DentalAmalgamContinuestobeaDurableandSafeToothFilling

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.

ChoosingNaturalTooth-ColoredFillingsOverSilver

Cavities used to be nothing to smile about, but thanks to advances in technology, tooth-colored fillings have made repair of decayed teeth so natural, they're invisible. Now you no longer need to feel self-conscious about that unsightly flash of silver when you talk or laugh. While silver amalgam fillings were once the preferred option for tooth restoration filling materials, tooth-colored “composite resins” have gained popularity as a safe and effective alternative to treat new cavities or to replace old silver fillings.

A Better Alternative: Consumer demand for tooth-colored (metal free) restorations as well as the dental profession's desire to preserve as much natural tooth structure as possible has led to the development of special “adhesive” tooth-colored materials. Besides the aesthetic advantages over amalgam fillings, tooth-colored fillings require the removal of less tooth structure. While traditional silver fillings often crack or leak over time, composite resin fillings bond directly to tooth structure and actually reinforce and strengthen it while creating a natural looking smile.

The Choice is Yours: You can choose to replace unsightly silver fillings with tooth-colored ones to enhance their cosmetic appearance. Although concern has been expressed over the mercury content in older silver fillings, years of research cited by the American Dental Association has found that traditional amalgam fillings are safe. Unless you have cracks or damage to your current amalgam fillings or have other concerns regarding your dental health, replacing silver fillings is a matter of personal preference.

Cost: Although composite resin fillings may cost slightly more than silver fillings, they are very durable and may be more cost-effective in the long run.

FrequentlyAskedQuestionsAboutTooth-ColoredFillings

Are tooth-colored fillings safer than silver fillings?
No. Both are considered safe based on the most reliable and up-to-date scientific evidence. Still, tooth-colored fillings do have some definite advantages. Not only do they blend in with your smile far better than “silver” (dental amalgam) fillings, but they often require less removal of healthy tooth structure. That’s because in order to fill a tooth with amalgam, it is necessary to create indentations in the tooth called “undercuts” to hold the amalgam in; this requires the removal of some healthy tooth material. With a tooth-colored filling, we need only remove the decayed part of the tooth to place the filling.

Are there any disadvantages?
Yes, tooth-colored fillings don’t always wear as well as metal fillings — particularly on back molars where they are subjected to the most stress from chewing. They are also more expensive and less likely to be fully reimbursed under dental insurance plans.

Are there different types of tooth-colored fillings?
Yes, three different choices of tooth-colored fillings are available:

  • Composite — This mixture of plastic and glass is the most common type of tooth-colored filling. Newer materials can hold up almost as long as amalgam fillings and look very natural, though they can stain over time just as natural teeth do.
  • Porcelain — High-tech dental ceramics are considered the most aesthetic choice of filling material. They don’t stain as composites can, but their relatively high glass content can make them more brittle and prone to breakage. They may be more expensive than composites.
  • Glass Ionomer — Made of acrylic and glass powders, these inexpensive, translucent fillings blend in acceptably well with natural teeth and have the advantage of releasing small amounts of fluoride to help prevent decay. However, they generally don’t last as long as other restorative materials.

We would be happy to offer guidance on which choice would be best in your own unique situation.
