EvolutionsinTooth-ColoredFillings

Tooth-colored fillings are just one of the many ways that cosmetic dentistry has evolved over the past few decades. There was once a time where having a cavity treated meant that you would be left with a noticeable metal filling. However, today we have an array of tools and materials available that help make tooth repair more like creating a fine piece of art.

Tooth-colored fillings are made of composite resin, which is a mixture of plastic and glass. Composite resin is not only more aesthetically pleasing, but also better for your teeth than metal fillings. Metal fillings can require your dentist to remove healthy parts of your tooth to create a ledge (undercut) that locks the filling in place. Tooth-colored fillings do not need this undercut to stay in place. In fact, they physically attach, or bond, to natural tooth structure. The procedure is also very simple. We'll apply the composite resin directly to your teeth, sculpt it and then finally harden it with a special light. When you see the results, you will be amazed at how natural and lifelike the restoration appears.

Another advantage of tooth-colored fillings is that they are strong and flexible. When you bite or chew, they will absorb and transfer the forces, just like your natural teeth. Metal fillings are strong, but they are also stiff, which can stress your teeth and make them more susceptible to cracking.

During your examination, we will evaluate if tooth-colored fillings are the best tooth repair option. If your cavity is too large for composite resin, we may recommend a porcelain filling. This procedure may require two appointments: the porcelain filling will be crafted in a dental laboratory, and we will then place this filling at your next visit.

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.

FiveFactsAboutTooth-ColoredFillings

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.
