If you're suffering from jaw pain or impaired function, it may not be the only source of chronic pain in your body. Of the millions of adults with temporomandibular joint disorders (TMD), many have also been diagnosed — among other conditions — with fibromyalgia, rheumatoid arthritis or sleep problems.
TMD is actually a group of painful disorders that affect the jaw joints, muscles and surrounding tissues. Besides pain, other symptoms include popping, clicking or grating sounds during jaw movement and a restricted range of motion for the lower jaw. Although we can't yet pinpoint a definite cause, TMD is closely associated with stress, grinding and clenching habits or injury.
It's not yet clear about the possible connections between TMD and other systemic conditions. But roughly two-thirds of those diagnosed with TMD also report three or more related health conditions. Debilitating pain and joint impairment seem to be the common thread among them all. The similarities warrant further research in hopes of new treatment options for each of them.
As for TMD, current treatment options break down into two basic categories: a traditional, conservative approach and a more interventional one. Of the first category, at least 90% of individuals find relief from treatments like thermal therapy (like alternating hot and cold compresses to the jaw), physical therapy, medication or mouth guards to reduce teeth clenching.
The alternative approach, surgery, seeks to correct problems with the jaw joints and supporting muscles. The results, however, have been mixed: in one recent survey a little more than a third of TMD patients who underwent surgery saw any improvement; what's more alarming, just under half believed their condition worsened after surgery.
With that in mind, most dentists recommend the first approach initially for TMD. Only if those therapies don't provide satisfactory relief or the case is extreme, would we then consider surgery. It's also advisable for you to seek a second opinion if you're presented with a surgical option.
Hopefully, further research into the connections between TMD and other inflammatory diseases may yield future therapies. The results could help you enjoy a more pain-free life as well as a healthy mouth.

Compared to other dental restorations—a few of which have been around for over a century—implants are a relatively recent development. But even though it's just now entering its fourth decade, recent advances have catapulted implant therapy well beyond where it began.
That's due mainly to digital technology. Two examples of this, computed tomography (CT) and 3-D printing, are increasing the accuracy and efficiency of implant placement.
Properly placing an implant is one of the most important elements in achieving a natural and attractive result. But finding the best location is often difficult due to a lack of suitable bone volume, the patient's bite or the proximity of anatomical structures like nerves and blood vessels. CT imaging, especially Cone Beam CT scanners (CBCT), is helping to make implant placement planning easier.
Unlike the static, two-dimensional views of standard x-rays, CBCT takes hundreds of images and digitally blends them together to create a virtual 3-D model of the patient's jaw and face. Dentists can view this highly detailed model on a computer monitor from various vantage points and better identify possible obstructions. With better information about what "lies beneath," they can more accurately pinpoint the best implant site.
Creating the ideal plan is one thing—successfully implementing it is another. Dentists often create a surgical guide that helps them drill in precisely the right positions during surgery. The guide, which resembles a mouthguard, fits over the gums and contains marker locations for drilling.
Many dentists are now using 3-D printing to create these surgical guides. A 3-D printer turns a digital model of the guide based on measurements of the patient's mouth and proposed implant locations into an actual physical object "printed out" layer by layer of special polymer material. The end product can be more precise than guides created by other means.
These and other technological developments are helping implant therapy rise to a new level of success. With the resulting increase in accuracy, efficiency and less treatment time, tomorrow's implant patients will be the ultimate beneficiaries.

Even with modern prevention and treatment advances, losing teeth in later life is still a sad but common part of human experience. Just as generations have before, many today rely on dentures to regain their lost dental function and smile.
But although effective, dentures have their weaknesses. The most serious: they can't prevent jawbone deterioration, a common problem associated with tooth loss.
Bone health depends on chewing forces applied to the teeth to stimulate replacement growth for older bone cells. When teeth are gone, so is this stimulation. Dentures can't replicate the stimulus and may even accelerate bone loss because they can irritate the bone under the gums as they rest upon them for support.
But there's a recent advance in denture technology that may help slow or even stop potential bone loss. The advance incorporates implants with dentures to create two hybrid alternatives that may be more secure and healthier for the supporting bone.
The first is known as an overdenture, a removable appliance similar to a traditional denture. But instead of deriving its support from the gums alone, the overdenture attaches to three to four implants (or only two, if on the lower jaw) that have been permanently set into the jawbone. This not only increases stability, but the implants made of bone-friendly titanium attract and foster increased bone growth around them. This can help slow or even stop the cycle of bone loss with missing teeth.
The second type is a fixed denture. In this version, four to six implants are implanted around the jaw arch. The denture is then secured in place to these implants with screws. It's a little more secure than the overdenture, but it's also more expensive and requires good quality bone at the implant sites.
If you've already experienced significant bone loss you may first need bone grafting to build up the implant sites for these options, or choose traditional dentures instead. But if you're a good candidate for an implant-supported denture, you may find it provides better support and less risk of continuing bone loss than traditional dentures.
