You’re considering dental implants and you’ve done your homework: you know they’re considered the best tooth replacements available prized for durability and life-likeness. But you do have one concern — you have a metal allergy and you’re not sure how your body will react to the implant’s titanium and other trace metals.
An allergy is the body’s defensive response against any substance (living or non-living) perceived as a threat. Allergic reactions can range from a mild rash to rare instances of death due to multiple organ system shutdowns.
A person can become allergic to anything, including metals. An estimated 17% of women and 3% of men are allergic to nickel, while 1-3% of the general population to cobalt and chromium. While most allergic reactions occur in contact with consumer products (like jewelry) or metal-based manufacturing, some occur with metal medical devices or prosthetics, including certain cardiac stents and hip or knee replacements.
There are also rare cases of swelling or rashes in reaction to metal fillings, commonly known as dental amalgam. A mix of metals — mainly mercury with traces of silver, copper and tin — dental amalgam has been used for decades with the vast majority of patients experiencing no reactions. Further, amalgam has steadily declined in use in recent years as tooth-colored composite resins have become more popular.
Which brings us to dental implants: the vast majority are made of titanium alloy. Titanium is preferred in implants not only because it’s biocompatible (it “gets along” well with the body’s immune system), but also because it’s osteophilic, having an affinity with living bone tissue that encourages bone growth around and attached to the titanium. Both of these qualities make titanium a rare trigger for allergies even for people with a known metal allergy.
Still, implant allergic reactions do occur, although in only 0.6% of all cases, or six out of a thousand patients. The best course, then, is to let us know about any metal allergies you may have (or other systemic conditions, for that matter) during our initial consultation for implants. Along with that and other information, we'll be better able to advise you on whether implants are right for you.

If we could go back in time, we all probably have a few things we wish we could change. Recently, Dr. Travis Stork, emergency room physician and host of the syndicated TV show The Doctors, shared one of his do-over dreams with Dear Doctor magazine: “If I [could have] gone back and told myself as a teenager what to do, I would have worn a mouthguard, not only to protect my teeth but also to help potentially reduce risk of concussion.”
What prompted this wish? The fact that as a teenage basketball player, Stork received an elbow to the mouth that caused his two front teeth to be knocked out of place. The teeth were put back in position, but they soon became darker and began to hurt. Eventually, both were successfully restored with dental crowns. Still, it was a painful (and costly) injury — and one that could have been avoided.
You might not realize it, but when it comes to dental injuries, basketball ranks among the riskier sports. Yet it’s far from the only one. In fact, according to the American Dental Association (ADA), there are some two dozen others — including baseball, hockey, surfing and bicycling — that carry a heightened risk of dental injury. Whenever you’re playing those sports, the ADA recommends you wear a high-quality mouth guard.
Mouthguards have come a long way since they were introduced as protective equipment for boxers in the early 1900’s. Today, three different types are widely available: stock “off-the-shelf” types that come in just a few sizes; mouth-formed “boil-and-bite” types that you adapt to the general contours of your mouth; and custom-made high-quality mouthguards that are made just for you at the dental office.
Of all three types, the dentist-made mouthguards are consistently found to be the most comfortable and best-fitting, and the ones that offer your teeth the greatest protection. What’s more, recent studies suggest that custom-fabricated mouthguards can provide an additional defense against concussion — in fact, they are twice as effective as the other types. That’s why you’ll see more and more professional athletes (and plenty of amateurs as well) sporting custom-made mouthguards at games and practices.
“I would have saved myself a lot of dental heartache if I had worn a mouthguard,” noted Dr. Stork. So take his advice: Wear a mouthguard whenever you play sports — unless you’d like to meet him (or one of his medical colleagues) in a professional capacity…
In our constant battle against infectious disease, the “enemy” is often too close for comfort: hospitals and other medical facilities must be ever vigilant against opportunistic infections their patients may contract while in their care.
Dental offices are no exception. Because even the simplest procedure — a dental cleaning, for example — may result in exposure, providers and patients alike face a possible health risk. We must be especially concerned with blood-borne viral infections — spread by person to person contact through blood — the most serious being hepatitis B and C, and HIV/AIDS.
Hepatitis is a viral inflammatory disease that disrupts the critical functions of the liver, particularly as it cleanses and regulates the blood, and cause serious bodily impairment or death. The virus can be transmitted when the blood from an infected person makes its way into the bloodstream of another person, mainly through cuts or a needle injection. Human immunodeficiency virus (HIV) can lead to the chronic condition AIDS that destroys the body’s immune system; it spreads mainly through sexual contact, as well as through person to person blood contact.
The best defense against the spread of these diseases in dental offices or other healthcare settings is to eliminate as much as possible any opportunity for blood-to-blood contact. To accomplish this, all healthcare providers, including dentists, are mandated by federal, state and local authorities to incorporate and follow routine safety precautions. The U.S. Center for Disease Control and Prevention (CDC) issues regularly updated comprehensive guidelines for protocols and procedures to disinfect and sterilize equipment and facilities.
We dentists and our clinical staffs are also mandated by state licensing boards to refresh our knowledge of infection control procedures through continuing education. Such procedures cover every aspect of infection control, from barrier protection — by way of gloves, masks or gowns — to instrument disinfection.
Protecting patients as well as providers from the spread of infection is one of our profession’s highest standards. As a result, incidents of infection among the 170,000 practicing dentists in the United States are rare. You can be assured, then, that we’re taking every precaution to keep you and your family safe from disease when you visit our office.
