Temporomandibular joint disorder (TMD) is an umbrella term for a number of chronic jaw problems. These conditions cause recurring pain for 10 to 30 million Americans, especially women of childbearing age.
But even after decades of treatment and research, a full understanding of TMD's underlying causes eludes us. That doesn't mean, however, that we haven't made progress—we have indeed amassed a good deal of knowledge and experience with TMD and how best to treat it.
A recent survey of over a thousand TMD patients helps highlight the current state of affairs about what we know regarding these disorders, and where the future may lie in treatment advances. Here are a few important findings gleaned from that survey.
Possible causes. When asked what they thought triggered their TMD episodes, the top answers from respondents were trauma, stress and teeth clenching habits. This fits in with the consensus among experts, who also include genetic disposition and environmental factors. Most believe that although we haven't pinpointed exact causes, we are over the target.
Links to other disorders. Two-thirds of survey respondents also reported suffering from three or more other pain-related conditions, including fibromyalgia, rheumatoid arthritis and chronic headaches. These responses seem to point to possible links between TMD and other pain-related disorders. If this is so, it could spur developments in better diagnostic methods and treatment.
The case against surgery. Surgical procedures have been used in recent years to treat TMD. But in the survey, of those who have undergone surgery only one-third reported any significant relief. In fact, 46% considered themselves worse off. Most providers still recommend a physical joint therapy approach first for TMD: moist heat or ice, massage and exercises and medications to control muscle spasms and pain.
These findings underscore one other important factor—there is no “one size fits all” approach to TMD management. As an individual patient, a custom-developed action plan of therapy, medication, and lifestyle and diet practices is the best way currently to reduce the effects of TMD on your life.

The mouth is a crowded place with nerves, blood vessels and sinus cavities sharing common space with the teeth and gums. Although important in their own right, these structures can also hinder treatment for complex dental situations like dental implant surgery or impacted teeth.
Treating these and similar situations depends on getting an accurate depiction of “what lies beneath.” Conventional x-rays help, but their two-dimensional images don't always give the full picture. There's another way—cone beam computed tomography (CBCT).
Similar to CT scanning, CBCT uses x-ray energy to take hundreds of “sliced” images that are then re-assembled with special software to create a three-dimensional model viewable on a computer screen. CBCT is different, though, in that it employs a scanning device that revolves around a patient's head, which emits a cone-shaped beam of x-rays to capture the images.
A dentist can manipulate the resulting 3-D model on screen to study revealed oral structures from various angles to pinpoint potential obstacles like nerves or blood vessels. The detailed model may also aid in uncovering the underlying causes of a jaw joint disorder or sleep apnea.
CT technology isn't the only advanced imaging system used in healthcare. Another is magnetic resonance imaging (MRI), which excites hydrogen atoms in water molecules. This produces different vibration rates in individual tissue structures, which are then translated into detailed images of these structures. Unlike CT or CBCT, MRI doesn't use x-ray energy, but rather a magnetic field and radio waves to produce the atomic vibrations.
But while providing good detail of soft tissues, MRI imaging doesn't perform as well as CBCT with harder tissues like bone or teeth. As to the potential risks of CBCT involving x-ray radiation exposure, dentists follow much the same safety protocols as they do with conventional x-rays. As such, they utilize CBCT only when the benefits far outweigh the potential x-ray exposure risks.
And, CBCT won't be replacing conventional x-rays any time soon—the older technology is often the more practical diagnostic tool for less invasive dental situations. But when a situation requires the most detailed and comprehensive image possible, CBCT can make a big difference.

If you think your smile is beyond hope, you might be in for a happy surprise: Today's dental cosmetics can improve even the most forlorn dental situation. It could be a one-visit tooth whitening—or a total “smile makeover.”
If it's the latter, your transformation journey could take months or even years—so you need some idea of where this journey will take you. That will come through initial discussions with your dentist about your dreams and desires for a new smile.
But you'll also need to consider what your dental condition will practically allow: Although your goal is a more attractive appearance, the higher priority is your long-term dental health. There's also cost—dental enhancements can be expensive, so you may have to adjust your dream smile to match the reality of your finances.
With the big picture in focus, the next step is to refine the details of your makeover plan. Nothing does this better—for you and your dentist—than to “see” your proposed smile ahead of time. This is possible with computer technology: Your dentist can modify a digitized photo of your face and smile to show the proposed changes to your teeth and give you a reasonable view of your future smile.
Another way is to create a “trial smile.” Using composite dental material, your dentist fashions a temporary restoration that fits over your teeth. Unlike the digitally enhanced still photo, a trial smile let's you see what your new appearance will look like while moving, talking or smiling. Although it's removed before you leave the office, you can have photos taken to show friends and family.
You and your dentist can use these methods to make adjustments to your makeover plan before applying the real enhancements. It also eliminates any unpleasant surprises after all the work is done—you'll already know what your future smile will look like.
These initial steps are just as important as the actual procedures you'll undergo. Through careful planning, you'll gain a new smile that can improve your life.
