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-ColoredFillingsTrueorFalse

Do you have silver dental fillings that you wish you didn't have? Wouldn't it be nice if no one could look in your mouth and see how many cavities you had as a kid? Tooth-colored fillings may offer a solution to the problem of too much metal in your mouth. How much do you really know about non-metallic tooth-colored fillings? Take our quiz and find out.

True or false: Tooth-colored fillings are a radical new technology.

False. A variety of dental porcelains and composite resins have been successfully used in tooth restoration for many years. These materials have been designed to mimic the properties of the two major components of teeth: the hard outer enamel, and the bone-like inner dentin. Our increasing understanding of tooth structure and composition has led to better and more natural-looking filling substances.

True or false: Teeth must remain rigid under the pressure of the bite.

False. At one time, metal amalgam (silver) fillings were preferred because of their extreme hardness. But we now know that the crowns of our teeth actually flex under the forces of the bite. This discovery has spurred the development of new methods and materials to stabilize the restored tooth and reduce the incidence of premature failure.

True or false: It's usually more complicated to put in a tooth-colored filling than a metal one.

False. Regardless of which material is used, the basic process of filling a tooth is the same. The dentist prepares the tooth for treatment, removes decay, and places a filling directly into the tooth. If the filling is moderately deep, a tooth-colored filling may be set in several layers which are successively “cured” or hardened. More extensive restorations may require more than one visit, but the natural-looking results generally justify the extra time.

True or false: Regular metal fillings make the tooth structure stronger.

False. Properly securing an amalgam filling may require the tooth to be “undercut,” meaning that a greater amount of healthy tooth material must be removed. This can weaken the tooth structure, eventually leading it to chip and crack. Non-metallic fillings don't require undercutting, so more tooth structure is left intact. This more conservative treatment can result in a stronger, longer-lasting restoration.

True or false: Non-metallic (tooth-colored) fillings are safer than silver fillings.

False. While each method has advantages and disadvantages, and may not be an appropriate treatment in every situation, both methods have been deemed safe and effective by major U.S. and international science and health organizations. While there have been recent concerns about mercury in amalgam fillings, there is presently no reason to believe that it presents any cause for concern.

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.

HowModernDentalFillingsMimicRealTeeth

Until recently anyone who needed to repair cavities in his or her teeth ended up with a mouth full of “silver” fillings. Dental amalgam, which has a silver appearance, was the tooth restoration material of choice. Amalgam, a combination of metals including silver, mercury, and other metals, is still used — but today there are other options that mimic the original teeth they are restoring.

You may have read about some people's concerns about the mercury used in dental amalgam. According to the American Dental Association (ADA), scientific studies have found no ill effects arising from using dental amalgam in fillings for adults or children: “While questions have arisen about the safety of dental amalgam relating to its mercury content, the major US and international scientific and health bodies, including the National Institutes of Health, the US Public Health Service, the Centers for Disease Control and Prevention, the Food and Drug Administration and the World Health Organization, among others have been satisfied that dental amalgam is a safe, reliable and effective restorative material.” Dental amalgam is still used for molars (back teeth) that must withstand heavy pressure from chewing.

For teeth that are more visible, materials that look and perform more like the original teeth — and are thus more pleasing in appearance — are now available. Dentistry is now taking a “biomimetic approach” (from words meaning “life mimicking”). The new materials — composite resins and porcelains — look like teeth because in many ways their structure imitates the biologic structure of teeth.

Composite resins are made of a plastic material (methacrylate) combined with fillers made of silica, a form of glass. They are able to bond to natural tooth structure and resemble the dentin, the inner layer of the tooth, which has a porous structure similar to bone.

Dental porcelains are a form of ceramic. They are non-metallic materials formed by the action of heat, like the ceramics used in porcelain cups and bowls. They come in a powder form that is mixed with water, shaped, and then placed in an oven until they reach the proper hardness. The end product is translucent and very hard, resembling the densely packed crystals of calcium that make up a tooth's normal outer layer, the enamel.

The old amalgam fillings required removal of tooth material to prepare a site in which they could be placed. Composite resins and porcelains can be used to treat teeth that have small or large amounts of damage to their natural substance because the materials bond directly to the remaining dentin and enamel. Thus they end up stabilizing and strengthening the restored tooth, as well as providing a natural-looking appearance.

AreTooth-ColoredFillingsRightforYou

When you say “ahhhhh,” are you worried about all your unsightly metal fillings? If so, did you know that your dentist can resolve your concerns through the use of tooth-colored fillings?

The public's demand for aesthetic tooth-colored (metal free) restorations (fillings) together with the dental profession's desire to preserve as much natural tooth structure as possible has led to the development of special adhesive tooth-colored restorations. And the demand is not limited to just the front teeth. In fact, many people are opting to replace all of their metal fillings — not just those in the front teeth — so that all of their teeth appear younger, fresher and as if they have never had any cavities.

Can you really mimic natural teeth? Proper tooth restoration is a lot more than just filling holes. It is a unique art applied with scientific understanding. Each tooth's internal shape and structure is the guide to how it must be rebuilt to successfully restore it. However, choosing which material to use to restore or rebuild teeth is a critical one based on scientific understanding, experience and clinical judgment — expertise we use daily in our office. The most popular options include composite resins and porcelains, as they allow us to mimic natural tooth colors and shapes. But for the most life-like, natural tooth-colored filling, your best option is porcelain. Porcelain, which is built up in layers, can be made to mimic the natural translucency and contours of tooth enamel.

But what about matching the color? Will it really match? Absolutely! Whether we use resins or porcelain, through our artistry we will create absolute tooth-like replicas. You will never know your teeth have fillings! And unlike metal alloys, these newer materials bond directly to the remaining enamel and dentin of which the teeth themselves are made, thus stabilizing and strengthening them. These techniques are even suitable for children's teeth and can incorporate fluoride to reduce decay.

Still undecided? If so, we understand. Feel free to contact us today to schedule an appointment to discuss your questions about tooth-colored restorations. You can also learn more by reading the Dear Doctor magazine article “The Natural Beauty of Tooth-Colored Fillings.”
