Our nerves serve a vital purpose, alerting us to bodily discomfort, injury or disease — we couldn’t remain in good health for long without them. But when they malfunction due to genetics or disease, they can themselves become a source of pain and discomfort.
One such nerve disorder that affects the face is known as trigeminal neuralgia (TN) or tic douloureaux (from the French for “painful”). The nerves in question are the trigeminal, a pair that travel up from the brain stem through the skull into each side of the face where they each branch into the upper, middle and lower parts of the face and jaw. The pain can radiate from one or more of these branches.
TN is characterized by recurring episodes of brief but severe pain with accompanying muscle spasms. It may begin as a short twinge recurring over weeks, months or years before becoming increasingly painful. The slightest actions can trigger a painful episode: chewing, speaking, shaving or even the wind blowing on your face.
While it may be hard to determine its exact cause, it often seems to result from an artery or vein pressing on the nerve, causing it to signal pain at the slightest stimulation and then failing to stop transmitting when the stimulation is removed. It’s also associated with other inflammatory disorders like multiple sclerosis where the protective insulation around a nerve is damaged.
Before receiving treatment you should undergo a complete examination to rule out any other facial pain causes like temporomandibular (jaw joint) disorders or a dental abscess. You may also need to undergo a neurological examination and possible MRI imaging to pinpoint the exact cause, like a tumor or blood vessel pressing on the nerve.
Although the condition may not be curable, there are several effective management treatments. The more conservative approaches usually involve medications to block the nerve’s pain signals or decrease its abnormal firing. If this isn’t sufficient to diminish symptoms, there are surgical options: passing a thin needle through the nerve to selectively prevent fibers from firing, or moving aside a blood vessel pressing on it. High-dose targeted radiation may also be effective, especially with older patients.
The best treatment approach will depend on the exact cause, your age and overall health. Whatever the approach, you can gain significant relief from the pain of TN.
While many people still consider dental implants the "new kids on the block" in dental restoration, they're now in their fourth decade of use. And since their inception implant technology has continued to improve and revolutionize how we replace missing teeth.
Implants are a different "species" compared to other restoration methods. To be precise, an implant is a tooth root replacement—usually a titanium metal post imbedded directly into the jaw bone. Titanium is not only a biocompatible metal, but bone cells naturally grow on its surface to create a strong and durable hold. It's this secure hold that's most responsible for implants' high long-term success rate.
But we should also credit some of this success to the steady stream of advances over the years in implant construction and supporting technologies. For one thing, we're now more accurate and precise with implant placement thanks to advances in computer tomography (CT) and cone beam CT (CBCT) scanning.
These digital processes merge a series of images taken by a special camera to form a three-dimensional model of the jaw. We can manipulate this model on a computer monitor to view it from different vantage points. It can help us locate and avoid anatomical structures like nerves and sinuses when determining where to place a future implant. CT and CBCT are especially useful when there's a concern about adequate available bone, a necessity for stable implants.
Technology has also improved how we create surgical guides, often used during implant surgery to obtain the most accurate results. Surgical guides are custom-made devices that fit over the teeth with the drilling locations for the implants marked on them. Recent advances in 3-D printing have made these guides even more accurate so that they fit more securely in the mouth. This greater stability increases their accuracy during the drilling sequence during surgery.
These and other advances are helping ensure every implant is a success story. The end result is both a functional restoration and a beautiful smile.

A "toothy grin" might be endearing, but not necessarily healthy. More of the teeth showing may mean your gums have pulled back or receded from the teeth. If so, it's not just your smile that suffers—the parts of teeth protected by the gums could become more susceptible to disease.
There are a number of causes for gum recession. Some people are more likely to experience it because of genetically thinner gum tissues. Over-aggressive brushing could also contribute to recession. But the most common cause by far is periodontal (gum) disease, a bacterial infection triggered by dental plaque accumulating on teeth mainly as a result of inadequate hygiene.
There are some things we can do to help heal and restore recessed gums, most importantly treating gum disease. The number one goal of treatment is to uncover and remove all dental plaque from tooth and gum surfaces, which can take several sessions and sometimes minor surgery if the infection has reached the tooth roots. But removing plaque and tartar (calcified plaque) is necessary to stop the infection and allow the gums to heal.
For mild recession, this may be enough for the gums to regain normal coverage. But in more severe cases we may need to help rejuvenate new tissue with grafting surgery. In these highly meticulous procedures a surgeon uses microscopic techniques to position and attach donated tissue to the recession site. The graft serves as a scaffold on which new tissue growth can occur.
While these treatments can be effective for reversing gum recession, they often require time, skill and expense. It's much better to try to prevent gum recession—and gum disease—in the first place. Prevention begins with daily brushing and flossing to prevent plaque buildup, as well as regular dental visits for more thorough cleanings. Be on the lookout too for any signs of a beginning gum infection like swollen, reddened or bleeding gums and see your dentist as soon as possible to minimize any damage to your gums.
Caring for your gums is equally as important as caring for your teeth. Healthy gums equal a healthy mouth—and an attractive smile.
