HerearetheFactsontheImpactofMetalAllergiesonDentalWork

Allergic reactions aren't necessarily bad: they're your body's responses to possible threats from foreign substances. But the response can go too far and cause a reaction as minor as a skin rash or as life-threatening as a multi-system shutdown called anaphylaxis.

Anything can cause an allergy: animal fur, food, chemicals — or metals. Because metals play such a large role in dental care, it's only natural we're alert to the possibility of allergic reactions from a procedure.

But don't postpone your implants or other dental work just yet — the threat isn't nearly that ominous. Here are a few facts about dental metal allergies to help you sort it out.

Allergic reactions are rare for metals used in medical and dental procedures. Although reactions to metals in joint replacements or coronary stents leading to failure do happen, actual occurrences are rare. Most metal allergies manifest as a skin reaction to jewelry or clothing. It's less likely with medical or dental metals because they're chosen specifically for their compatibility with living tissue.

Amalgam fillings account for most dental work reactions. Dentists have used this multi-metal alloy for fillings and other restorations for well over a century. Tooth-colored resins are now used for most fillings, but amalgam is still used in less visible back teeth. It's very rare for a person to experience a reaction to amalgam, but when it does occur it usually results in minor inflammation or a rash.

Implant titanium isn't just bio-compatible — it's also osteophilic. Titanium is the perfect choice for implants not only because it's tissue friendly, but also because it's bone friendly (osteophilic). Once implanted in the jaw, bone cells naturally grow and adhere to it to create a more durable bond. Not only does the body usually tolerate titanium, it welcomes it with open arms!

While it's still possible for you to have an allergy to implant titanium, the chances are remote. In one recent study involving 1,500 implant patients, titanium allergies occurred in less than 1%. So the chances are high a metal allergy won't stop you from obtaining a smile-transforming restoration with dental implants.

Let’s say you’re traveling to Italy to surprise your girlfriend, who is competing in an alpine ski race… and when you lower the scarf that’s covering your face, you reveal to the assembled paparazzi that one of your front teeth is missing. What will you do about this dental dilemma?

Sound far-fetched? It recently happened to one of the most recognized figures in sports — Tiger Woods. There’s still some uncertainty about exactly how this tooth was taken out: Was it a collision with a cameraman, as Woods’ agent reported… or did Woods already have some problems with the tooth, as others have speculated? We still don’t know for sure, but the big question is: What happens next?

Fortunately, contemporary dentistry offers several good solutions for the problem of missing teeth. Which one is best? It depends on each individual’s particular situation.

Let’s say that the visible part of the tooth (the crown) has been damaged by a dental trauma (such as a collision or a blow to the face), but the tooth still has healthy roots. In this case, it’s often possible to keep the roots and replace the tooth above the gum line with a crown restoration (also called a cap). Crowns are generally made to order in a dental lab, and are placed on a prepared tooth in a procedure that requires two office visits: one to prepare the tooth for restoration and to make a model of the mouth and the second to place the custom-manufactured crown and complete the restoration. However, in some cases, crowns can be made on special machinery right in the dental office, and placed during the same visit.

But what happens if the root isn’t viable — for example, if the tooth is deeply fractured, or completely knocked out and unable to be successfully re-implanted?

In that case, a dental implant is probably the best option for tooth replacement. An implant consists of a screw-like post of titanium metal that is inserted into the jawbone during a minor surgical procedure. Titanium has a unique property: It can fuse with living bone tissue, allowing it to act as a secure anchor for the replacement tooth system. The crown of the implant is similar to the one mentioned above, except that it’s made to attach to the titanium implant instead of the natural tooth.

Dental implants look, function and “feel” just like natural teeth — and with proper care, they can last a lifetime. Although they may be initially expensive, their quality and longevity makes them a good value over the long term. A less-costly alternative is traditional bridgework — but this method requires some dental work on the adjacent, healthy teeth; plus, it isn’t expected to last as long as an implant, and it may make the teeth more prone to problems down the road.

What will the acclaimed golfer do? No doubt Tiger’s dentist will help him make the right tooth-replacement decision.

If you have a gap in your grin — whatever the cause — contact us or schedule an appointment for a consultation, and find out which tooth-replacement system is right for you. You can learn more in the Dear Doctor magazine articles “Dental Implant Surgery” and “Crowns & Bridgework.”
