For decades, dental amalgam — the common “silver” fillings found in the mouths of millions — was the best option for restoring teeth after the removal of decay. This time-tested material is still going strong, but in recent years it's had serious competition from newer restoration techniques that use tooth-colored substances to make fillings. If you've heard of these new materials and want to know more, you can start with the following five facts.
1) Filling materials must match the properties of natural teeth.
When properly cared for, teeth are strong, resilient, and superbly functional. A good filling material should mimic the strength and durability of natural teeth under biting forces. It should also last a long time in the mouth, be relatively easy to place, and be economical in cost. In the past, amalgam fillings were the best choice to do the job. But that was then.
2) Tooth-colored filling materials offer similar benefits, plus aesthetic appeal.
Composite resins and dental porcelains are tough, durable materials that have been found to hold up well under years of use. Unlike traditional silver fillings, however, they match the appearance of natural teeth quite closely. This means that even a restoration in the front of the mouth may be virtually undetectable. And who wouldn't like that?
3) Tooth-colored resins may allow more conservative treatment in decay removal.
In order to keep them securely in place, amalgam (silver) fillings may require “undercutting,” which removes more of the tooth structure. The process involved in bonding tooth-colored restorations, however, generally requires removal of less tooth material. This means a stronger base for rebuilding the tooth's structure.
4) Different treatment methods are used for different degrees of tooth restoration.
Small cavities can be treated by direct “chairside” techniques, which are very similar to the methods used for traditional amalgam (silver) fillings: in one brief visit, it's all done. When a greater volume of tooth structure must be replaced, we may be able to create a larger tooth-colored filling in a longer visit. Or, we might need to have a special restoration made to match your teeth; then, you can come back to have it securely bonded for a natural and long-lasting result.
5) Both amalgam and tooth-colored fillings are safe and effective.
Each has advantages and disadvantages in particular cases. But as the technology of tooth-colored filling systems evolves, some dental researchers have heralded the beginning of the “post-amalgam era.” Are tooth-colored fillings right for your individual situation? We're the ones to ask.
