Amalgam Dental Restorations: A Durable Solution Against Cavities

What is dental amalgam?

Dental amalgam is a filling material used for over a century in dentistry to restore decayed teeth. It is made from a mixture of metals (silver, tin, copper) and mercury, forming a paste that hardens once placed in the tooth.

Why use amalgam?

Despite advances in modern dental materials like composites, amalgam remains widely used due to its strength. It is especially recommended for:

• Molars (which endure strong chewing forces)

• Less visible areas

• Patients with limited budgets

• Large restorations

Advantages of amalgam

✅ High wear resistance
✅ Long lifespan (15 to 20 years)
✅ Less expensive than aesthetic alternatives
✅ Quick placement in a single visit

Considerations

⚠️ Metallic color, less aesthetic
⚠️ Sometimes requires removal of healthy tooth tissue
⚠️ Mercury controversy (though its use is authorized and safe)
⚠️ Not recommended for pregnant women or children under 15 in some countries

Is it legal and safe?

Yes. In Tunisia and many countries, amalgam use is still authorized under regulated conditions. Mercury levels are very low and strictly controlled. Studies have confirmed its safety when used properly.

Alternatives to amalgam

For aesthetic or medical reasons, alternatives include:

• Dental composites (white fillings)

• Ceramic or composite resin inlays/onlays

These are more discreet but may be less durable in the back teeth.
