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.

Do you have silver dental fillings that you wish you didn't have? Wouldn't it be nice if no one could look in your mouth and see how many cavities you had as a kid? Tooth-colored fillings may offer a solution to the problem of too much metal in your mouth. How much do you really know about non-metallic tooth-colored fillings? Take our quiz and find out.
True or false: Tooth-colored fillings are a radical new technology.
False. A variety of dental porcelains and composite resins have been successfully used in tooth restoration for many years. These materials have been designed to mimic the properties of the two major components of teeth: the hard outer enamel, and the bone-like inner dentin. Our increasing understanding of tooth structure and composition has led to better and more natural-looking filling substances.
True or false: Teeth must remain rigid under the pressure of the bite.
False. At one time, metal amalgam (silver) fillings were preferred because of their extreme hardness. But we now know that the crowns of our teeth actually flex under the forces of the bite. This discovery has spurred the development of new methods and materials to stabilize the restored tooth and reduce the incidence of premature failure.
True or false: It's usually more complicated to put in a tooth-colored filling than a metal one.
False. Regardless of which material is used, the basic process of filling a tooth is the same. The dentist prepares the tooth for treatment, removes decay, and places a filling directly into the tooth. If the filling is moderately deep, a tooth-colored filling may be set in several layers which are successively “cured” or hardened. More extensive restorations may require more than one visit, but the natural-looking results generally justify the extra time.
True or false: Regular metal fillings make the tooth structure stronger.
False. Properly securing an amalgam filling may require the tooth to be “undercut,” meaning that a greater amount of healthy tooth material must be removed. This can weaken the tooth structure, eventually leading it to chip and crack. Non-metallic fillings don't require undercutting, so more tooth structure is left intact. This more conservative treatment can result in a stronger, longer-lasting restoration.
True or false: Non-metallic (tooth-colored) fillings are safer than silver fillings.
False. While each method has advantages and disadvantages, and may not be an appropriate treatment in every situation, both methods have been deemed safe and effective by major U.S. and international science and health organizations. While there have been recent concerns about mercury in amalgam fillings, there is presently no reason to believe that it presents any cause for concern.
