Losing teeth can make it more difficult to eat, not to mention the effect it can have on your smile. But that could be just the beginning of your problems. Missing teeth can contribute to extensive bone loss within your jaws and face. Here's why.
Bone is like any other living tissue—cells develop, function and eventually die, and new cells take their place. Forces generated during chewing stimulate this new growth, helping the jawbone maintain its normal volume and density.
But you lose this stimulus when you lose teeth. This can cause a slowdown in bone cell regrowth that can eventually diminish bone volume. And it can happen relatively quickly: you could lose a quarter or more of jawbone width around a missing tooth within a year.
As this loss continues, especially in cases of multiple missing teeth, the bone can eventually erode to its base level. This loss of dental function can make chewing more difficult, place more pressure on the remaining teeth and adversely affect facial appearance. It could also prevent an implant restoration to replace missing teeth.
Dentures and other forms of dental restoration can replace missing teeth, but not the chewing stimulus. Dentures in particular will accelerate bone loss, because they can irritate the bony gum ridges they rest upon.
Dental implants, on the other hand, can slow or even stop bone loss. Implants consist of a metal post, typically made of titanium, imbedded into the jawbone at the site of the missing tooth with a life-like crown attached. Titanium also has a strong affinity with bone so that bone cells naturally grow and adhere to the implant's surface. This can produce enough growth to slow, stop or even reverse bone loss.
This effect may also work when implants are combined with other restorations, including dentures. These enhanced dentures no longer rest on the gums, but connect to implants. This adds support and takes the pressure off of the bony ridge, as well as contributes to better bone health.
If you've lost a tooth, it's important to either replace it promptly or have a bone graft installed to help forestall any bone loss in the interim. And when it's time to replace those missing teeth, dental implants could provide you not only a life-like solution, but a way to protect your bone health.

If you've decided on a dental implant to replace a missing tooth, you've made a great choice. Implants are a big favorite of both dentists and patients, not only for their life-likeness, but also their durability. Studies show that more than 95% of implants survive after ten years.
As you may know, single tooth implants are composed of two main parts: a metal post (usually titanium) imbedded in the jawbone; and a life-like crown affixed to the end of the post. But what you may not know is that there are two ways to attach the crown—either with screws or with dental cement.
Neither way is superior to the other—both have their own set of advantages and disadvantages. A cemented crown, for instance, usually looks more like a natural tooth than a screw-retained crown (more about that later) and dentists have more flexibility in making them look natural.
But cemented crowns require an additional piece of hardware called an abutment to better match it with the implant, something unnecessary with a screw-retained crown. Some people can also experience a reaction to the cement resulting in inflammation or even bone loss. And once installed, removing the crown later for repair or replacement is much more difficult than with a screw-retained crown.
Besides attaching directly to the implant, screw-retained crowns don't require cement and are more easily attached and removed. But the screw-hole can pose some aesthetic problems: Although it can be filled with a tooth-colored filling, the tooth's appearance isn't as ideal as a cemented crown.
So, which one is best for you? That will depend on the type and location of teeth being replaced, as well as your dentist's preferences. For instance, a more attractive cemented crown may be better for a visible front tooth, while a screw-retained crown might be a good choice for a back premolar or molar where appearance isn't as big a factor.
In the end, it's likely your dentist will discuss the pros and cons for each method as it pertains to your individual case. Whichever way your crown attaches, the end result will still be a life-like tooth that could last you for years to come.

