ReplacingaMissingToothisntJustAboutImprovingYourSmile

Seven out of ten Americans are missing at least one tooth due to decay, periodontal (gum) disease or injury. Unfortunately, the consequences go far beyond a missing tooth — the loss of even one could set in motion a cascade of problems.

Perhaps the most damaging of these problems is bone loss. Like other living tissue, bone has a life cycle — older cells dissolve (resorb) into the body and are replaced by fresher cells. This growth cycle in the jawbone receives stimulation from forces generated by teeth when we chew or bite. If a tooth is no longer present to provide this stimulation, the affected bone cells won’t regenerate at a healthy rate. Over time this causes the volume of bone to diminish, as much as 25% the first year after tooth loss.

The void left by a missing tooth can also adversely affect remaining teeth. Teeth are held in place by a tough but elastic tissue known as the periodontal ligament that lies between the tooth and the bone. The ligament enables teeth to move gradually in response to mouth changes so that the teeth remain tightly aligned with each other. When there’s a gap from a missing tooth, this tendency will cause the teeth on either side to move (or “drift”) toward the open space. Although a natural phenomena, it can result in a malocclusion (poor bite).

That’s why it’s important to replace a missing tooth with a life-like replica — not just for appearance’s sake, but also to improve function and prevent the rise of these other problems. While many options exist (from removable dentures to fixed bridges) the choice most preferred by dentists and patients is the dental implant.

An implant replaces the tooth root as well as the crown, because it’s imbedded securely into the jawbone. Because of a natural affinity with titanium, the principal metal used in implants, bone cells will grow to its surface. Not only will this anchor the implant more securely, it will slow or even stop bone loss.

If you have a missing tooth, you should visit us as soon as possible to consider your options for a replacement. A new tooth will help stop even greater problems from occurring.

ConsiderBoneHealthWhenDecidingBetweenImplantsandDentures

Losing permanent teeth is never good — unlike primary teeth, no natural replacements wait in the wings. But the good news is you have a number of options for replacing them with life-like prosthetic (false) teeth.

Today's premier choice is dental implants, preferred by dentists and patients alike for their durability and life-likeness. But because of their cost when replacing multiple teeth, many people opt for traditional dentures. And now dentures are easier to wear and maintain thanks to new, advanced materials and designs.

Still, there's one major area where implants have the definite edge over dentures — long-term bone health. Older bone cells die and dissolve (resorb), replaced then by newly formed cells. Teeth help perpetuate this cycle through the forces generated when we chew that travel through the roots to stimulate the formation of new bone.

But because this stimulation through a tooth ends when it's lost, new bone beneath the empty socket may not keep up with the resorption rate of older bone. As a result, you could lose as much as a quarter of normal bone width in just the first year after losing a tooth.

This bone loss will continue to accumulate even if you wear dentures, which can't replicate the bone growth stimulation of natural teeth. What's more, the constant pressure on the bony ridge of the gums can accelerate bone loss. Eventually, the firm, comfortable fit you first had with your dentures will become looser and less comfortable with the shrinking bone volume.

Implants, on the other hand, can stop bone loss and may even reverse it. This is because the titanium metal of an implant has a special affinity with bone cells that readily grow and adhere to it. This creates the anchorage responsible for the implant's durability, but it's also healthy for the bone.

Of course, this doesn't have to be a binary choice between the two restorations thanks to a new hybrid advancement that combines implants with dentures. We can install as few as two implants to support a removable denture. You'll enjoy greater stability, fit and durability with your dentures, while also improving bone health through the implants.

So before you decide on a dental restoration, be sure to discuss with us your implant options. Your oral health and appearance could benefit immensely.

3CuttingEdgeWaysYouCouldBenefitfromDentalImplants

Since their introduction over thirty years ago, dental implants have become the most popular choice for dental restoration. Their large variety of shapes and sizes — a far cry from the limited choices of the 1980s — has only served to increase their popularity.

In recent years there's also been an expansion in their applicability. Most people recognize them as replacements for individual teeth — but they can do much more. They're now playing a pivotal role in other dental restorations or situations.

Here are 3 of those “cutting edge” ways implants could change your dental health and smile for the better.

Fixed bridgework. In a traditional bridge, prosthetic (false) teeth use the natural teeth on either side of the empty space for support. In this updated version, implants become the support base for the bridge. For example, a bridge as small as three crowns can be supported by two implants attached to the outside crowns of the bridge. Four to eight implants can support a bridge as large as an entire arch of teeth.

