When you think of a filling, you might picture a silver spot on a molar—the kind many people grew up with. Those silver-colored fillings are made of a material called amalgam. They’ve been around for over a century, and they’re still used in some dental offices today.
But times have changed, and so have the materials we use to restore teeth. At Radomile Family Dental in Drexel Hill, NJ, we believe composite fillings are often a better choice for most patients. These tooth-colored fillings offer benefits that go beyond appearance. They’re strong, conservative, and blend in so well that no one will even know you had dental work done.
Let’s take a closer look at how composite fillings compare to traditional amalgam and why more patients are choosing the modern option.
What Are Composite Fillings?
Composite fillings are made from a mixture of resin and fine glass particles. The material is carefully color-matched to your natural tooth and bonded directly to the damaged area.
They’re often used to treat:
- Cavities
- Small chips or cracks
- Worn teeth from grinding
- Replacing old or damaged amalgam fillings
The resin is soft when applied, shaped in layers, and then hardened using a special curing light. Once it’s set, the filling looks and feels like your natural tooth.
What Is Dental Amalgam?
Dental amalgam is a metal alloy made from a combination of mercury, silver, tin, and copper. It has been used in dentistry for more than 150 years. It’s strong, durable, and can withstand heavy chewing forces, which is why it was traditionally used for back teeth.
Amalgam fillings appear silver or gray, and over time, they can darken. While they are still approved by dental organizations, many people prefer not to use them anymore, especially when more natural-looking alternatives are available.
Appearance Matters: The Aesthetic Advantage of Composite Fillings
One of the most obvious benefits of composite fillings is that they look like real teeth. When placed properly, they’re nearly impossible to spot. This makes them an ideal choice for teeth that show when you smile or speak.
Whether the filling is on the front or back of your mouth, you don’t have to worry about flashing a metallic grin every time you laugh.
Amalgam, on the other hand, is visibly silver from the start and can get darker over time. Even small fillings can be noticeable, especially in well-lit rooms or photos.
At Radomile Family Dental, we take the time to match the composite shade to your unique tooth color so it blends in seamlessly.
Less Invasive, More Tooth Preservation
Composite fillings also allow us to be more conservative with your natural tooth. Because the resin bonds directly to the enamel, we can remove less healthy structures compared to what’s required for amalgam.
Here’s why that matters:
- Less drilling means stronger teeth in the long run
- The tooth is less likely to crack over time
- Future restorations are easier and less complicated
Amalgam fillings require us to shape the tooth in a specific way so the material can hold its place. That often means removing more healthy tissue than necessary. Composite materials, by contrast, work with the natural structure rather than against it.
Better Bonding and Sealing
Composite resin chemically bonds to the tooth. That creates a tight seal between the filling and the enamel, which helps prevent bacteria from sneaking in and causing further decay.
This strong bond is one of the biggest advantages of composites. It helps reinforce the tooth and reduces the risk of future problems.
Amalgam does not bond with the tooth. Instead, it relies on mechanical retention, basically the shape of the cavity, to stay in place. Over time, that can lead to tiny gaps between the filling and the tooth, which can trap bacteria and lead to secondary decay.
Less Temperature Sensitivity
One issue with metal fillings is how they react to temperature changes. Metal expands and contracts more than tooth enamel, so drinking hot coffee or eating ice cream can cause the filling to shift slightly. Over time, those tiny movements can cause cracks in the tooth or the filling itself.
Composite fillings respond more like natural tooth structure, which makes them more stable and less prone to temperature-related problems.
If you’ve ever had a filling that felt extra sensitive in cold weather or after drinking something hot, there’s a good chance it was metal. Composite tends to be more comfortable in daily life.
No Mercury Content
Another concern some patients have about amalgam is its mercury content. While the mercury in dental fillings is considered safe by the American Dental Association and FDA, some people prefer to avoid it altogether.
Composite fillings are mercury-free and contain no metal. That makes them a preferred option for patients who are sensitive to metals or simply want a more natural alternative.
At Radomile Family Dental, we respect your preferences. If you’re looking for a metal-free filling, composite is the clear choice.
Durability You Can Count On
While amalgam has a reputation for durability, composite materials have come a long way in recent years. Today’s resin blends are stronger than ever and can handle the demands of chewing, especially in small to medium-sized fillings.
With good oral hygiene and regular dental checkups, a composite filling can last 7 to 10 years or longer.
They are also easier to repair than amalgam. If a composite filling chips or wears down slightly, we can usually add more material without having to remove the whole thing.
When Might Amalgam Still Be Used?
While we prefer composite fillings in most cases, there are rare situations where amalgam may still be appropriate. For example:
- Extremely large fillings in back teeth under heavy pressure
- Situations where a dry working area is hard to maintain
- Temporary restorations or repairs in patients with limited access to care
That said, these situations are the exception, not the rule. In nearly every other case, composite provides the better experience, for both aesthetics and function.
Replacing Old Amalgam Fillings
If you already have silver fillings, there’s no need to panic. Many are still functional and don’t need to be replaced unless they are cracked, leaking, or showing signs of wear.
However, some patients choose to replace old amalgam fillings with composite for cosmetic reasons or peace of mind. If you are thinking about making a change, we can evaluate your existing fillings and let you know what’s possible.
In most cases, we can remove the metal filling and restore the tooth with composite in a single visit.
Choosing the Right Filling for You
At Radomile Family Dental, we believe in personalized care. That means we don’t push one-size-fits-all treatments. Instead, we look at your teeth, your goals, and your preferences to help you decide what makes the most sense for your smile.
Composite fillings offer several advantages that make them a great fit for most people:
- They look natural
- They preserve more of your tooth
- They bond tightly and protect against further decay
- They are metal-free and mercury-free
- They are comfortable and durable
Whether you need a brand-new filling or want to replace an older one, our team is here to walk you through the process and make sure you feel confident every step of the way.

Frequently Asked Questions
Are composite fillings better than silver fillings?
For many people, yes. Composite fillings blend in with your natural tooth color, bond more securely, and allow us to preserve more of your tooth. They’re a great option for small to medium cavities, especially in visible areas.
Do composite fillings last as long as amalgam?
Composite fillings typically last 7 to 10 years, depending on the size of the filling and your oral habits. While amalgam has a longer track record, today’s composite materials are highly durable and hold up well under daily use.
Is it safe to replace old silver fillings with composite?
Yes, it’s safe when done correctly. We take extra care when removing old amalgam fillings to minimize any exposure to metal particles. Once removed, we restore the area with a tooth-colored composite that matches your smile.
Do composite fillings cost more than amalgam?
Composite fillings can be slightly more expensive, especially for larger restorations. However, many insurance plans cover both types. We’re happy to review your coverage and help you understand your options before any treatment.
Can you get composite fillings for back teeth?
Absolutely. Composite fillings work well for molars and premolars. They can handle everyday chewing pressure, and they look more natural than metal fillings when you open your mouth or smile.
