Cracked or worn silver amalgam fillings can be replaced with ceramic or composite ones. These newer options are more durable, mercury-free, and have a more natural appearance, making them a safer and better-looking option for many patients.
Replacing silver amalgam fillings with composite fillings is an increasingly common dental procedure aimed at improving both the appearance and structural integrity of teeth. Amalgam fillings, made from a mix of metals, can cause teeth to look dark and are more visible when speaking or smiling. Composite fillings, in contrast, are crafted from a tooth-colored resin that can be closely matched to the natural shade of your teeth, providing a seamless, natural look.
At Norman Smile Center, led by Drs. Kristen Campbell and Donna Sparks, we’re proud to offer the latest in restorative and cosmetic treatments, including composite fillings. For more than 30 years, we’ve been providing exceptional dental care to patients in and around the Norman area, and we strive to stay at the forefront of dental treatments, techniques, and procedures to help ensure your smile is as healthy and beautiful as possible. Your smile says a lot about you, and by replacing your silver amalgam fillings, you can let it shine without distraction.
A Short History of Silver Amalgam Fillings
Silver amalgam fillings have been used in dental care for over 150 years. They are made from a combination of metals, which include mercury, silver, tin, and copper. Durable and strong, they are less likely to break than some other materials. Dentists often recommend silver fillings for their ability to withstand the pressures of chewing — especially in molars where they are subjected to the most pressure.
However, despite their long-standing use and reputation, silver fillings have some downsides. One of the main concerns is the mercury content. While the FDA considers dental amalgam fillings safe for most patients, it acknowledges that some people — such as those with preexisting health conditions or who are sensitive to mercury — may want to avoid them. The ADA has reaffirmed its position that amalgam fillings remain safe and effective but recognizes the environmental concerns of using mercury, especially when not properly disposed of.
Composite Fillings as a Substitute for Silver Amalgam
Composite fillings, or tooth-colored restorations, can be used as a substitute or replacement for silver amalgam fillings. They are designed to closely match the natural color and texture of teeth, offering a more subtle alternative to amalgam fillings. These restorations are commonly used to fill cavities and are also effective in repairing minor fractures or chips.
Unlike amalgam, composite materials require minimal removal of tooth structure, preserving more of the natural tooth. Their biocompatibility and ability to bond directly to the tooth surface also make composites a practical option for cosmetic applications, particularly for improving the appearance of visible teeth.
Ceramic and composite fillings have become popular choices for both new fillings and replacements. There are several reasons they could be a good option for you, including:
- A more natural appearance. Unlike silver fillings, ceramic and composite fillings are made to blend in with the natural color of your teeth. This makes them a great choice for anyone who wants to avoid the silver look of amalgam.
- Durability. Modern ceramic and composite materials have come a long way in terms of strength and longevity. If you care for them properly, they can last for 10 to 15 years or longer.
- Safety. One of the main reasons patients choose ceramic or composite fillings is because they contain no mercury. For those who are worried about the potential health risks associated with mercury amalgam, using ceramic or composite materials provides peace of mind.
- Improved bonding. Silver amalgam fillings are placed into a cavity and packed in and over time they can loosen or fall out. However, composite and ceramic fillings bond directly to the tooth. This creates a tight seal that helps prevent further decay and strengthens the tooth.
3 Reasons to Replace Silver Amalgam Fillings
Silver amalgam fillings are durable and functional. However, there are a few reasons why you might want to replace them with composite fillings.
- Health concerns. Mercury is a key component of dental amalgam fillings, and for some patients, exposure to mercury raises concerns. Studies have shown that amalgam fillings release a minimal amount of mercury, and using them is safe and doesn’t create a health risk. However, some people who have conditions like allergies or kidney issues may want to replace them with more modern ceramic or composite materials that do not contain mercury.
- Aesthetics. Silver fillings are highly visible in your mouth — even in your back teeth when you laugh or smile. For people who want a more natural appearance, the silver coloring is a concern. Ceramic and composite fillings blend in seamlessly with the rest of your teeth and help keep your smile more natural-looking.
- Wear and tear. Dental amalgam fillings break down over time and separate from the enamel, which leads to cracking, wearing down, or becoming loose in your tooth. This can also lead to additional tooth decay or even cracks in your teeth. If your fillings have begun to show signs of wear, your dentist may recommend replacing them with ceramic or composite materials.
There are many reasons why people choose to replace their silver fillings. Switching to ceramic or composite fillings can have both cosmetic and practical benefits — from repairing aging fillings or potential health risks from mercury to improving the appearance of your smile.
The decision to replace your fillings is personal, and you’ll need to consider your dental health, budget, and specific needs. Consulting with your dentist is the best way to determine if it’s worth it for you to replace your fillings.
Types of Silver Amalgam Replacements: Ceramic vs. Composite
When deciding to replace your silver fillings, you’ll have two main choices: ceramic or composite fillings. The right option for you depends on the size and location of the cavity and your budget. Composite fillings are a good choice for smaller, less visible areas. Ceramic is preferred for larger cavities and areas where strength is critical. Your dentist will discuss the pros and cons of each with you and can help you decide which material will best meet your needs, but here are the primary differences:
Composite Fillings
Composite fillings are made from a material that is a mix of resin and powdered quartz or silica particles. They are ideal for smaller cavities and areas of the mouth that don’t endure heavy pressures from chewing. One of the main advantages of composite is that it’s a more affordable option and quicker to place. However, the composite material may not be as durable as ceramic, especially when it is used in molars or other areas that receive a lot of biting pressure.
Ceramic Fillings
These are made from porcelain or other strong ceramic materials. Dentists often use ceramic materials for larger cavities or in molars because they are especially strong and long-lasting. Ceramic is also highly resistant to staining, which is great for coffee or tea drinkers. Ceramic fillings can be more expensive and may take longer to fit (because they need to be custom shaped) but they are an excellent choice because of their strength and appearance.
Replacing Your Silver Amalgam Fillings: What to Expect
If you’re considering replacing your silver fillings, you may be curious about what the process involves. Here’s an overview of the general steps to replacing silver amalgam fillings:
1. Consultation with Your Dentist
The first step is to meet with your dentist. They will check your fillings and look for signs that they need to be replaced, such as wear, decay, or damage to them. They may also take X-rays to see if the tooth beneath the filling is in good shape or if it is showing signs of cavities. They’ll discuss all aspects of replacing the fillings and help you decide if it’s the right thing for you.
2. Removing the Silver Fillings
If you decide to move forward, the next step is taking out the old silver amalgam fillings. Your dentist must work carefully to prevent exposing you to mercury. They will use special techniques, including using a high-volume suction to prevent you from inhaling or swallowing the small mercury particles. Dentists take extra care to make sure you are safe and comfortable.
3. Filling the Tooth
Once your old silver filling has been removed, your tooth will be cleaned and prepared for the new filling. If your dentist finds any signs of decay, they will remove it before placing the new filling. The material they use — composite or ceramic — will depend on the size and location of the cavity.
4. Shaping and Polishing
Once the new filling is in place, your dentist will need to shape it to fit your bite and make sure it matches the rest of your teeth. This is an important step to make sure the new filling doesn’t create changes to your bite pattern, which can cause your teeth or jaw to hurt. The last step is to polish the filling so that it has a smooth finish and looks natural.
5. Post-Procedure Care
For most patients, there is little to no discomfort afterward, but you may notice some sensitivity to cold foods for a few days. Be sure to follow your dentist’s instructions — brushing and flossing regularly and avoiding hard or sticky foods while your new filling settles in.
