FacialNervePainCanbeControlled

Every year 150,000 people, mostly women over age 50, find out they have a painful condition called trigeminal neuralgia. For many it begins as an occasional twinge along the face that steadily worsens until the simple act of chewing or speaking, or even a light touch, sets off excruciating pain.

The source of the pain is the pair of trigeminal nerves that course along each side of the face. Each nerve has three separate branches that provide sensation to the upper, middle and lower areas of the face and jaw.

The problem arises when areas of the myelin sheath, a fatty, insulating covering on nerves, becomes damaged, often because of an artery or vein pressing against it. As a result, the nerve can become hypersensitive to stimuli and transmit pain at even the slightest trigger. It may also fail to stop transmitting even after the stimulation that caused it is over.

Although the condition may not always be curable, there are various ways to effectively manage it. The most conservative way is with medications that block the nerve from transmitting pain signals to the brain, coupled with drugs that help stabilize the nerve and decrease abnormal firing.

If medication isn't enough to relieve symptoms, there may be some benefit from more invasive treatments. One technique is to insert a thin needle into the nerve to selectively damage nerve fibers to prevent them from firing. Another microsurgical procedure attempts to relocate the nerve away from a blood vessel that may be compressing it.

The latter procedure has some higher risks such as facial numbness or decreased hearing, and is often better suited for younger patients. Older patients may benefit more from the needle insertion procedure previously mentioned or a directed beam of high-dose radiation to alter the nerve.

To learn the best options for you, you should first undergo a neurological exam to verify you have trigeminal neuralgia and to rule out other causes. From there, you and your doctor can decide the best course of treatment for your age and individual condition.

Trigeminal neuralgia can be an unpleasant experience. But there are tried and true ways to minimize its effect on your life.

ConcerningYourOralHealthVapingIsntaSafeAlternativetoSmoking

The first week of April is National Public Health Week, putting the spotlight on health issues that impact us all. The popular practice of vaping is one of those top issues this year due to its connection with recent lung illnesses and deaths. But this isn't a new problem—dentists have been critics of vaping for some time now over the growing evidence of its effect on oral health.

Vaping is the popular term for inhaling aerosol vapors through an e-cigarette (or e-cig for short). The electronic device contains a small reservoir filled with flavored liquids that contain nicotine and other chemicals. The device heats the liquid, turning it into a vapor that's inhaled or “vaped” into the lungs.

Vaping has been touted by proponents as a safer alternative to cigarette smoking. But there's growing evidence that vaping isn't a kinder and gentler way to “smoke.” A good portion of that evidence comes from dentists who routinely treat oral problems caused or worsened by vaping.

In reality, the adverse effects of vaping on oral health aren't much different from smoking. Like smoking, vaping ingredients can irritate the inside of the mouth and cause dryness, an ideal environment for dental disease. And nicotine, the main chemical in both vaping and smoking, constricts blood vessels that deliver nutrients and disease-fighting antigens to the gums and teeth.

If these hazards weren't bad enough, recent clinical findings seem to indicate they're only the tip of the iceberg. Researchers from New York University's (NYU) College of Dentistry have found evidence from a combined study of cigarette smokers, e-cig users and non-smokers that vaping may significantly alter the mouth's microbiome to the ultimate detriment of oral health.

A “microbiome” is a term describing the intricate relationship between the millions of microorganisms inhabiting the human body and the body itself. While a few are malicious, many, namely in the gut and mouth, help the body obtain nutrients from food and fight against disease. Disrupting that delicate balance opens the door to diminished health.

The NYU researchers found that both smokers and e-cig users had higher levels of pathogenic bacteria in their saliva than non-smokers, suggesting both habits disrupted the mouth's microbiome balance enough to allow less benevolent bacteria to flourish. They also found that both smokers and e-cig users had significantly higher incidences of gum disease (72.5% and 42.5%, respectively) than non-smokers (28.2%).

If you're a smoker, a cessation program to quit the habit—not switching to vaping—is the way to a healthier life.

ViggoMortensensRed-CarpetSmile

The Golden Globes ceremony is a night when Hollywood stars shine their brightest. At the recent red-carpet event, leading man Viggo Mortensen had plenty to smile about: Green Book, the movie in which he co-starred, picked up the award for Best Motion Picture—Musical or Comedy. But fans looking at the veteran actor's big smile today might not realize that it once looked very different. A few years ago, an accident during the filming of The Two Towers took a major chip out of Mortensen's front tooth!

That might be OK for some movies (think The Hangover or Dumb and Dumber)—but it's not so great for everyday life. Fortunately, Mortensen visited a dentist promptly, and now his smile is picture-perfect. How was that accomplished? He didn't say…but generally, the best treatment for a chipped tooth depends on how much of the tooth's structure is missing.

If the tooth has only a small chip or crack, it's often possible to restore it via cosmetic bonding. This procedure can be done right in the dental office, frequently in a single visit. Here's how it works: First the tooth is cleaned and prepared, and then a tooth-colored resin is applied to the area being restored. After it is cured (hardened) with a special light, additional layers may be applied to build up the missing structure. When properly cared for, a tooth restored this way can look good for several years.

For a longer-lasting restoration, veneers may be recommended. These are wafer-thin shells made of durable material (most often porcelain) that cover the front (visible) surfaces of teeth. Strong and lifelike, veneers can match the exact color of your natural teeth—or give you the bright, high-wattage smile you've always wanted. No wonder they're so popular in Hollywood! Because veneers are custom-made for you, getting them may require several office visits.

If a chip or crack extends to the inner pulp of the tooth, a root canal procedure will be needed to keep the tooth from becoming infected—a situation that could have serious consequences. But you shouldn't fear a root canal! The procedure generally causes no more discomfort than filling a cavity (though it takes a little longer), and it can help save teeth that would otherwise be lost. After a root canal, a crown (cap) is generally needed to restore the visible part of the tooth.

When a damaged tooth can't be restored, it needs to be extracted (removed) and replaced. Today's best option for tooth replacement is a dental implant—a small, screw-shaped post inserted into the bone of your jaw that anchors a lifelike, fully functional crown. Implants require very little special care and can look great for many years, making them a top choice for tooth replacement
