The subject of allergies covers a wide swath in medicine. Among other things, people have allergic reactions to animal fur, various foods and plant pollen. The effects are equally wide-ranging, anything from a mild rash to anaphylaxis, a life-threatening shutdown of the body's vital systems.
Approximately 5% of people are also allergic to various metals including nickel, cobalt, chromium and gold. Reactions to metal can occur when an allergic person comes in contact with items like jewelry, clothing or even mobile phones. There's even a chance of a metal allergy reaction from certain kinds of dental work.
It's unlikely, though, that you should be concerned if you're considering dental treatment or cosmetic work to upgrade your smile. Although allergic reactions like inflammation or a rash have been known to occur with amalgam “silver” fillings, it's quite rare. It's even less of a concern since “tooth-colored” materials for fillings are now outpacing the use of amalgam fillings, which are used in out-of-sight back teeth.
Of course, metal is used for other dental treatments besides fillings, including the most popular of tooth replacement systems, dental implants. An implant is essentially a metal post, usually made of pure titanium or a titanium alloy, which is imbedded into the jawbone. Even so, there's little chance you'll develop an allergic reaction to them.
For one thing, titanium is highly prized in both medical and dental treatments because of its biocompatibility. This means titanium devices like prosthetic joints and implants won't normally disrupt or cause reactions with human tissue. Titanium is also osteophilic: Bone cells readily grow and adhere to titanium surfaces, a major reason for dental implants' long-term durability.
That's not to say titanium allergies don't exist, but their occurrence is very low. One recent study detected a titanium allergy in only 0.6% of 1,500 implant patients who participated.
At worst, you may need to consider a different type of tooth replacement restoration in the rare chance you have a titanium allergy. More than likely, though, you'll be able obtain implants and enjoy the transformation they can bring to your smile.

Complete tooth loss is a common condition among older adults, gradually occurring one or two teeth at a time. There often comes a point of realization, though, that all the teeth will eventually be lost.
This can create a dilemma: Do you replace teeth as they're lost, or go ahead and have all of them removed at one time?
Up until recently, the latter choice seemed the most practical and affordable. But most dentists would agree that keeping natural teeth for as long as practical is better for a person's overall oral health and to slow any potential bone loss.
The emergence of dental implants has made this less of a dilemma: We can use this technology to more affordably replace teeth in stages rather than all at once. This is because an implant is technically a root replacement: a dentist inserts a titanium metal post into the jawbone. Because of an affinity with titanium, bone cells grow and adhere to the implant surface, which creates a stronger hold. It also impedes bone loss.
We can, of course, use implants as individual tooth replacements. But the expense of this approach with multiple teeth puts it well out of reach financially for many people. But implants can also be used as connective points between the patient's jaw and other kinds of dental restorations like bridges, partial dentures, and full removable or fixed dentures.
Using this approach, we can adopt a strategy of allowing healthier teeth to remain until it's necessary to remove them. We initially place implants to support a bridge, for example; later we can use the same implants along with additional ones to support a larger restoration, even a fixed full denture.
An implant-supported restoration is typically more expensive than traditional bridges or dentures, but far less than replacing teeth with individual implants. And because the stages of restorations may occur over a long period of time, the cost can be spread out to make it more manageable.
If you're facing a future where it's likely you'll lose all your teeth, you don't have to lose them all at once. Staged restorations with implants could help you hold on to your natural teeth for as long as possible, slow bone loss and make for a healthier mouth.

Compared to other dental restorations—a few of which have been around for over a century—implants are a relatively recent development. But even though it's just now entering its fourth decade, recent advances have catapulted implant therapy well beyond where it began.
That's due mainly to digital technology. Two examples of this, computed tomography (CT) and 3-D printing, are increasing the accuracy and efficiency of implant placement.
Properly placing an implant is one of the most important elements in achieving a natural and attractive result. But finding the best location is often difficult due to a lack of suitable bone volume, the patient's bite or the proximity of anatomical structures like nerves and blood vessels. CT imaging, especially Cone Beam CT scanners (CBCT), is helping to make implant placement planning easier.
Unlike the static, two-dimensional views of standard x-rays, CBCT takes hundreds of images and digitally blends them together to create a virtual 3-D model of the patient's jaw and face. Dentists can view this highly detailed model on a computer monitor from various vantage points and better identify possible obstructions. With better information about what "lies beneath," they can more accurately pinpoint the best implant site.
Creating the ideal plan is one thing—successfully implementing it is another. Dentists often create a surgical guide that helps them drill in precisely the right positions during surgery. The guide, which resembles a mouthguard, fits over the gums and contains marker locations for drilling.
Many dentists are now using 3-D printing to create these surgical guides. A 3-D printer turns a digital model of the guide based on measurements of the patient's mouth and proposed implant locations into an actual physical object "printed out" layer by layer of special polymer material. The end product can be more precise than guides created by other means.
These and other technological developments are helping implant therapy rise to a new level of success. With the resulting increase in accuracy, efficiency and less treatment time, tomorrow's implant patients will be the ultimate beneficiaries.

This is the story of a well-known man, fearless in most respects, who was afraid of the dentist. Even though his fears had resulted in neglect and serious damage to his teeth, modern dentistry and a talented dental team were able to restore his smile to health. If you share this fear, his story may inspire you to take action.
We're talking about William Perry, former defensive lineman and fullback for the Chicago Bears. Here is a man who could fearlessly face a football squad — but not a visit to the dentist. Nicknamed “The Refrigerator” for his 380-pound massive frame, Perry played for ten years in the NFL before retiring in 1994. Since retiring he founded and operated a construction company in South Carolina in addition to making celebrity appearances.
With his celebrity in mind, a team composed of a talented restorative dentist, implant surgeon, and lab technician agreed to give “The Fridge” a makeover. After discussing modern technology and virtually pain-free dentistry with him, they managed to overcome Perry's fears. “I had been in constant pain for many years and I neglected myself, not having had any dental care for over 20 years, not even emergency care. Unfortunately, as I grew older my teeth started to get loose,” Perry told an interviewer. He had lost many teeth and became known for his gap-toothed smile.
Perry had severe gum disease and many of his remaining teeth were loose. In the past his only option would have been a full set of dentures. But his new dental team was able to place dental implants (permanent tooth replacements) supporting fixed bridges. In most cases dental bridges are attached to healthy teeth, but in Perry's case the implants served as anchors for the bridges. They also stabilized his jawbone, which would otherwise “resorb” or melt away after his teeth were lost. This is important because it helps preserve the contours of his face.
After careful planning “The Fridge” had eight dental implants placed in his upper jaw and seven in his lower. The final bridgework was completed four months later. It turned out that even though the gap between his teeth had become his trademark, “the Fridge” never really liked it. He was thrilled with his new smile.
Even if you have some fears, don't hesitate to follow Perry's example and make an appointment with us for a consultation about dental implants, smile makeovers, or bridgework.