Over-dentures. In cases of significant bone loss, a full or partial denture may be a better option than a fixed bridge. Traditional dentures, though, can contribute to even more bone loss, which can cause the dentures to eventually lose their fit. Implants not only can help stop further bone loss but can also stimulate increased bone density. Two or more standard or mini-sized-sized implants can support a full or partial denture.

Orthodontics anchorage. People with missing teeth aren't the only ones who can benefit from implants. While most bite repairs only require the back teeth to provide anchorage for braces, certain complex bites may need a different point of anchorage. Orthodontists can create a more feasible anchorage point with an implant or a temporary anchorage device (TAD) imbedded in the jaw. This can help isolate teeth that need to be moved from those on the arch that don't.

AntibioticsCouldHelpEnsureyourImplantSurgeryisSuccessful

If you're considering dental implants to replace one or more missing teeth, you'll need to undergo a minor to moderate surgical procedure (depending on the number of implants) to install them. Depending on your current health status and medical history, you may need antibiotics before or after the procedure to help ensure a successful outcome.

Although implants have a high success rate (over 95%), they can still fail — and bacterial infection is a major culprit. Installing implants requires surgically accessing the bone through the gum tissues; you may also need other invasive procedures like tooth extraction or bone or gum tissue grafting. These disruptions to the soft tissues can introduce bacteria into the bloodstream.

In certain individuals, this can increase infection risk not only around the implant but also in other parts of the body. You may be at higher risk, for example, if you have serious health problems like cardiovascular disease or diabetes, a weakened immune system, you use tobacco or you're over or under normal weight. The American Dental and American Heart Associations both recommend antibiotics before dental implant surgery as a preventive measure against infection if you have a prosthetic heart valve, a history of infective endocarditis, a heart transplant or some congenital heart conditions.

For other patients with low to moderate risk for infection, there's vigorous debate on administering antibiotics before implant surgery. There are some side effects to antibiotic use, ranging from diarrhea to allergic reactions, and an increased concern in general to the developing resistance of many infectious agents due to the prevalent use of antibiotics. Many dentists and physicians are becoming more discriminate in the patients for which they prescribe antibiotics before surgical procedures.

It really comes down, then, to your particular case: not only the specific procedures you need but also your general health. After weighing these factors against the possible benefits for protecting your health and improving your odds of a successful outcome, we'll recommend whether antibiotic treatment for implants is right for you.

JohnnysTeethArentRottenAnyMore

Everyone has to face the music at some time — even John Lydon, former lead singer of The Sex Pistols, arguably England’s best known punk rock band. The 59-year old musician was once better known by his stage name, Johnny Rotten — a brash reference to the visibly degraded state of his teeth. But in the decades since his band broke up, Lydon’s lifelong deficiency in dental hygiene had begun to cause him serious problems.

In recent years, Lydon has had several dental surgeries — including one to resolve two serious abscesses in his mouth, which left him with stitches in his gums and a temporary speech impediment. Photos show that he also had missing teeth, which, sources say, he opted to replace with dental implants.

For Lydon (and many others in the same situation) that’s likely to be an excellent choice. Dental implants are the gold standard for tooth replacement today, for some very good reasons. The most natural-looking of all tooth replacements, implants also have a higher success rate than any other method: over 95 percent. They can be used to replace one tooth, several teeth, or an entire arch (top or bottom row) of teeth. And with only routine care, they can last for the rest of your life.

Like natural teeth, dental implants get support from the bone in your jaw. The implant itself — a screw-like titanium post — is inserted into the jaw in a minor surgical operation. The lifelike, visible part of the tooth — the crown — is attached to the implant by a sturdy connector called an abutment. In time, the titanium metal of the implant actually becomes fused with the living bone tissue. This not only provides a solid anchorage for the prosthetic, but it also prevents bone loss at the site of the missing tooth — which is something neither bridgework nor dentures can do.

It’s true that implants may have a higher initial cost than other tooth replacement methods; in the long run, however, they may prove more economical. Over time, the cost of repeated dental treatments and periodic replacement of shorter-lived tooth restorations (not to mention lost time and discomfort) can easily exceed the expense of implants.

That’s a lesson John Lydon has learned. “A lot of ill health came from neglecting my teeth,” he told a newspaper reporter. “I felt sick all the time, and I decided to do something about it… I’ve had all kinds of abscesses, jaw surgery. It costs money and is very painful. So Johnny says: ‘Get your brush!’”

We couldn’t agree more. But if brushing isn’t enough, it may be time to consider dental implants.
