For decades, silver (amalgam) fillings were the most common way to treat cavities. They’re strong and affordable—but dentistry has evolved. Today, white (composite) fillings are becoming the preferred choice, and here’s why.
The Downside of Silver Fillings
Silver fillings are made of a mixture of metals, including about 50% mercury, along with silver, tin, and copper. While durable, they come with drawbacks:
• ❌ Noticeable dark color that shows when you talk or smile.
• ❌ Require removing healthier tooth structure to stay in place.
• ❌ Metals expand and contract with temperature changes, which can cause small cracks in the tooth over time.
• ❌ do not bond to the tooth—they simply “sit” inside, relying on mechanical retention.

Why White Fillings Are the Better Option

Composite fillings are made from a tooth-colored resin that blends perfectly with your natural teeth. But their benefits go far beyond appearance:
• ✅ Natural look – completely invisible when you smile.
• ✅ Tooth preservation – less drilling, so more of your natural tooth is kept.
• ✅ bonding technology – the filling adheres directly to the tooth, sealing out bacteria and strengthening the tooth.
• ✅ Mercury-free – no metals, making them safer and more biocompatible.
• ✅ Versatile – can be used on both front and back teeth with excellent results.

The Takeaway
Both options can restore a tooth, but composite fillings provide a modern, safe, and natural-looking solution. Patients today choose them not only for aesthetics, but also for the health and strength of their smile.
