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.

One in ten Americans has diabetes, a serious condition that may increase the development and severity of other health problems—including gum disease. Because of this latter connection, dental providers join other health professionals during November's National Diabetes Month to call attention to this chronic disease and its effect on health and well-being.
There's another health condition with a diabetes connection that isn't as well known: obstructive sleep apnea (OSA). It's also of keen interest to dental providers, as dentists are often involved in the discovery and treatment of this common sleep disorder.
OSA is the temporary blockage of the airway during sleep by the tongue or other anatomical structures. The subsequent drop in oxygen awakens the body to remove the obstruction. People with OSA may not realize they have the condition, but their bed partner can often attest to their snoring, snorting and gasping for breath during the night. Such episodes can occur several times per night, depriving the person of sufficient sleep.
Chronic OSA can contribute to the development of other health problems, among them Type 2 diabetes. It can do this first by interfering with the metabolization of glucose (blood sugar). It may also increase the body's resistance to insulin, the primary hormone regulating glucose.
Fortunately, properly managing OSA can lower your risk for diabetes, and that's where dentists may be able to help. For one thing, we dentists are often the first to notice early signs of OSA—sometimes even before our patients do.
According to the American Sleep Apnea Association, as many as 80% of the estimated 22 million Americans with OSA may not know they have it. But dentists often identify OSA indicators while examining patients: signs like an enlarged tongue or tonsils, or patients falling asleep in the exam chair. While we can't formally diagnose OSA, we often refer symptomatic patients to a sleep specialist.
Dentists also offer an alternative to the most common OSA therapy, which is continuous positive airway pressure (CPAP). This therapy employs a motorized pump that delivers pressurized air into the throat via face mask to keep the airway open during sleep. Although effective, some people find a CPAP machine noisy and uncomfortable to use.
Alternatively, dentists can provide an oral device that can often help patients with mild to moderate OSA that's worn in the mouth during sleep. Most of the various types of these appliances either reposition the lower jaw with a hinge mechanism to keep the throat open or pull the tongue away from the airway through a suction effect.
Diabetes is one part of a chain reaction that can bring unexpected challenges to your health, including to your teeth and gums. You can slow or even stop its development with proper diet, exercise and good, restful sleep. Dealing with OSA is often part of that equation—and we may be able to help.
