Tooth-ColoredFillingsANatural-LookingAlternative

Once upon a time, when you had a cavity, you went to the dentist and came back with a tooth filled with metal: the common silver (or, technically speaking, “dental amalgam”) filling. But today — driven by dental researchers' quest to find a better filling material, and by the desire of many people to avoid a mouth full of dull gray metal — there are other choices.

In recent years, metal-free, tooth-colored fillings have evolved into a well-established treatment method that's finding increasing use — not just in the front of the mouth, where it's most visible, but in the back too. To help understand the benefits of these new materials, let's start by looking at the structure of the tooth.

We usually think of teeth as being hard, sturdy and durable. But did you know that their crowns, or top surfaces above the gums, actually flex under the force of the bite? Understanding the composition and behavior of teeth has led researchers to develop newer and better materials for restoration. These include improved dental porcelains and composite resins which more closely mimic the natural teeth in both function and form: That is, they're strong and good-looking too.

What's more, using these materials for fillings may mean that you can get the same result with a more conservative treatment. How? It all comes down to tooth structure. To secure a traditional amalgam (silver) filling, a tooth often had to be shaped with “undercuts,” which helped hold the material in place. This meant the removal of a greater amount of tooth structure, potentially leading to chipping or cracking of the tooth down the road.

Enter composite resins. Bonding these materials to the underlying tooth doesn't require undercutting, so less of the healthy tooth is removed. That makes for a more robust tooth structure, with potentially greater longevity. Combine that advantage with the aesthetic appeal of a restoration that's hard to tell apart from natural teeth, and you've got a winning combination.

There are different options available for restorations with tooth-colored materials. These range from quick, single-visit fillings for small cavities, to the fabrication of more extensive replicas of the tooth for complicated restorations. Exactly which treatment is needed will depend on an individual's particular dental issue and the kind of results they desire. Whatever the case may be, we can listen to your concerns, answer your questions, and offer the best advice regarding your treatment options.

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.
