Dental fillings are a common and essential solution for treating cavities, helping to restore the health and function of damaged teeth. If you’ve recently been told you need a filling, you might find yourself wondering which option to choose: amalgam (silver) fillings or composite (white) fillings. Both have their pros and cons, but the right choice depends on your unique dental needs, budget, and personal preferences. Let’s explore the key differences to help you make an informed decision.

What Are Amalgam Fillings?

Amalgam fillings are made from a mix of metals, including silver, tin, copper, and mercury. Yes, mercury—don’t panic! This component binds the metals together and makes the filling strong and durable. In fact, amalgam fillings have been used for over 150 years, making them one of the oldest and most tested dental materials available.

Key features of amalgam fillings:

• Highly durable, lasting 10–15 years or more.
• Particularly effective for molars, where chewing pressure is greatest.
• Less expensive than composite fillings.

What Are White Fillings?

White fillings, also known as composite fillings, are made from a blend of plastic and fine glass particles. They’re specifically designed to blend seamlessly with your natural teeth, making them an increasingly popular choice for modern dentistry. Composite fillings are often used for both cosmetic and restorative purposes, as they’re aesthetically pleasing and functional.

Key features of white fillings:

• Match the colour of your natural teeth, making them virtually invisible.
• Ideal for visible teeth and smaller cavities.
• Require more skill and time to place, which may increase their cost.

Comparing Amalgam and White Fillings

Here’s a closer look at how these two types of fillings stack up:

1. Durability

• Amalgam: Known for its incredible strength and ability to withstand heavy chewing forces. Perfect for back teeth where durability matters most.
• White Fillings: While less durable than amalgam, advancements in materials have made them more resilient, lasting 5–10 years with proper care.

2. Appearance

• Amalgam: Its metallic color is visible, which makes it less appealing for front teeth or anyone concerned about aesthetics.
• White Fillings: These blend beautifully with natural teeth, making them a go-to choice for patients seeking a natural look.

3. Cost

• Amalgam: Generally more affordable and widely covered by insurance.
• White Fillings: Slightly more expensive due to material costs and the longer time required for placement.

4. Safety

• Amalgam: Concerns about mercury have been raised, but according to the American Dental Association (ADA), amalgam fillings are safe for most people. The mercury is bound within the alloy and not harmful in its hardened form.
• White Fillings: Free of mercury, but they may release trace chemicals during the curing process. These are considered safe by dental regulatory bodies.

5. Procedure Time

• Amalgam: Quicker and less technique-sensitive to place.
• White Fillings: Placement is more complex, requiring layering and curing with a special light.

Advantages and Disadvantages of Amalgam and White Fillings

Amalgam Fillings

Pros:

• Highly durable and long-lasting.
• Cost-effective and quick to place.
  Cons:
• Metallic appearance.
• Can cause slight tooth discoloration over time.
• Concerns about mercury content (though deemed safe by experts).

White Fillings

Pros:

• Aesthetic appeal, blending naturally with your teeth.
• Versatility for front and back teeth.
  Cons:
• Less durable than amalgam for high-pressure areas.
• Higher cost and more time-consuming placement.

What Do Experts Say?

The ADA and World Health Organization support the safety and effectiveness of both amalgam and composite fillings when used appropriately. However, trends in modern dentistry lean toward white fillings due to their natural appearance and advancements in durability.

According also to Colgate, “Amalgam fillings are durable and economical, but white fillings are the better choice for a natural look.”

Which Filling Should You Choose?

Choosing the right filling depends on several factors:

• Location of the cavity: Amalgam is better for molars; composite works well for visible teeth.
• Aesthetic preferences: If you care about a natural look, white fillings are the way to go.
• Budget and insurance: Amalgam is more affordable, but many insurance plans now cover composites.
• Your dentist’s advice: They’ll consider your oral health, cavity size, and personal preferences to recommend the best option.
