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.

While many people still consider dental implants the "new kids on the block" in dental restoration, they're now in their fourth decade of use. And since their inception implant technology has continued to improve and revolutionize how we replace missing teeth.
Implants are a different "species" compared to other restoration methods. To be precise, an implant is a tooth root replacement—usually a titanium metal post imbedded directly into the jaw bone. Titanium is not only a biocompatible metal, but bone cells naturally grow on its surface to create a strong and durable hold. It's this secure hold that's most responsible for implants' high long-term success rate.
But we should also credit some of this success to the steady stream of advances over the years in implant construction and supporting technologies. For one thing, we're now more accurate and precise with implant placement thanks to advances in computer tomography (CT) and cone beam CT (CBCT) scanning.
These digital processes merge a series of images taken by a special camera to form a three-dimensional model of the jaw. We can manipulate this model on a computer monitor to view it from different vantage points. It can help us locate and avoid anatomical structures like nerves and sinuses when determining where to place a future implant. CT and CBCT are especially useful when there's a concern about adequate available bone, a necessity for stable implants.
Technology has also improved how we create surgical guides, often used during implant surgery to obtain the most accurate results. Surgical guides are custom-made devices that fit over the teeth with the drilling locations for the implants marked on them. Recent advances in 3-D printing have made these guides even more accurate so that they fit more securely in the mouth. This greater stability increases their accuracy during the drilling sequence during surgery.
These and other advances are helping ensure every implant is a success story. The end result is both a functional restoration and a beautiful smile.

If you have a problem tooth we’ve recommended removing, those “Tooth in one day” ads—a tooth removed and an implant placed at the same time—might start to pique your interest. But there are a few factors we must consider first to determine if this procedure is right for you. Depending on your mouth’s health conditions, you may need to wait a little while between tooth extraction and implantation.
Here are 3 timing scenarios for receiving your implant after tooth removal, depending on your oral health.
Immediately. The “tooth in one day” scenario can be much to your liking, but it could also be tricky in achieving the best results. For one, the implant may fit too loosely—the bone around the socket might first need to heal and fill in or undergo grafting to stimulate regeneration. In other words, immediate implant placement usually requires enough supporting bone and an intact socket. Bone grafting around the implant is usually needed as well.
After gum healing. Sufficient gum coverage is also necessary for a successful outcome even if the bone appears adequate. To guard against gum shrinkage that could unattractively expose too much of the implant, we may need to delay implant placement for about 4 to 8 weeks to allow sufficient gum healing and sealing of the extraction wound. Allowing the gums to heal can help ensure there’s enough gum tissue to cover and protect the implant once it’s placed.
After bone healing. As we’ve implied, implants need an adequate amount of supporting bone for best results. When there isn’t enough, we might place a bone graft (often immediately after tooth extraction) that will serve as a scaffold for new bone to grow upon. Depending on the degree of bone loss, we may wait until some of the bone has regenerated (about 2 to 4 months) and then allow the natural process of bone cells growing and adhering to the implant (osseointegration) to complete the needed bone growth. If bone loss is extensive, we may need to wait until full healing in 4 to 6 months to encourage the most stable outcome.

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.

Dental implants are considered today’s premier method for restoring missing teeth. Obtaining an implant, though, is often a long process and the implants themselves must be surgically placed within the jaw bone. Nothing to worry about, though: implant surgery is a minor to moderate procedure akin to a surgical tooth extraction.
Still like any surgery, this procedure does involve cutting into the soft tissues of the gums and could allow oral bacteria to enter the bloodstream. While most bacteria in the mouth are harmless (and even beneficial) a few strains can cause disease. For some people, especially those with certain heart conditions or joint replacements, this could potentially cause serious issues in other parts of their body that might be highly susceptible to infection.
To guard against this, it’s been a long-standing practice in dentistry to prescribe antibiotics to certain high risk patients before a procedure. Although this departs from the normal use of antibiotics for already occurring infections, due to the circumstances this has been deemed an acceptable measure to prevent disease.
In the past, the categories of patients for which preventive antibiotics were appropriate had been more extensive. In recent years, though, both the American Dental Association and the American Heart Association have adjusted their recommendations. Today, your dental provider may recommend antibiotic pre-treatment if you have a prosthetic (artificial) heart valve, a history of infective endocarditis (inflammation of the inner linings of the heart), a heart transplant or certain congenital heart conditions.
While physicians may still recommend premedication with antibiotics for patients with joint replacements, it’s not as blanket a standard as it might once have been. It’s now only recommended for certain cases, such as patients who’ve received a prosthetic joint within the last two years.
There’s still an ongoing debate about the effectiveness of antibiotic pre-medication. However, there’s evidence medicating before procedures with antibiotics can be beneficial in avoiding infection. If you fall into one of the categories just mentioned or are concerned about infection, feel free to discuss with your dentist if using antibiotics before your implant surgery is wise move for you.
