Losing teeth will certainly disrupt your otherwise beautiful smile. It could also potentially affect your food choices and whether or not you receive proper nutrition.
But something else just as consequential could be happening beneath the surface of your gums—you could be losing bone. Significant bone loss in the jaw could adversely affect remaining teeth and facial structure, as well as limit your future restoration choices.
To understand why this occurs we must first consider what bone is: living, cellular tissue. Like the body's other cells, bone has a life cycle: cells form, live and eventually dissolve (or resorb), and are then replaced by new cells. Stimulation from forces generated during chewing traveling up through the tooth roots to the jawbone keep this cycle going at a healthy pace.
But when a tooth is missing, so is this stimulation. This could slow the replacement rate and cause bone volume to gradually decrease. The jawbone width could decrease by as much as 25% the first year alone and several millimeters in height after just a few years.
Although dentures (a popular and affordable choice) can restore lost function and appearance, they can't duplicate this needed stimulation. They even accelerate bone loss by irritating and creating compressive forces on the bony ridges and the gums they rest upon.
One restoration, however, can actually help stop bone loss and may even reverse it: dental implants. This happens because an implant's metal titanium post imbedded in the jawbone attracts bone cells to grow and adhere to its surface. This could actually increase bone density at the site.
To gain this advantage, it's best to obtain implants as soon as possible after tooth loss. If you allow bone loss to occur by waiting too long, there may not be enough to properly support an implant. Even then it might be possible to build up the diminished bone through grafting. But if that's not possible, we'll have to consider a different restoration.
To determine the condition of your bone after losing teeth, visit us for a complete examination. Afterward, we'll be able to discuss with you the best way to address both your overall dental health and your smile.

Periodontal disease may start in the gums’ superficial layers, but it’s not likely to stay there. As the disease moves deeper it can wreak havoc on tooth roots and bone as well as gum tissue attachments. Teeth with multiple roots are in particular peril because of the “forks” called furcations that form where the roots separate from each other. Infected furcations can be very difficult to treat.
We primarily treat gum disease by removing its main source, a thin film of bacteria and food particles called dental plaque that builds up on teeth. To remove it we most often use special hand tools or ultrasonic equipment to vibrate it loose. As the plaque and tartar diminish, the infection begins to wane.
But we can’t be completely successful in stopping the disease if any lingering plaque deposits remain. This especially includes furcations where the infection can cause significant damage to the roots. Although cleaning furcations of plaque can be difficult, it’s not impossible with the aforementioned tools and antimicrobial substances to disinfect the area.
The real problem, though, is access—effectively getting to the furcations to treat them. We may need to perform a surgical procedure called flap surgery where we create a hinged flap in the gum tissue to move it aside and access the root area beneath. Afterward we replace the flap and suture the tissue back in place.
In some cases, the infection may have already caused significant damage to the tissue and underlying bone. We may therefore need to graft gum or bone tissues to these damaged areas to stimulate re-growth. We may also need to surgically reshape the gum attachments around a tooth to make it easier in the future to access and clean the area.
These additional treatments around furcations can be very involved and labor-intensive. That’s why the best outcomes occur if we’re able to start treatment in the early stages of an infection. So, if you notice red, swollen or bleeding gums contact your dentist as soon as possible. Treating gum disease as early as possible will help ensure your tooth roots won’t suffer extensive damage.

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.
