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.

After years battling disease, your troubled tooth reached its useful life's end. It's been extracted, and we've replaced it with a life-like dental implant. So now, as far as the implant goes, disease is no longer an issue…right?
Sorry, no—though not to the same degree as a natural tooth, an implant could be endangered by gum disease. Although the implant's materials can't be infected, the supporting gums and bone can.
In fact, there's a particular type of gum disease associated with implants known as peri-implantitis (“peri” around an implant; “itis” inflammation) that first affects the gums surrounding an implant. Although peri-implantitis can arise from an excess of dental cement used to affix the crown to the implant, it most commonly starts like other forms of gum disease with dental plaque.
Dental plaque, and its hardened form calculus (tartar), is a thin, bacterial biofilm that builds up on teeth surfaces. It can quickly accumulate if you don't remove it every day with proper brushing and flossing. The bacteria living in plaque can infect the outer gum tissues and trigger inflammation.
Gum disease around natural teeth can spread quickly, but even more so with implants. That's because the natural attachment of the gums helps supply antibodies that impede infection. Implants, relying solely on their connection with the bone, don't have those gum attachments. As a result, peri-implantitis can move rapidly into the supporting bone, weakening the implant to the point of failure.
The good news, though, is that peri-implantitis can be treated successfully through aggressive plaque removal and antibiotics. But the key to success is to catch it early before it progresses too far—which is why you should see your dentist at the first sign of gum swelling, redness or bleeding.
You can also prevent peri-implantitis by practicing daily brushing and flossing, including around your dental implant. You should also see your dentist twice a year (or more, if they advise) for cleanings and checkups.
Dental implants overall have a greater than 95% success rate, better than any other tooth restoration system. But they still need daily care and regular cleanings to ensure your implants are on the positive side of those statistics.
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.

You would love to replace a troubled tooth with a dental implant. But you have one nagging concern: you also have diabetes. Could that keep you from getting an implant?
The answer, unfortunately, is yes, it might: the effect diabetes can have on the body could affect an implant's success and longevity. The key word, though, is might—it's not inevitable you'll encounter these obstacles with your implant.
Diabetes is a group of metabolic diseases that interfere with the normal levels of blood glucose, a natural sugar that is the energy source for the body's cells. Normally, the pancreas produces a hormone called insulin as needed to regulate glucose in the bloodstream. A diabetic, though either can't produce insulin or not enough, or the body doesn't respond to the insulin that is produced.
And while the condition can often be managed through diet, exercise, medication or supplemental insulin, there can still be complications like slow wound healing. High glucose can damage blood vessels, causing them to deliver less nutrients and antibodies to various parts of the body like the eyes, fingers and toes, or the kidneys. It can also affect the gums and their ability to heal.
Another possible complication from diabetes is with the body's inflammatory response. This is triggered whenever tissues in the body are diseased or injured, sealing them off from damaging the rest of the body. The response, however, can become chronic in diabetics, which could damage otherwise healthy tissues.
Both of these complications can disrupt the process for getting an implant. Like other surgical procedures, implantation disrupts the gum tissues. They will need to heal; likewise, the implant itself must integrate fully with the bone in which it's inserted. Both healing and bone integration might be impeded by slow wound healing and chronic inflammation.
Again, it might. In reality, as a number of studies comparing implant outcomes between diabetics and non-diabetics has shown, there is little difference in the success rate, provided the diabetes is under control. Diabetics with well-managed glucose can have success rates above 95%, well within the normal range.
An implant restoration is a decision you should make with your dentist. But if you're doing a good job managing your diabetes, your chances of a successful outcome are good.
