BoneLosstheHiddenConsequenceofYourMissingTeeth

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.

TeenswithMissingTeethmayneedaTemporaryFixUntilTheyreOlder

Dental implants are widely considered by both dentists and patients as the premier choice for replacing missing teeth. Unfortunately, implants aren’t the appropriate choice for teenagers with missing teeth.

That’s because their jaws won’t fully finish most of their growth and development until early adulthood. An implant placed too early could become misaligned as the jaw matures. The best approach for a teenager is a temporary restoration until they’re old enough for an implant.

There are a couple of good options. One is a removable partial denture (RPD), prosthetic (false) teeth set in an acrylic base that mimics gum tissue at the locations of the missing teeth. RPDs, which stay in place by way of metal clips that fit over other teeth, are easy to wear and maintain.

On the downside, an RPD can break if you bite into something too hard. They can lose their fit and may need to be replaced with a new one. And, some teens aren’t quite keen on wearing a “denture.”

Another option is a bonded or Maryland bridge, a kind of fixed bridge. We bond dental material to the back of a prosthetic tooth with portions of the material extending out from either side of it.  We then bond these extending tabs to the back of the teeth on either side of the prosthetic tooth to hold it in place. Unlike traditional bridges, we can eventually remove it without any permanent alterations to the teeth it’s attached to.

Before we undertake a bonded bridge, though, we must make sure the gums and bone of the surrounding teeth are free from periodontal (gum) disease and are healthy and strong enough to support the bridge. We also need to be sure the patient doesn’t have a deep bite or a teeth grinding habit, which could cause the teeth to make contact with the tabs and break them.

The patient also needs the maturity to responsibly perform diligent oral hygiene: this type of bridge has a tendency to build up disease-causing plaque, so brushing twice and flossing once every day is critical. Not doing so increases the risk of tooth decay or periodontal (gum) disease, which could complicate a future implant.

We can discuss these options after a thorough dental examination of your teenager. Either way, we’ll be able to restore your teen’s smile until we can undertake a more permanent restoration.

ComplicationsfromMissingTeethCouldLimitYourReplacementOptions

There are plenty of options today for replacing missing teeth, including dental implants. But if the teeth have been missing for some time, complications can arise that limit your restorative options.

The most consequential possibility is bone loss. Bone has a life cycle: old cells dissolve (resorb), and are then replaced by new cells, stimulated to grow by the forces applied to the teeth during chewing. But the bone won't receive this stimulation if a tooth is missing — so growth slows down, which causes the bone volume to diminish with time.

Another complication can occur involving other teeth around the open space. These teeth will naturally move or “drift” out of their normal position into the missing tooth space. As a result we may not have enough room to place a prosthetic (false) tooth.

If either or both of these complications occur, we'll need to address them before attempting a restoration. Bone loss itself could eliminate dental implants as an option because they require a certain amount of supporting bone for correct placement. Bone loss could also make correcting misaligned teeth difficult if not impossible.

It might be possible, though, to regenerate lost bone with a bone graft. The graft is placed, sometimes along with growth stimulating substances, within the diminished bone area. It then serves as a scaffold upon which new bone can form.

If the bone becomes healthy again, we can then attempt to move any drifted teeth back to where they belong. Besides braces, there's another treatment option especially popular with adults: clear aligners. These are a series of removable, clear plastic trays that, like braces, exert gradual pressure on the teeth to move them. Patients wear each individual tray for about two weeks, and then switch to the next tray in the series to continue the process.

Unlike their traditional counterparts, clear aligners can be removed for cleaning or for special occasions. More importantly, they're much less noticeable than traditional braces.

Once any problems with bone health or bite have been addressed and corrected, you'll have a fuller range of options for replacing your missing teeth. With a little extra time and effort, you'll soon be able to regain a smile you'll be proud to display.

ThoughnotAlwaysSeenitsStillImportanttoReplaceaMissingBackTooth

Your front teeth are the stars of your smile — so it makes perfect sense to replace them if they’re missing. But is it really necessary to replace a largely unseen back tooth with an implant or bridgework?

The answer is an unequivocal yes. Your individual teeth are an interactive part of a dynamic mechanism that enables you to eat, speak and smile. They’re highly adaptable and can move incrementally to accommodate mouth changes — especially when one of them is lost.

Back teeth not only help us chew food efficiently, they also ease some of the pressure from front teeth as we chew. Our efficiency while chewing suffers when they’re missing; other teeth will wear faster and tend to move out of position, “drifting” into the space left by the missing tooth. And without their stimulation during chewing, new bone may grow at a slower rate to replace older bone, reducing bone volume over time.

So, whether visible or not, replacing a back tooth is the best course to take to prevent these adverse consequences. Your two best options are fixed bridgework or dental implants, each with their own advantages and disadvantages.

Bridgework has been the traditional method for replacing one or a few missing teeth: they’re long-lasting if cared for properly, have a life-like appearance that blends well with other teeth and are a good option when implants aren’t. But they require extensive altering of the anchor teeth (those used on either side of the bridge to secure it) and they’re highly prone for trapping food between them and the gums, increasing the risk of disease.

Dental implants are easily maintained and their installation doesn’t affect adjacent teeth as with a bridge. They’re also durable with a 95% success rate after ten years. On the other hand, the installation process can take several months and visits, and they require a certain amount of bone mass for proper placement and so aren’t ideal for certain patients.

Regardless of its location, if you have a missing tooth or one that may need to be removed, you should visit us for a complete examination. From there we can tell you how your mouth has been impacted by the missing tooth and which replacement option is best for you.
