There’s more to teeth than meets the eye. Hidden beneath the visible crown are the tooth’s roots set within the jawbone, secured and protected by the gums from bacteria and infection. But if the gums shrink back (recede), the roots become exposed and susceptible to disease, especially at the points where multiple roots branch from each other, areas called furcations.
It all begins with periodontal (gum) disease caused by built-up bacterial plaque from insufficient brushing and flossing. The infection triggers inflammation that over time weakens gum tissues. They begin to detach from the teeth, which can eventually lead to gum recession and root exposure.
This also causes bone loss, especially at the furcations. We can detect any loss (known as a furcation invasion) and how far along it may be with x-ray imaging or by manually probing with an instrument called a periodontal probe.
There are three general classes measuring furcation invasions. In the earliest, Class I, we can feel the invasion as a slight groove; in Class II, it increases to two or more millimeters across. In Class III the bone loss extends from one side of the root all the way to the other (a “through and through”).
At this stage a patient is in danger of losing the tooth, so we’ll have to act promptly. This means first removing accumulated dental plaque and calculus (tartar) to stop the infection and allow the gums to heal. With severe damage, we may need to assist healing with bone and gum tissue grafting, in which we place donor grafts to serve as scaffolding for the appropriate tissue to grow upon.
You can help prevent this situation by practicing effective daily hygiene and visiting your dentist for thorough cleanings at least twice a year (or more if recommended). And at the first signs of a gum infection—swollen, reddened or bleeding gums—make an appointment as soon as possible to have it checked. The sooner we can detect and treat gum disease, the less likely a furcation invasion or worse will be in your future.
Among dental restorations, implants are the closest prosthetic we have to real teeth. They not only replace the visible crown, but the titanium post imbedded in the jawbone adequately substitutes for the tooth root. Because of their unique design, implants are not only life-like, they’re highly durable and could potentially last for decades.
But while their success rate is remarkably high (more than 95% exceed the ten-year mark), they can fail. Ironically, one possible cause for implant failure is periodontal (gum) disease. Although an implant’s materials are themselves impervious to disease, the tissues and underlying bone that support the implant aren’t. If these natural tissues become infected, the secure hold the implant has can weaken and fail.
A gum infection usually begins with dental plaque, a thin biofilm of bacteria and food particles that builds up on tooth surfaces. Certain strains of bacteria within plaque can infect the gums. One particular form of the disease known as peri-implantitis starts as an initial infection and ensuing inflammation of gum tissues around an implant. The disease can quickly spread down to the bone and destroy the integration between the bone and the implant that helps keep the implant in place.
That’s why it’s important for you to keep the implant and the tissues around it clean of plaque, just as you would the rest of your natural teeth. This requires daily brushing and flossing around the implant and other teeth, and visiting your dentist regularly for more thorough dental cleanings.
You should also be alert to any signs of disease, especially around implants: gum redness, swelling, bleeding or pus formation. Because of the rapidity with which peri-implantitis can spread, you should see your dentist as soon as possible if you notice any of these signs.
Preventing gum disease, and treating it promptly if it occurs, is a key part of implant longevity. Preserving your overall dental health will help make sure your implant doesn’t become a loss statistic.
It's no exaggeration — dental implants have revolutionized teeth replacement. Life-like and durable, implants are the closest thing in design and function to a natural tooth.
In fact, there's only one thing better than a dental implant — a real tooth. For function and long-term oral health, you can't beat what nature provided you in the first place. So before you finally decide to remove and replace that problem tooth, consider these other options for saving it.
Root canal therapy. Tooth decay can do more than cause cavities — it can work its way into the pulp, the innermost layer of a tooth. If it isn't stopped here, it could continue on to the roots and put the tooth in real danger of loss. A root canal treatment removes the infection from the pulp and root canals and replaces the space with a filling. A life-like crown is then bonded or cemented to the tooth to protect it from further infection.
Aggressive treatment for periodontal (gum) disease. This other dental disease is just as damaging as tooth decay. Caused by bacterial plaque, the gums around a tooth become infected and inflamed. As it moves deeper into the tissues and inflammation progresses, it can affect supporting bone causing it to dissolve. To prevent this potential bone loss, it's important to seek out and remove hidden pockets of plaque. This may require surgery to access the roots for plaque and calculus (tartar) removal, but it's well worth it to preserve the tooth.
Bone grafting. As mentioned before, gum disease can ultimately lead to bone loss. But even when bone loss has occurred (a substantial threat to a tooth's survival) we may be able to reverse it with bone grafting techniques. During this procedure we insert grafting material at the loss site along with substances that stimulate growth. The graft serves as a scaffold for new bone cells to grow upon. Over time the bone volume increases and helps stabilize a weak tooth.
Of course, your best option is to avoid dental disease in the first place with daily brushing and flossing and regular dental visits for cleanings and checkups. That and treating dental disease in its earliest stages will help ensure you'll have the best teeth possible — your own.
