People have depended on dentures for generations—and they still do. That's because they work, both in restoring dental function and a smile marred by missing teeth.
But they have one major drawback related to bone health. That's because living bone has a life cycle: as older cells die, new ones form to take their place. The pressure generated when we chew stimulates this growth. But when this stimulus goes missing along with the teeth, the cell replacement rate slows and bone volume and density gradually diminishes.
Traditional dentures can't transmit this chewing pressure stimulus. And because they rest directly on the gum ridges, they can adversely affect the underlying bone and actually accelerate bone loss.
But implant technology potentially solves this bone loss problem with dentures by using implants rather than the gums to support them. It's a two-fold benefit: first, the implants relieve much of the irritation to the gums and bone caused by traditional dentures. Primarily, though, the implants themselves can slow or even stop continuing bone loss.
Most implants are made of titanium, not only because it's compatible with the body, but also because it has an affinity with bone. Over time bone cells grow on the titanium post imbedded in the jawbone. This process not only creates stability and durability, it can improve bone health.
In recent years dentists have incorporated implants with dentures to create two exciting treatment options. With one option, the dentist installs two or more implants in the jaw, to which a specially fitted removable denture can be attached. You would still have the ease of removing the denture for cleaning, while gaining greater stability and a reduced risk of bone loss.
The other option is a fixed denture (or bridge) attached permanently to implants. For this option, a patient's jawbone must be adequate and healthy enough to support at least four to six implants. A fixed denture is also often costlier and more complex than a removable denture, but it can feel more like real teeth. It also promotes better bone health too.
Although both options are more expensive than traditional dentures, they can pay dividends for long-term dental health. Implants could help you enjoy your new dentures and resulting smile for a long time to come.

Unlike other tooth replacement options, dental implants require a surgical procedure. But don't let your imagination run wild — the procedure is relatively minor and easy for most people to undergo.
Implants are unique among restorations because they replace a tooth's root. A metal titanium post, substituting for the root, must be surgically placed into the jawbone. While the procedure itself is simple and no more involved than a tooth extraction, it does require careful attention to detail before, during and afterward.
Our first step is to examine the target site with x-rays (often CT scanning) to pinpoint the best location for placement. This is critical because where we place the implant will have a huge bearing on how attractive and natural the implant finally appears. From this evaluation we frequently create a surgical guide.
Surgery begins with a local anesthesia to completely numb the site. You will feel no pain during the procedure and only minimal discomfort for a few days afterward. We then make small incisions in the gums to access the bone and create a small channel or hole.
Using the surgical guide, we then initiate a drilling sequence that gradually increases the size of the channel until it's the size and shape of the implant post. One thing we must do at this point is take our time: we use gentle pressure and water-cooling to avoid overheating and damaging the bone.
Once we're finished with drilling we remove the implant from its sterile packaging and imbed it directly into the prepared channel. It's then a matter of verifying the location with x-rays and then closing the gum tissue with self-absorbing sutures if necessary.
Most patients only need mild pain medication like aspirin or ibuprofen to manage discomfort afterwards. You won't even notice it in a week or less. After several weeks in which the bone grows and adheres to the implant (a process called osseointegration), you'll be ready for the final step, attaching the life-like porcelain crown to the implant.
Although the process can take several weeks to months, your discomfort should be minimal at any stage. In the end, your patience will be rewarded with a new, more attractive smile.

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.

It’s a common problem for denture wearers: after years of a comfortable fit, your dentures now seem to be uncomfortably loose. The reason, though, may have more to do with bone loss than the dentures.
Bone is a living tissue with a life cycle — it forms, it ages, and it eventually dies and dissolves (resorbs). It’s replaced with new bone and the cycle repeats. Additionally, the forces generated when we bite or chew are transmitted from the teeth to the jaw, which helps stimulate new bone growth. When the natural teeth are missing, however, the bone no longer receives this stimulus. Resorbed bone isn’t replaced at a healthy rate, which leads over time to bone loss.
Denture construction can also contribute to bone loss. The denture palate rests for support on the bony ridges that once held the teeth. Over time the compressive forces of the dentures apply damages and reduces the volume of gum tissue and eventually does the same to the bone. Combining all these factors, the reduced gum and bone volume will eventually alter the denture fit.
There are a few alternatives for correcting loose dentures. One is to reline them with new plastic, as either a temporary fix performed during an office visit or a more permanent relining that requires sending your dentures to a dental lab. Depending on the rate of bone loss, a patient could go through several denture relinings to accommodate ongoing changes in the jaw. At some point, though, it may be necessary to create a new set of dentures.
A third alternative that’s becoming increasingly useful is to incorporate dental implants into the denture design. Implants can of course be used to replace individual teeth, but a few strategically placed implants (usually of smaller dimension) can serve as a support platform for a removable denture. This relieves some of the compression force of a traditionally worn denture and can slow bone loss.

Dental implants are today’s closest restorative facsimile to natural teeth. And they’re versatile: not only can they replace single teeth but they can also support bridges or dentures.
But since one of their crucial components is made of metal, are you out of luck obtaining this state-of-the-art dental restoration if you have a metal allergy?
The answer is: probably not—it’s rare for implants to cause an allergic reaction. Still, metal allergies can be a potential problem within your mouth as with other areas of health.
An allergy originates from the body’s necessary response to potentially harmful microorganisms or substances. Sometimes, however, this response becomes chronic and exaggerated, creating an allergy. People can have allergies to nearly anything with responses ranging from a minor rash to a potentially life-threatening multi-organ system shutdown (anaphylactic shock).
A small number of people have allergies to particular metals. One of the most common is nickel, which affects an estimated 17% of women and 3% of men; cobalt and chromium are also known to cause allergies. Consumer exposure, particularly metal contact with the skin through jewelry or clothing, is the most prevalent, but not the most concerning. That’s reserved for metal allergies related to medical devices like coronary stents or hip and knee prostheses. And in dentistry, there are rare occasions of inflammation or rashes from metal amalgam fillings.
Which brings us to dental implants: the main metal post that’s inserted into the jawbone is usually made of titanium. It’s the metal of choice for two reasons: it’s bio-compatible, meaning the body normally accepts its presence; and it’s osteophilic, which means bone cells readily grow and adhere to it, a major reason for implant durability.
While it’s possible for someone to have an allergy and subsequent reaction to implants with titanium, the occurrences appear to be extremely low. In one study of 1,500 patients, titanium allergies were estimated to be a factor in implant failures in less than 1% of those studied.
Even so, if you have known metal allergies you should make sure your dentist knows. Being aware of all the facts will help them recommend the best tooth replacement choice for you—and hopefully it will be dental implants.