When dental implants hit the scene in the 1980s, they revolutionized the field of dental restorations. But as groundbreaking as they were then, they're even more advanced now.
Some of the advancements have to do with improvements in implant design and manufacturing. Implant sizes and shapes were once quite limited, but today they come in a variety of forms to better match the types of teeth they replace.
But there has also been important progress in complementary technologies that help us realize better outcomes. Many of these other advances have had a positive impact on the planning and surgical stages of implant installation.
CT/CBCT scanning. For the best outcome, it's critical to install an implant at the most appropriate location on the jaw. This can be difficult to determine, however, because of the location of oral and facial structures like nerves or sinuses that might interfere with implant placement. But using a type of computer tomography (CT) scanning called cone beam CT, we can produce a 3-D computer graphic image that helps us navigate possible obstructions as we pinpoint the ideal location for an implant.
Digital smile displays. We're now able to produce digital models of the mouth, which can assist with more than implant placement—we can also use them to visualize what a new smile with implants will look like before we install them. This is especially helpful in situations where only a few teeth need to be replaced: We want to ensure that the new implant crowns blend seamlessly with the remaining teeth for the most natural appearance.
Custom-made surgical guides. We've been using surgical guides to mark the exact drilling locations during implant surgery for many years. But 3-D printing technology can now help us produce surgical guides that are even more useful and precise. Using a 3-D printer, we can produce oral devices based on the patient's individual dental dimensions captured through digital scanning. That produces a better fit for the guide on the teeth and more accurate implant placement.
Together, these and other technological advances are helping us achieve even more successful results. Not only can they help us produce implant outcomes that can last for years or even decades, but also the most beautiful smiles possible.

A fair number of people with total tooth loss have arrived at this point after a long history of dental issues. It's quite likely they've had a series of bridges or partial dentures over the years to accommodate lost teeth at various times before moving to full dentures.
For many, it often seems easier to extract any remaining teeth at some point and simply move on to a total restoration. It's often better for oral health, however, to preserve any remaining teeth for as long as possible and update restorations as needed. Dental implants could make this type of staged restoration strategy much easier to manage.
Implants are tiny metal posts surgically imbedded in a patient's jawbone. Over time, bone cells grow and adhere to the implant's titanium surface, creating a strong and durable hold. Its most familiar application is as a replacement for an individual tooth.
But because of their strength and durability, this advanced dental technology is also used to support other restorations like bridges and partial or full dentures by way of a few strategically placed implants. And it's in that role that they can be useful in planning and implementing future restoration upgrades when needed.
Under this strategy, we add implants to supplement pre-existing implants from earlier restorations to support the updated dental work. For example, we might have previously placed an implant supporting a single tooth or a small bridge. When the need later arises for a partial denture, we can add additional implants to be used with the earlier one to support the new denture.
If the earlier implants have been well-placed, we need only to add enough implants necessary to support a full denture when the time comes. How many will depend on the particular type of denture: A removable lower denture may only require one additional implant with one already in place. A fixed upper or lower denture will require enough to bring the number to between four and eight.
Taking this long-term approach can be more cost-effective in the long-run. More importantly, it can make for a smoother path for the patient and help preserve remaining teeth for as long as possible.

If you’ve had the misfortune of losing all or most of your teeth (a condition called edentulism), you still have effective options for restoring lost form and function to your mouth. There is, of course, the traditional removable denture that’s been the mainstay for edentulism treatment for decades. If you haven’t experienced significant bone loss in the jaw, though, a fixed bridge supported by titanium implants could be a better choice.
But what if bone loss has ruled out an implant-supported fixed bridge? There’s still another option besides traditional dentures — a removable “overdenture” that fits “over” smaller diameter implants strategically placed in the jaw to support it.
A removable, implant-supported bridge offers a number of advantages for edentulism patients with significant bone loss.
Speech Enhancement. Any denture or bridge supported by implants will have a positive impact on speech ability, especially involving the upper jaw. But patients who’ve previously worn removable dentures may not see a dramatic difference but will still be able to benefit from the greater stability of the denture, particularly if the dentures were previously unstable.
Hygiene. A removable denture allows better access to implant sites for cleaning. Better hygiene reduces the risk of gum disease and further bone loss.
Long-Term Maintenance. Regardless of which type of implant supported restoration is used, it will eventually require some maintenance. A well-designed removable overdenture can make any future maintenance easier to perform.
Aesthetics. For personal satisfaction, this is often the ultimate test — how will I look? As a product of the evolving art of facial aesthetics, removable dentures supported by implants can replace lost tissues and restore balance to the face, and often produce a remarkable smile “makeover.”
To find out which restoration option is best for you, you should first undergo a thorough examination to determine the status of your facial and jaw structures, particularly the amount of bone mass still present. Ultimately, though, the decision should be the one that best fits your functional needs, while fulfilling your desires for your future smile.
