Dental implant technology has advanced at such an astounding rate in recent years that you can now walk into a dentist's office with a problem tooth and out the same day with a new one. Unfortunately, not all dental situations allow for this possibility.
For example, you might be considering an implant many years after losing a tooth. But there's a potential problem: there might not be enough supporting bone. While an implant might still be possible, inadequate bone complicates the matter.
Because implants are essentially tooth root replacements, they require a certain amount of bone for stability and the best attractive outcome. As a general rule, implants need to be surrounded by at least 1.5-2.0 millimeters of healthy bone to support an implant. But you might not have enough if your tooth has been missing for awhile, regardless if you have or haven't worn dentures or other restorations.
That's because bone has a life cycle in which older cells die and newer ones form to take their place. As we chew or bite, the force generated travels up through the teeth to the bone to stimulate this new growth. Without a tooth the bone doesn't receive this stimulus, which can slow the growth rate. Over time the affected bone can lose its volume and density.
If we find you've experienced loss to the point your bone won't support an implant, that doesn't automatically mean this popular restoration is out of the picture. But it will require us first performing a procedure known as augmentation or bone grafting to help rejuvenate some of the lost bone.
With grafting, we place processed bone grafting material in the jaw through a minor surgical procedure to form a scaffold for new bone to grow upon. After several months this can result in several millimeters of new growth maintaining the width of the underlying bone, which in turn may be able to support an implant.
Bone grafting is quite common, often performed at the same time as tooth extraction if there's going to be a time lag before installing an implant. Even if performed later, though, it can successfully rejuvenate lost bone and make it possible for you to take advantage of durable, life-like implants.

What's an actor's most important feature? According to Vivica A. Fox, whose most recent big-screen role was in Independence Day: Resurgence, it's what you see right up front.
"On screen, your smile and your eyes are the most inviting things that bring the audience in" she said. "Especially if you play the hot chick."
But like lots of people, Vivica reached a point where she felt her smile needed a little help in order to look its best. That's when she turned to a popular cosmetic dental treatment.
"I got veneers years ago," Ms. Fox told Dear Doctor magazine in a recent interview, "just because I had some gapping that probably only I noticed."
What exactly are dental veneers? Essentially, they are thin shells of lustrous porcelain that are permanently attached to the front surfaces of the teeth. Tough, lifelike and stain-resistant, they can cover up a number of defects in your smile — including stains, chips, cracks, and even minor spacing irregularities like the ones Vivica had.
Veneers have become the treatment of choice for Hollywood celebs — and lots of regular folks too — for many reasons. Unlike some treatments that can take many months, it takes just a few appointments to have veneers placed on your teeth. Because they are custom made just for you, they allow you to decide how bright you want your smile to be: anywhere from a natural pearly hue to a brilliant "Hollywood white." Best of all, they are easy to maintain, and can last for many years with only routine care.
To place traditional veneers, it's necessary to prepare the tooth by removing a small amount (a millimeter or two) of its enamel surface. This keeps it from feeling too big — but it also means the treatment can't be reversed, so once you get veneers, you'll always have them. In certain situations, "no-prep" or minimal-prep veneers, which require little or no removal of tooth enamel, may be an option for some people.
Veneers aren't the only way to create a better smile: Teeth whitening, crowns or orthodontic work may also be an alternative. But for many, veneers are the preferred option. What does Vivica think of hers?
"I love my veneers!" she declared, noting that they have held up well for over a decade.
Implants are highly regarded by both dentists and patients for their versatility and durability. But it’s their life-like appearance that “seals the deal” as the restoration of choice — not only mimicking an individual tooth, but emerging from the gum line and blending indistinguishably with other teeth in color and symmetry.
To achieve this result, we must consider a few factors beforehand, particularly the amount of bone available at the intended implant site. An implant requires a certain amount of bone to properly position it for the most natural crown appearance. The bone present around adjacent teeth can also affect your appearance: in the absence of adequate bone the papillae, triangular shaped gum tissue between teeth, may not regenerate properly between the implant and the natural teeth. This can leave a noticeable void, what dentists call “black hole disease.”
Bone loss is a significant problem particularly after tooth loss. It’s quite possible for you to lose a quarter of the bone’s width in the first year after tooth loss. To avoid this, we often use bone grafting techniques immediately after extraction to lessen bone loss; if it’s already occurred we may be able to use similar reconstructive techniques to rebuild and encourage renewed bone growth. In the end, though, if there remains a significant level of bone loss it may be necessary to consider another option for tooth replacement other than implants.
The thickness of your gum tissue, a genetic trait, can also have an impact on the implant’s ultimate appearance. Thicker gum tissues are generally more resilient and easier to work with surgically. Thinner gum tissues are more susceptible to recession and tend to be more translucent, which could cause the underlying metal implant to be visible. Thus, working with thinner gum tissues requires a more delicate approach when trying to achieve a visually appealing result.
All these factors must be balanced, from implantation to final crown placement. But with careful planning and attention to detail throughout the process, many of these issues can be overcome to produce a satisfying result — a new and appealing 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.

Tooth decay is a highly destructive dental disease, responsible along with periodontal (gum) disease for most adult tooth loss. And we become even more susceptible to it as we get older.
One form of decay that’s especially prominent among senior adults is a root cavity. Similar to a cavity in the crown (visible tooth), this form instead occurs at or below the gum line in the roots. They happen mainly because the roots have become exposed due to gum recession, a common consequence of periodontal (gum) disease and/or brushing too hard.
Exposed roots are extremely vulnerable to disease because they don’t have the benefit of protective enamel like the tooth crown, covered instead with a thin and less protective mineral-like material called cementum. Normally, that’s not a problem because the gums that would normally cover them offer the bulk of the protection. But with the gums receded, the roots must depend on the less-effective cementum for protection against disease.
Although we treat root cavities in a similar way to those in the crown by removing decayed structure and then filling them, there’s often an added difficulty in accessing them below the gum line. Because of its location we may need to surgically enter through the gums to reach the cavity. This can increase the effort and expense to treat them.
It’s best then to prevent them if at all possible. This means practicing daily brushing and flossing to remove bacterial plaque, the thin, built-up biofilm on teeth most responsible for both tooth decay and gum disease. You should also visit your dentist at least twice a year for professional cleanings and advanced prevention methods like topical fluoride to strengthen any at-risk teeth.
You should also seek immediate treatment at the first sign of gum disease to help prevent gum recession. Even if it has occurred, treating the overall disease could help renew gum attachment. We may also need to support tissue regeneration with grafting surgery.
Root cavities are a serious matter that could lead to tooth loss. But by practicing prevention and getting prompt treatment for any dental disease, you can stop them from destroying your smile.
