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.
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.”
Are your teeth cracked, chipped or damaged? If so, a crown from either James S. Cinamon, DMD, PC or Paul J. Hubley, DMD, PC may be just the solution you need to strengthen your damaged teeth and to guard against future damage. Here are four ways a crown from your Framingham, MA dentist can strengthen your teeth.
1. Replace a Large Cavity
Your Framingham, MA dentist can repair small cavities with a simple filling, but for larger cavities, a more durable solution is needed. Depending on the size, location and shape of your cavity, your dentist may want to use a crown instead of a filling to strengthen your teeth and prevent further decay.
2. Protect a Weak Tooth from Breaking
If your tooth is weak or damaged, sometimes even the slightest bump or bite can cause it to break completely. A crown can help prevent this from happening by covering the tooth in order to stabilize it and hold it together.
3. Cover a Tooth After a Root Canal
Has the damage reached all the way down to your tooth root? If so, your Framingham, MA dentist may need to preform a root canal in order to clean out the infection and inflammation. Once this procedure is completed, your dentist will need to give you a new crown in order to help strengthen your tooth and prevent the infection from returning.
4. Anchor a Dental Bridge
Of course, if your tooth is badly damaged, your Framingham, MA dentist may not be able to save it at all. In this case, you have several options available to you, including getting a dental implant to replace the damaged tooth. Dental implants, which consist of a titanium screw connected to a crown, restore the appearance and functionality of your teeth once again.
If your teeth aren't in the best condition anymore, your trusted Framingham, MA dentist may be able to use a crown to restore your smile once again. Call the office of Dr. Cinamon and Dr. Hubley to find out if you might be a good candidate for this important procedure.
