Cavity filling material—ranging from traditional amalgam to tooth-colored composites and even natural alternatives like glass ionomer—is essentially a durable substance designed to seal holes in your teeth, restore function, and blend seamlessly with your smile, all while stopping bacteria in their tracks. Whether you’re dealing with your first filling or just curious about dental repairs, this beginner-friendly guide breaks it down simply: what each type is, pros and cons, and how to choose the right one for your needs. Let’s fill in the gaps and get you informed for that next check-up!
The Main Types of Filling Materials
Dentists pick from several materials based on cavity size, location, and your preferences. Amalgam, a mix of metals like silver and mercury, has been around forever for back teeth. Composites are resin-based and match your tooth color. Porcelain or ceramic offers a premium feel, gold is old-school tough, and glass ionomer releases fluoride for extra protection.
Amalgam Fillings: The Classic Choice
These silver fillings are super strong and cheap, ideal for molars under heavy chewing.
Pros: Last 10-15 years, affordable, and quick to place.
Cons: Visible metallic look, contains mercury (safe per studies but some worry), and can expand/contract with temps.Great if aesthetics aren’t key.
Composite Fillings: For a Natural Vibe
Made from plastic resins and glass particles, these blend right in.
Pros: Tooth-colored for front teeth, bond directly for support, less tooth removal needed.
Cons: Wear out in 5-10 years, prone to staining from coffee or wine, and cost more upfront. Perfect for visible spots.
Porcelain or Ceramic: The Fancy Option
Crafted from baked clay-like material, these mimic enamel shine.
Pros: Stain-resistant, natural appearance, durable for larger fills.
Cons: Brittle if not handled right, pricier, and might need multiple visits. Good for folks wanting long-term beauty.
Gold Fillings: Timeless Strength
Alloy of gold and other metals, these are custom-lab made.
Pros: Extremely durable (20+ years), biocompatible, no corrosion.
Cons: Expensive, metallic shine stands out, longer process. Best for back teeth in high-wear mouths.
Glass Ionomer: The Fluoride Booster
A mix of glass and acrylic that releases fluoride over time.
Pros: Bonds chemically, fights decay, gentle on kids’ teeth.
Cons: Least durable (5 years max), wears quickly in chew-heavy areas. Handy for small cavities or temporary fixes.
