When it comes to dental fillings, many patients wonder about the best material for restoring their teeth. Traditionally, amalgam fillings (silver fillings) have been widely used due to their durability. However, with advancements in dental materials, composite fillings (tooth-colored fillings) have become the preferred choice.
If you still have old amalgam fillings, you might be wondering whether to replace them with composite fillings. In this blog, I will explain the differences, benefits, and why replacing amalgam fillings with composite is a smart choice for your dental health.
What Are Amalgam and Composite Fillings?
Amalgam Fillings
Amalgam fillings are made from a mixture of silver, tin, copper, and mercury. While they are strong and long-lasting, they come with some downsides, particularly their metallic appearance and mercury content.
Composite Fillings
Composite fillings are made from a resin-based material mixed with glass particles. They are tooth-colored, blend naturally with your teeth, and provide a durable, aesthetic, and safe alternative to amalgam.
Key Differences Between Amalgam and Composite Fillings
| Feature | Amalgam Fillings | Composite Fillings |
| Material | Silver, mercury, copper, tin | Resin and glass particles |
| Appearance | Metallic, noticeable | Tooth-colored, blends naturally |
| Durability | Lasts 10-15 years | Lasts 7-10 years, with proper care |
| Safety | Contains mercury | Mercury-free |
| Bonding to Tooth | Does not bond directly to tooth | Bonds directly, strengthening the tooth |
| Tooth Removal | Requires more removal of tooth structure | Preserves more of the natural tooth |
| Temperature Sensitivity | Expands/contracts with temperature changes, increasing risk of cracks | Less sensitive to temperature changes |
| Toxicity Concern | Mercury release can be a concern | Safe and biocompatible |
Why You Should Replace Your Amalgam Fillings with Composite Fillings
1. Aesthetics – A Natural Look
One of the biggest reasons to replace your silver fillings is for a more natural and attractive smile. Composite fillings match your natural tooth color, making them virtually invisible.
2. No Mercury Exposure
Amalgam fillings contain about 50% mercury, which can release small amounts of vapor when chewing or grinding. While the FDA considers it safe for most adults, many patients prefer to eliminate any potential risks associated with mercury exposure.
3. Stronger Tooth Structure
Composite fillings bond directly to your tooth, strengthening it and reducing the risk of fractures. Amalgam, on the other hand, can cause cracks over time due to its expansion and contraction with temperature changes.
4. Less Tooth Removal
To place an amalgam filling, more of the natural tooth structure needs to be drilled away. With composite fillings, we remove only the decayed portion, preserving more of your healthy tooth.
5. Reduced Sensitivity
Metal fillings react to temperature changes, causing tooth sensitivity when eating or drinking something hot or cold. Composite fillings are less reactive, leading to greater comfort.
6. Environmentally Friendly
Amalgam contains mercury, which is harmful to the environment when disposed of. Composite fillings are eco-friendly and safe for disposal.
FAQs: Replacing Amalgam Fillings with Composite Fillings
Q: Is it safe to remove old amalgam fillings?
Yes! At VCare Family Dental, we use safe removal techniques to minimize mercury exposure. We follow strict protocols, such as using a rubber dam, high-speed suction, and proper ventilation.
Q: How long does the replacement procedure take?
Replacing an amalgam filling with composite takes about 30-60 minutes per tooth, depending on the size and location of the filling.
Q: Will it hurt to replace my fillings?
No. We use local anesthesia to ensure you are completely comfortable during the procedure. Most patients experience minimal discomfort afterward.
Q: How long do composite fillings last?
With proper care, composite fillings can last 7-10 years or more. Maintaining good oral hygiene and regular check-ups can extend their lifespan.
Q: Is the cost of composite fillings worth it?
Yes! While composite fillings may be slightly more expensive than amalgam, they offer superior aesthetics, safety, and long-term benefits for your dental health.
Q: Can I replace all my amalgam fillings at once?
It depends on the number of fillings you have and your oral health. We often recommend replacing them gradually for patient comfort and cost management.
