AlthoughRareAllergicReactionstotheMetalinImplantsCouldbeaConcern

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 you would like more information on the effects of metal allergies on dental implants, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “Metal Allergies to Dental Implants.”

HughJackmansShockingTeeth

Australian heartthrob Hugh Jackman has won international recognition for his work on stage, screen and television, including his long-running portrayal of Wolverine in the X-Men film series, and his Academy-Award-nominated starring role in Les Miserables. Oh, and did we mention he was named the “sexiest man alive” by People magazine in 2008? So when Jackman once said “I have shocking teeth”… what did he mean?

“[My dentist] looked at my teeth and went, ‘Oh, my God, you've got gray teeth,’” the actor stated. The proposed cure: tooth whitening. But what if the action hero's teeth were brightened too much — would his look still convey his trademark rugged charm? To see how that issue was resolved, let's look a little closer at various methods of tooth whitening.

All Whitening Isn't the Same
Everyone has seen the kind of over-the-counter tooth whitening strips advertised in magazines and sold in drug stores. Most dentists agree that, given enough time, they can work in many cases. But there may be problems, too.

One is that unless you know what's actually causing the darkening, you can't be sure if there is an underlying issue that needs treatment — a root-canal problem, for example. Bleaching a diseased tooth is like painting over a rusty car: it camouflages the problem, but doesn't fix it. That's one reason why, before any whitening treatment is attempted, it's important to have a complete dental examination, with x-rays.

Another is that without professional supervision, it's more difficult to control the degree of whitening you will end up with. For safety reasons, over-the-counter whitening products have the least concentrated bleaching agent, and will probably require weeks of use to produce noticeable results. The next step up — a custom-designed, at-home bleaching kit from our office — will likely produce results twice as fast.

The Professional Advantage
At-home bleaching done under our supervision uses stronger whitening agents with a flexible plastic tray that's custom-made to fit your teeth. It's a cost-effective way to achieve several shades of whitening in a relatively short time. Plus, with the advantage of our experience and guidance, you can get excellent results safely and efficiently.

If you want the fastest and most controllable whitening, however, in-office whitening treatments are the best way to go. According to one study, using the most concentrated whiteners in a safe clinical setting produced a six-shade improvement in just three office visits! This would have required a week or more of at-home bleaching, or upwards of 16 daily applications of the over-the-counter whitening products!

In-office whitening also offers the greatest degree of control over the outcome. That's why it was the method Hugh Jackman chose for his treatments. By adjusting the concentration of the bleaching solution and the treatment time, Jackman's dentist made sure his teeth were pleasingly light — but still looked completely natural. And in our office, we can do the same for you.

So whether you're looking for a dazzlingly bright smile or a more subtle enhancement, the best way to start is to call our office for a consultation. For more information, see the Dear Doctor magazine articles “Important Teeth Whitening Questions Answered” and “Teeth Whitening.”
