Generations have depended on dentures to effectively and affordably replace lost teeth. But they do have a major weakness: They contribute to jawbone loss that creates not only mouth and facial problems, but can also ruin a denture’s fit.
Bone loss is a normal consequence of losing teeth. The biting forces normally generated when we chew stimulate new bone to replace older bone. When a tooth is missing, however, so is that chewing stimulation. This can slow bone replacement growth and gradually decrease the density and volume of affected bone.
While dentures can restore dental appearance and function, they can’t restore this growth stimulation. What’s worse, the pressure of the dentures against the gum-covered jaw ridge they rest upon may irritate the underlying bone and accelerate loss.
But there is a solution to the problem of denture-related bone loss: an implant-supported denture. Rather than obtaining its major support from the gum ridges, this new type of denture is secured by strategically-placed implants that connect with it.
Besides the enhanced support they can provide to a denture restoration, implants can also deter bone loss. This is because of the special affinity bone cells have with an implant’s imbedded titanium post. The gradual growth of bone on and around the implant surface not only boosts the implant’s strength and durability, it can also improve bone health.
There are two types of implant-supported dentures. One is a removable appliance that connects with implants installed in the jaw (three or more for the upper jaw or as few as two in the lower). It may also be possible to retrofit existing dentures to connect with implants.
The other type is a fixed appliance a dentist permanently installs by screwing it into anywhere from four and six implants. The fixed implant-supported denture is closer to the feel of real teeth (you’ll brush and floss normally), but it’s usually more costly than the removable implant-supported denture.
While more expensive than traditional ones, implant-supported dentures still cost less than other restorations like individual implant tooth replacements. They may also help deter bone loss, which may lead to a longer lasting fit with the dentures. Visit your dentist for an evaluation of your dental condition to see if you’re a good candidate for this advanced form of dental restoration.

The long-running hit show Dancing with the Stars has had its share of memorable moments, including a wedding proposal, a wardrobe malfunction, and lots of sharp dance moves. But just recently, one DWTS contestant had the bad luck of taking an elbow to the mouth on two separate occasions—one of which resulted in some serious dental damage.
Nationally syndicated radio personality Bobby Bones received the accidental blows while practicing with his partner, professional dancer Sharna Burgess. “I got hit really hard,” he said. “There was blood and a tooth. [My partner] was doing what she was supposed to do, and my face was not doing what it was supposed to do.”
Accidents like this can happen at any time—especially when people take part in activities where there’s a risk of dental trauma. Fortunately, dentists have many ways to treat oral injuries and restore damaged teeth. How do we do it?
It all depends on how much of the tooth is missing, whether the damage extends to the soft tissue in the tooth’s pulp, and whether the tooth’s roots are intact. If the roots are broken or seriously damaged, the tooth may need to be extracted (removed). It can then generally be replaced with a dental bridge or a state-of-the-art dental implant.
If the roots are healthy but the pulp is exposed, the tooth may become infected—a painful and potentially serious condition. A root canal is needed. In this procedure, the infected pulp tissue is removed and the “canals” (hollow spaces deep inside the tooth) are disinfected and sealed up. The tooth is then restored: A crown (cap) is generally used to replace the visible part above the gum line. A timely root canal procedure can often save a tooth that would otherwise be lost.
For moderate cracks and chips, dental veneers may be an option. Veneers are wafer-thin shells made of translucent material that go over the front surfaces of teeth. Custom-made from a model of your smile, veneers are securely cemented on to give you a restoration that looks natural and lasts for a long time.
It’s often possible to fix minor chips with dental bonding—and this type of restoration can frequently be done in just one office visit. In this procedure, layers of tooth-colored resin are applied to fill in the parts of the tooth that are missing, and then hardened by a special light. While it may not be as long-lasting as some other restoration methods, bonding is a relatively simple and inexpensive technique that can produce good results.

It’s estimated that between 10 and 40 million adults in the U.S. suffer from chronic jaw pain and disability. Healthcare providers refer to it as temporomandibular joint disorder (TMJD), a group of conditions characterized by pain and limited function with the jaw joints, as well as related muscles and tissues.
People with TMJD often experience popping, clicking or grating sounds when they move their lower jaw. The more serious symptoms, however, are severe pain and limited movement of the jaw. The causes of TMJD haven’t been fully substantiated, but it’s believed to be influenced by a person’s genetic background, their gender (most patients are women of childbearing age), their environment and behavioral habits. This uncertainty about the underlying causes has made it difficult to improve treatment strategies for the disorder.
One promising area of research, though, is suspected connections between TMJD and other health problems. In one survey of over 1,500 TMJD patients, nearly two-thirds indicated they had three or more other chronic conditions. Among the most frequently named were fibromyalgia, chronic fatigue syndrome, rheumatoid arthritis, and sleep disturbances.
We’re not quite sure how or why TMJD might be linked to these other conditions, but further study is underway. Researchers hope any knowledge uncovered could lead to advances in our ability to diagnose, treat and prevent TMJD.
Until then, the more traditional treatment approach remains the best course of action: medication to relax muscles and relieve pain; thermal therapies using hot and cold compresses during flare-ups; and physical therapy. Switching to softer foods temporarily may also give jaw muscles a rest from over-activity. Although jaw surgery is an option, we should consider it a last resort after other therapies have proven altogether ineffective in relieving pain and restoring function.
If you suspect you have TMJD, please visit a medical doctor first. Other conditions could mimic the symptoms of the disorder and would need to be ruled out first. If the diagnosis is TMJD, you’re not alone. You can receive information, support and updates on the latest research by visiting the TMJ Association at www.tmj.org.
