Walk into most dental offices, and you might still see silver fillings. Those dark, metal spots are so common that many patients assume they are the only option. But at 615 Smile Design, we made a different choice. We only use metal-free fillings and tooth-colored restorations. And once you understand why, you’ll probably want to make the same choice for your smile.

What Are Metal-Free Restorations?
Metal-free restorations are fillings, crowns, and other dental repairs made from advanced ceramic or composite resin materials. They look natural. They blend in with your teeth. And they do not contain any metal whatsoever.
All of our metal-free restorations are fabricated right here in the United States using innovative, high-quality materials. That means better quality control and stronger, longer-lasting results for our patients in Nashville and the surrounding areas.
The Problem with Silver Fillings (Amalgam)
Traditional silver fillings, also called amalgam, have been around for over a century. They work, but they come with real drawbacks:
- They contain mercury. Most amalgam fillings are about 50 percent mercury, along with silver, tin, and copper. Many patients prefer to avoid mercury entirely.
- They expand and fracture teeth. Metal expands and contracts with temperature changes. Over time, that movement can damage the natural tooth around the filling.
- They leave dark stains. That gray or black color eventually seeps into the tooth structure, leaving a permanent shadow.
- They require removing healthy tooth. To hold a silver filling in place, the dentist must remove more of the natural tooth. That weakens the tooth over time.
Why We Prefer Metal-Free Restorations
At 615 Smile Design, we believe patients deserve better. Here’s what makes metal-free restorations the smarter choice:
- Natural Appearance: Tooth-colored restorations blend in perfectly. No one will ever know you had a filling or a crown. Dr. Sivaneri takes special care to match the shade, shape, and translucency of your natural teeth.
- Strong and Long-Lasting: Some patients worry that metal-free means weak. That’s not true anymore. Modern ceramic and composite materials are incredibly strong. They bond directly to the tooth, which actually reinforces the natural structure instead of weakening it.
- No Metal Sensitivity: Some patients have allergic reactions or sensitivity to metal. Others simply don’t want metal in their mouths. Metal-free restorations remove that concern completely.
- Preserves More Natural Tooth: Because metal-free materials bond directly to the tooth, we don’t need to remove as much healthy enamel. That means your tooth stays stronger for longer.
Metal-Free Fillings, Crowns, and More
We use metal-free restorations for nearly every procedure:
- Fillings for cavities
- Crowns to cover damaged teeth
- Veneers for smile makeovers
- Inlays and onlays for larger cavities
Dr. Sivaneri has advanced training in cosmetic and restorative dentistry through Spear Education. That means he knows how to place metal-free restorations that look beautiful and function perfectly.
What About Cost?
Metal-free restorations are often comparable in price to metal ones, especially when you consider the long-term benefits. A silver filling might need replacement sooner. It might damage the tooth or leave an ugly stain. Over time, metal-free restorations can actually save patients money by avoiding those problems. Our team works with each patient to make quality dentistry affordable.
Your Smile Deserves Better
You only get one set of natural teeth. Why fill them with metal when a better option exists?
At 615 Smile Design, we choose metal-free restorations because we care about your health, your appearance, and your long-term confidence. From routine fillings to complete smile makeovers, every restoration we place is strong, beautiful, and completely metal-free.
