Recently, a number of new filling materials that mimic tooth color have come into popular use and, so far, have proven more durable than past versions. Even so, the traditional metal-based dental amalgam remains a viable choice, especially for less visible back teeth and their higher biting forces.
Used for more than a century, dental amalgam is a metal alloy composed of silver, mercury, tin and copper. The mixture is carefully proportioned so that potentially hazardous mercury is kept to a minimum and bonded with the other metals. Amalgam in its initial form is quite pliable so that it can be molded into the tooth structure under repair. Afterward it sets hard to form a durable filling that can withstand the daily force generated when we bite and chew food.
Besides durability, dental amalgam rarely causes an allergic reaction in a patient, and it’s easy for trained dentists to apply. On the downside, however, it can cause temporary temperature sensitivity in the tooth just after filling, and the tooth itself may require some removal of healthy structure to help keep the filling in place. And from an aesthetic point of view, its metallic appearance is considered unattractive especially for front teeth.
The presence of mercury in amalgam has also raised concerns over the years. “Free” mercury — atoms that escape through vapor emitted by the metal — can enter the bloodstream and potentially harm the nervous system. But after extensive study and research, U.S. and international health bodies including the American Dental Association have concluded any free mercury released during chewing is extremely low and well below any harmful levels. These studies have also found no ill effects in either children or adults with dental amalgam fillings.
Deciding on the type of filling material to use — dental amalgam or a newer composite resin, resin ionomer or glass ionomer — depends on a number of factors including the location of the teeth to be filled, the extent of decay and your personal preferences. Taking these into account, we’ll be happy to discuss which type of filling will suit you best for repairing decayed teeth.

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.

Our main focus as your dentist is to keep your teeth and gums healthy and functional. But there’s another important aspect of care — your teeth’s appearance. It’s not just a superficial concern: your smile can have a profound effect on your self-image, as well as your personal and professional relationships.
This is the realm of cosmetic dentistry: served by both specialists and general dentists, it focuses on altering your teeth’s appearance with treatments as basic as teeth whitening or as comprehensive as dental implants. The goal, however, is the same: a new, more attractive smile.
In a way, cosmetic dentistry begins with you and oral hygiene. The twin tasks of brushing and flossing to remove dental plaque not only lowers your risk for tooth decay or periodontal (gum) disease, they also improve the appearance of the tooth surface. There are, however, circumstances where otherwise healthy or repaired teeth may need extra cosmetic attention due to chipping, misshape or staining. In these cases, a truly cosmetic approach may be necessary.
One approach is to cover a tooth’s blemishes. Veneers, for example, are thin, layered pieces of dental porcelain shaped and colored like natural teeth that are bonded to the outside of an unattractive tooth. In other cases, a tooth may require a life-like porcelain crown that completely covers it to gain the same effect.
Missing teeth, of course, pose a different challenge, but here there are a wide range of solutions: dental implants, fixed bridgework or removable full or partial dentures. Advancements in dental materials and techniques can produce new teeth that are so life-like and natural that they’re imperceptible from the real thing.
Â These and other measures like orthodontics can all be used to turn a smile you find embarrassing into one you’re confident to share with the world. It begins, though, with both you and us taking a good, close look at your current smile — a smile analysis, if you will.
After assessing both your current needs and your expectations for change, we can develop an appropriate treatment plan. It might be quite simple or with multiple treatment stages, but it will be the best plan for you. Through cosmetic dentistry we have the means to help you achieve a new, more confident smile.
