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.

Nothing beats the form and function of a real tooth—but dental implants come pretty close. That's why they're tops among both dentists and patients for replacing missing teeth.
Much of an implant's functionality and durability can be credited to its material construction, from the titanium metal post imbedded in the jawbone to the lifelike porcelain crown attached at its other end. But an implant's “nuts and bolts” isn't the only reason why this premier dental restoration is so popular: A good portion of their success comes from the adjunct support provided by digital technology.
Without this varied array of computer-based applications used in planning, designing and installing them, implants couldn't produce the level of satisfactory outcomes they currently do. Here then are a few of the high-tech tools dentists use to make sure your implants result in a winning smile.
CBCT scanning. Implant placement requires a high degree of precision often complicated by various anatomical structures like nerves, blood vessels and sinuses within the gums and jaws. Cone Beam Computer Tomography (CBCT) scanners rotate around a patient's head, taking hundreds of digital x-ray images that are then assembled into a 3-D model image. Dentists can view this model from various angles to identify obstacles and better pinpoint the best implant locations.
Digital impressions. Dentists can also create a 3-D digital impression model of the inside of a patient's mouth that can give them views of their current teeth and gums from any angle. This aids in determining the size and type of implant so that it blends seamlessly with remaining teeth. A digital impression can also provide both the dentist and patient a preview appearance of their future smile after treatment.
3-D printed surgical guides. To accurately drill the implant site during surgery, dentists often create a custom-made device called a surgical guide that fits into the patient's mouth during the procedure. Using results from scanning and digital impressions, highly accurate guides can be created with a 3-D printer. This further ensures that the implant will be in the exact best location for the most attractive and functional outcome.
Implantology is as much art as it is science in achieving a beautiful smile. These and other digital tools help make that desirable end a reality.

If you've been dealing with a tooth that needs to be removed—or it's already missing—you may be looking to replace it with a dental implant. And it's a great choice: No other restoration can provide the appearance and function of a real tooth like an implant.
You and your smile are ready for it. The question is, though, are your gums and underlying bone ready? These dental structures play a critical role in an implant's stability and eventual appearance. A problem with them may make placing an implant difficult if not impossible.
An implant requires around 2.0 millimeters of bone thickness surrounding the implant surface for adequate support and to minimize the chances of gum recession. But tooth loss often leads to bone loss that can drop its thickness below this threshold. This can make placing an implant problematic.
Fortunately, though, we may be able to address the lack of sufficient bone through bone grafting. By placing grafting material within the empty socket, we create a scaffold for new bone cells to grow upon. Over time this subsequent growth may be enough to maintain an adequate thickness of bone for an implant to be placed.
The gums may also pose a problem if they've shrunk back or receded from their normal positions, as often happens because of gum disease (which may also have precipitated the tooth loss). Again, grafting procedures can help ensure there's adequate gum coverage for the implant. And healthier gums may also help protect the underlying bone from loss.
There are several techniques for placing gum tissue grafts, depending on how much recession has taken place. One procedure in particular is often used in conjunction with implant placement. A small layer of synthetic collagen material or gum tissue referred to as pa dermal apron is included with the implant when its placed. Settling into the bone socket, this apron helps thicken the gum tissues, as well as preserve the underlying bone.
During your preliminary exams, we'll assess your bone and gum health to determine if we should take any steps like these to improve them. It may add some time to the implant process, but the end result will be well worth it.
