth acid. You can also rinse out your mouth with water after drinking to help further reduce mouth acidity.
As an athlete, you’ve trained your body to be at its optimum physical peak. Don’t let energy or sports drinks take the edge off your health, especially your teeth.
