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.

It used to be that when it came to treating tooth decay (cavities), your primary option was to have the tooth decay removed and filled with a metal amalgam (silver-colored filling). This treatment sometimes requires a special shape cut called an “undercut” to be drilled into the tooth to hold it in. Unfortunately, it can also involve removal of some healthy tooth structure. Silver amalgam fillings still have limited applications and are still used in back teeth where they don't show in the smile. This is because they are strong and resist biting well; however, over time they can fatigue and fracture.

Older restorative concepts were based upon the development of strong and stiff materials such as gold, which tends to be unyielding and therefore contributed to failures of the remaining tooth substance around restorations (e.g., decay or cracking). Newer concepts tend to get away from the “stronger and stiffer is better” concept and have moved towards safety principles using materials that involve mimicking the properties of natural tooth structure. In fact, it is now clearly established that a new “biomimetic approach” (“bio” – life; “mimetic” – mimicking) to dentistry is possible through the use of tooth-like materials such as composite resins and porcelains. And unlike metal alloys, these newer materials bond directly to the remaining enamel and dentin of which the teeth themselves are made, which both stabilize and strengthen teeth.

These techniques are also suitable for children's teeth and can incorporate fluoride to reduce further decay. But perhaps best of all, using these materials and more modern technologies can restore proper tooth function and normal wear while producing results that appear indistinguishable from natural teeth.
