Tooth-Colored Fillings vs Metal Fillings

Understanding Dental Fillings: Tooth-Colored vs Metal

Dental fillings restore teeth damaged by cavities. This guide compares composite (tooth-colored) and amalgam (metal) fillings to help you make an informed, confident decision for your oral health.

Key Facts About Tooth-Colored and Metal Fillings

• Composite: Resin + glass/ceramic; natural-looking, mercury-free, bonds to tooth
• Amalgam: Mercury + metals; strong, cost-effective, lasts longer, visible
• Durability: Composite lasts 5–10 years; metal 10–15+ years
• Cost: Composite ($150–$250); Metal ($50–$150)
• Suitability: Composite ideal for visible teeth; metal preferred for molars

1. Tooth-Colored Fillings

• Material: Composite resin blended with glass particles
• Aesthetics: Shade-matched to your natural teeth
• Bonding: Adheres directly to tooth, conserving healthy enamel
• Durability: 5–10 years with proper care
• Health & Safety: Mercury-free, low allergy risk, thermally stable
• Uses: Best for small–medium cavities, front teeth, cosmetic bonding

2. Metal Fillings

• Material: 50% mercury + silver, tin, copper
• Strength: Excellent for heavy chewing forces and large cavities
• Longevity: 10–15 years, some last 20+ with care
• Cost: More affordable, faster placement
• Safety: Considered safe by FDA/ADA, though mercury concerns exist
• Common Use: Ideal for molars and out-of-sight restorations

Key Considerations and Comparisons

• Appearance: Composite wins for aesthetics
• Durability: Metal offers longer lifespan in high-stress areas
• Cost: Metal is less expensive upfront
• Safety: Composite preferred for those concerned about mercury
