Not long ago, the most affordable option for total tooth loss was a removable denture. Dentures, prosthetic (false) teeth set in gum-colored acrylic plastic bases, can effectively restore function and appearance. But the appliance continues to have one major drawback: it can accelerate bone loss in the jaw.
Like other living tissues, older bone cells die and become absorbed into the body (resorption). Normally they're replaced by newer cells. The forces generated when we chew our food travel through the teeth to stimulate this new growth. This stimulus ends when we lose our teeth, and so cell replacement can slow to an abnormal rate. Eventually, this causes bone loss.
Removable dentures can't provide this stimulation. In fact, the pressure generated as they compress the gums' bony ridges can even accelerate bone loss. That's why over time a denture's fit can become loose and uncomfortable — the bone has shrunk and no longer matches the contours of the dentures.
In recent years, though, a new development has been able to provide greater support to dentures while at the same time slowing or even stopping bone loss. We can now support dentures with dental implants.
Implants are best known as individual tooth replacements: a titanium metal post replaces the root, while a life-like porcelain crown attaches to the post to replace the visible tooth. In addition to providing a longer-lasting alternative to removable dentures, implants provide a very important health benefit: they improve bone density because they mimic the function of natural teeth. Bone cells are naturally attracted to the titanium; they adhere to the titanium post and are stimulated to grow through the action of chewing, increasing bone density and securing the implant's hold in the jaw.
Using the same technology we can support removable dentures, or even full fixed bridges. Rather than rest directly on the bony ridges, a denture can make a secure connection through a coupling system with just a few strategically placed implants. We can also permanently attach a full bridge by fastening it to a few implants with screws.
Not only do we eliminate the pressure from dentures compressing the gums and bone tissue, we can actually stimulate bone growth with the implants. Although more costly upfront than traditional dentures, unlike traditional dentures which must be replaced every five to seven years, long-lasting implants may be more cost-effective over the long-run.

Eating is one of the pleasures — and necessities — of life, but people who suffer from temporomandibular joint disorders (TMD) may find eating no pleasure at all — and they may not be eating the right nutritional balance of foods.
TMD is a collection of conditions that affect the jaw joints, connecting muscles and other related facial structures. If you've been diagnosed with TMD, you're probably not only acquainted with severe pain, but also difficulty opening your jaw as widely as normal. This can make it difficult to chew certain foods.
There are a number of effective treatments for TMD, including thermal therapy (hot or cold packs), joint exercise, medication or surgery (as a last resort). But these treatments often take time to make a noticeable difference. In the meantime, you may still need to change what and how you eat to ensure you're getting the nutrients your body needs.
The overall strategy should be to soften and reduce the chewing size of your food. With fruits and vegetables, you'll want to peel and discard any hard or chewy skins, and then chop the fruit flesh into smaller pieces. Steam or cook vegetables like greens, broccoli or cauliflower until they're soft and then chop them into smaller portions. You might also consider pureeing your fruit (and some vegetables) to make smoothies with ice, milk or yogurt, or vegetable-based soups.
Treat meat, poultry or seafood in much the same way, especially biting sizes. Besides cooking meats to tenderness, include moisteners like broths, gravies or brazing liquids to further make them easier to chew.
Dairy foods are an important source of nutrition: eat milk-based products like yogurt or cheese as much as you can handle. If you have problems with these or also nut butters, then consider meal replacement beverages like instant breakfast or whey protein beverages.
And don't forget whole grains. Although some can be hard to chew, you can prepare them in hot cereal form (like oatmeal) to tenderize them. You can also prepare thin bread toast and cut into smaller pieces.
Hopefully, your treatment will bring your TMD symptoms under manageable control. Until then (and after, if need be) adjust your diet to eat the foods that keep you healthy.
Dental implants are all the rage. And why not — not only are these tooth replacements life-like and highly functional, they have an amazing 95% ten-year success rate.
Some of that success is due to their unique design. Technically a root replacement, an implant's metal titanium post is surgically placed in the jawbone, where bone grows and adheres to it over time. This creates a strong connection that stands up well to the forces created by biting and chewing.
But there's more to their longevity than design. Success also depends on a careful, planned process that begins long before surgery.
It starts with a detailed oral examination to determine the best placement for the implant. Besides regular x-rays, we may also perform CT scans to create a three-dimensional view of your jaw. With this we can locate and avoid nerves, sinus cavities or other structures near the implant site.
The examination also helps us determine if you've experienced any bone loss, a normal occurrence after tooth loss. Implants require an adequate amount of bone to achieve the best position. A good position ensures future bone integration and the best appearance result.
The same attention to detail extends to the actual surgery to place the implant. We fashion the site to receive the implant by sequentially drilling larger tapered channels until we achieve the right size fit for the implant. During drilling we avoid overheating the bone, which could ultimately weaken and damage the implant's stability.
We'll also need to provide protection for the implant while it integrates with the bone. In most implantations, we do this by suturing the gum tissue over the implant. We take a different approach with a “Tooth in a Day” procedure where we attach a crown (the visible portion of the tooth) right after implant surgery. In this case we'll install a crown (which is actually temporary) that's a little shorter than the adjacent teeth. The natural teeth around it will absorb the forces produced while chewing and not the implant crown.
Focusing on these and other factors will greatly reduce the risk of implant failure. Paying careful attention to them helps ensure your new smile is a lasting one.

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.

Periodontal (gum) disease is a serious matter. Not only can it wreak havoc with your gums, it could also cause bone loss in the jaw that supports your teeth.
Gum disease is a bacterial infection that originates from a thin film of food particles on tooth surfaces called plaque. If you're not diligent about removing plaque through daily brushing and flossing, it can become a feeding ground for certain strains of bacteria that trigger gum infections. Left untreated, the disease can advance deeply into the teeth's supporting structures.
We're particularly concerned about furcations, the specific locations where multiple roots of a tooth fork or separate. When these locations become infected we call it a furcation involvement or invasion. The bone along the furcation will begin to deteriorate and dissolve, following a progression of stages (or classes) we can measure by probing the gum tissue or through x-ray evaluation:
- Class I: the furcation feels like a groove, but without any noticeable bone loss;
- Class II: a depression of about two or more millimeters develops indicating definite bone loss;
- Class III: Â bone loss now extends from one side of the root to the other, also known as “through and through.”
Treating furcation involvements can prove challenging because the infection is usually well below the gum line (sub-gingival). As with all gum disease treatment, our primary approach is to remove all plaque and calculus (hardened plaque deposits) where we find it, including around the roots. We typically use specially shaped instruments to clean the root surfaces. We can also employ an ultrasonic device that loosens plaque and calculus with high-frequency vibrations and flushed away with water.
Sometimes, we may need to surgically access involved furcations to clean them and stimulate bone growth with grafting. We can also use surgery to make the areas easier to clean — both for you and for us during your regular office cleanings — to prevent reoccurrences of infection.
Of course, preventing gum disease in the first place is your best defense against oral problems like furcation bone loss. Be sure you brush and floss every day, and visit us for thorough cleanings at least twice a year (unless we recommend more). This will help make sure not only your gums, but the bone that supports your teeth stays healthy.
