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.

Imagine not having your upper teeth for talking and eating, not to mention your appearance, and you’ll have some idea of what Beauty the bald eagle experienced after losing the top of her beak to a hunter’s bullet in northern Idaho. She couldn’t groom or feed herself and could barely drink water, relying instead on the conservation group that had taken her under their wing for assistance. But the magnificent raptor was eventually made whole and able once again to eat, drink and preen unaided. It took a visionary mechanical engineer and a very skillful dentist who designed and attached the first-of-its-kind bald eagle “dental” prosthetic — dubbed the “bionic beak.”
Prosthetic Teeth for Humans
Fortunately, the field of human prosthetic dentistry (or prosthodontics) is much more advanced than it is for our avian friends. We have several options for replacing missing teeth (as well as parts of missing teeth) that restore aesthetic appearance and functionality while potentially preventing other problems such as the drifting out of alignment or loss of remaining teeth.
Bridges. As the name suggests, these custom-made devices span the area that is missing a tooth/teeth. Fixed (not removable) bridges are made up of an artificial tooth/teeth fused between two crowns that fit over your existing teeth or dental implants (see below) on either side of the gap. There are removable bridges, but they are considered temporary fixes.
Dentures. These are custom-made removable replacements for missing teeth. Partial dentures offer a removable alternative to fixed bridges and are used when some teeth are missing in an upper or lower arch (jaw). Full dentures are used when all teeth are missing in an arch. Replacement teeth are embedded in an acrylic base that fits over your gums and mimics their color.
Dental Implants. These are the closest thing to having your own tooth/teeth back. An implant is a small titanium post that is placed in the jawbone beneath the gum to serve the same purpose as a tooth root. Once the bone joins to the implant (a process called osseo-integration), a lifelike crown is attached to it.
We would be glad to discuss which option would be right for you.

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.

For most people, replacing missing front teeth takes a higher priority over missing back teeth. The reason is obvious: others can see those missing in front, but not necessarily those in the back.
From a functional view, however, you should still consider replacing missing back teeth. Not only will it improve your chewing ability, it may also prevent a chain reaction of negative effects to your remaining teeth.
Teeth are held in place in the jawbone by a membrane called the periodontal ligament. The ligament is a living tissue that allows teeth to move to keep contact with adjacent and opposing teeth as natural wear occurs. When a space is created by a missing tooth, this natural movement accelerates and the teeth may shift beyond normal ranges.
As a result you can encounter excessive mobility of teeth from bite irregularities, uneven tooth wear, bone loss, potential painful problems with the temporo-mandibular joints (connecting the lower jaw to the skull), and a loss in facial height.
There are three basic options for this kind of tooth replacement. The best option is dental implants: these free-standing replacements don't normally affect surrounding teeth, they're easier to clean, and they help support the bite. On the downside, there must be enough remaining bone to support the implant.
The next best option is a fixed bridge. This option only works, however, if there are teeth on either side of the missing tooth space capable of supporting the bridge, and they must be reduced in size by removing the enamel with the dental drill. They also have a tendency to retain plaque, the main cause of gum disease.
That leaves the last, and least favorable, option, a removable partial denture. They may also trap food and be difficult to wear. They can move in the mouth, stressing — and possibly loosening — the remaining teeth that hold them in place. With all its drawbacks, though, if a partial denture is the only solution to missing back teeth, it's a better alternative than doing nothing and risking long-term problems.
