The Pros and Cons of Dental Amalgam Fillings – What Patients in Everett and Seattle Should Know
Have you ever been told you have a cavity and wondered, “What’s the best kind of filling for me?” You’re not alone. For many patients, that question leads to comparing options like tooth-colored composites, porcelain, or the often-overlooked silver-colored dental amalgam fillings.
If you grew up in Everett or Seattle, there’s a good chance you already have one or two of these in your mouth. But with newer materials now available, you might be wondering: are amalgam fillings still worth it?
Here’s the truth: amalgam fillings have been around for over 150 years, and there are some good reasons why. But they’re not for everyone.
In this guide, we’re breaking down the pros and cons of dental amalgam fillings so you can make the most informed decision possible—especially if you’re debating cost, durability, or long-term aesthetics.
Let’s take a look at everything you need to know before sitting in the dentist’s chair.
What Are Dental Amalgam Fillings?
Dental amalgam is a metal-based filling material created by combining liquid mercury with a powdered alloy composed of silver, tin, and copper. When these ingredients are mixed, they form a putty-like substance that your dentist places into a cavity. As it hardens, it forms a durable seal that protects the tooth from further decay.
Amalgam is especially effective in molars and premolars—teeth that handle the heavy lifting of chewing. That’s why it has remained a common solution for back teeth, especially in children and patients looking for a cost-effective option.
The Pros of Dental Amalgam Fillings
While newer materials like composites and porcelain are gaining popularity, silver amalgam fillings still offer several benefits:
1. Proven Durability
Amalgam fillings are tough. They can withstand significant chewing forces, which makes them ideal for molars. Most amalgam fillings last 10–15 years or longer, outperforming some modern alternatives in high-pressure areas.
2. Budget-Friendly Treatment
Cost is often a deciding factor. Amalgam is one of the most affordable dental filling materials available. For patients in Everett or Seattle without dental insurance, this can make a big difference when choosing treatment options.
3. Faster Procedure
Because amalgam hardens quickly and doesn’t require a completely dry field, dentists can place these fillings faster and more easily than resin composites, especially in difficult-to-reach areas.
4. Resistance to Future Cavities
Some studies show that amalgam fillings may help make the edges of treated teeth more resistant to recurring cavities, offering a level of protection against future decay.
5. Long-Term Chewing Confidence
Patients with amalgam fillings report being able to chew normally and confidently, even with hard or sticky foods, without fear of the filling breaking.
The Cons of Dental Amalgam Fillings
Despite its strengths, amalgam comes with several drawbacks that may make you consider other restorative options.
1. Cosmetic Concerns
Amalgam fillings are noticeably silver and can darken over time, making them more visible—especially when you laugh or yawn. This aesthetic issue is why many patients now prefer tooth-colored composite fillings, particularly for front-facing teeth.
2. Tooth Sensitivity
Some patients experience increased tooth sensitivity after receiving amalgam fillings. The metal can expand and contract with temperature changes (like hot coffee or ice water), which may lead to microfractures or discomfort.
3. Potential Tooth Weakening
To place an amalgam filling, your dentist may need to remove more of the natural tooth structure than with a composite filling. This can potentially weaken the overall tooth and increase the chance of cracking over time.
4. Staining Around the Filling
Amalgam may stain the surrounding tooth structure, resulting in a grayish or dark appearance around the filled area. In many cases, these stains cannot be removed without also removing the filling. This is especially relevant if you’re considering teeth whitening treatments down the road, as amalgam may limit whitening effectiveness around filled teeth.
5. Mercury Content
Perhaps the most controversial topic is that amalgam fillings contain mercury—a substance that, in high amounts, can be toxic. While the FDA and ADA have stated that dental amalgam is safe for most people, this remains a concern for some patients. More on this below.
Understanding Mercury Concerns in Amalgam Fillings
Yes, dental amalgam contains mercury—about 50% by weight. But not all mercury is created equal. The type used in fillings is bound within a stable alloy that significantly limits its release into the body. Most studies show that the amount of mercury released during chewing or brushing is well below harmful levels.
Still, some groups—including pregnant women, children under six, and individuals with kidney problems—are advised to avoid amalgam fillings where possible. For patients in the Everett or Seattle area who are concerned, our dental team at Icon Dental Center offers alternative restorative options, such as composite, ceramic, or resin-based fillings.
