# Why We Don't Use Silver Fillings (And What We Use Instead)
If you have ever had a cavity filled, chances are you are familiar with silver (amalgam) fillings. They have been used in dentistry for over 150 years. But at East Lake Dental, we made the decision to be a mercury-free practice. Here is why, and what we offer instead.

What Are Silver Fillings Made Of?
Despite the name, "silver" fillings are not pure silver. They are a mixture of metals called dental amalgam, which typically contains about 50% mercury along with silver, tin, and copper. The mercury binds these metals together into a durable filling material.
While the American Dental Association considers amalgam safe for most adults, the FDA has recommended that certain groups consider alternatives. These include pregnant women, nursing mothers, children under six, and people with mercury sensitivities or kidney conditions.

Why We Chose to Go Mercury-Free
Our decision to stop using amalgam comes down to three things:
Better Materials Are Available
Modern composite resins are strong, long-lasting, and continue to improve every year. When we have an option that works well and does not contain mercury, we see no reason to use the older material.
Composites Preserve More Tooth Structure
Amalgam fillings require the dentist to remove more healthy tooth material to create a shape that holds the filling in place. Composite fillings bond directly to the tooth, so we only need to remove the decayed portion. That means more of your natural tooth stays intact.
They Look Natural
Composites are matched to the color of your teeth. Once placed, they are virtually invisible. No more dark spots when you smile or laugh.

Composite vs. Amalgam: How They Compare
| Feature | Composite (Tooth-Colored) | Amalgam (Silver) |
|---|---|---|
| Appearance | Matches your tooth color | Dark silver/gray |
| Mercury content | None | About 50% |
| Tooth removal needed | Less (bonds directly) | More (needs mechanical retention) |
| Strength | Strong, improves over time | Very strong |
| Sensitivity | Minimal | Can expand/contract with temperature |
| Lifespan | 7-15 years with proper care | 10-15 years |

What to Expect When Getting a Composite Filling
The process is straightforward and usually completed in a single visit:
- We numb the area so you are comfortable
- The decayed portion of the tooth is removed
- The tooth is cleaned and prepared
- Composite resin is applied in layers, each one hardened with a curing light
- The filling is shaped and polished to match your natural bite
Most patients are surprised at how quickly it is done. You can eat and drink normally within a few hours.

Should You Replace Your Old Silver Fillings?
This is one of the most common questions we hear. Our recommendation: if your amalgam fillings are intact and not causing problems, there is no urgent need to replace them. Removing a functional filling means removing additional tooth structure.
However, we do recommend replacement when:
- The filling is cracked, leaking, or showing signs of decay underneath
- You are experiencing sensitivity around an old filling
- You want to eliminate mercury from your mouth for personal reasons
We will always give you an honest assessment and let you make the decision that is right for you.
