White Fillings vs Silver Fillings: What’s the Difference?

Introduction

If you need a dental filling, you may be wondering whether white (composite) fillings or silver (amalgam) fillings are the better option. While both restore teeth affected by decay, they differ in appearance, material, and overall benefits. Learn more about cavity fillings in Toronto and which option may be right for you. At Teeth & Beauty Toronto, we help patients choose the right option based on their oral health, aesthetic goals, and long-term needs.

1. What Are Silver (Amalgam) Fillings?

Silver fillings, also known as amalgam fillings, have been used in dentistry for decades. They are made from a mixture of metals, including silver, tin, copper, and mercury.

Advantages:

• Strong and durable

• Often used for back teeth

• Resistant to heavy chewing forces

However, silver fillings are highly visible and may expand or contract over time due to temperature changes.

2. What Are White (Composite) Fillings?

White fillings are made from a tooth-colored composite resin that blends naturally with your enamel. They are bonded directly to the tooth structure, allowing for a more conservative and aesthetic restoration.

Advantages:

• Natural-looking

• Bonds to the tooth for added support

• Preserves more natural tooth structure

• Popular for both front and back teeth

Composite fillings are now the preferred option for many patients seeking both durability and aesthetics.

3. Which Option Is More Durable?

Both materials are durable when properly placed and maintained. Silver fillings have historically lasted longer in high-pressure areas, but modern composite materials are highly advanced and perform extremely well.

Longevity depends on:

• Size of the filling

• Location of the tooth

• Oral hygiene habits

• Regular dental exams to monitor your oral health

• Regular dental cleanings

With proper care, both types can last many years.

4. Aesthetic Considerations

One of the biggest differences between white and silver fillings is appearance. White composite fillings are virtually invisible, making them ideal for patients concerned about their smile.

For patients investing in cosmetic treatments such as professional teeth whitening or Invisalign clear aligners, tooth-colored fillings provide a more seamless look.

5. Are Silver Fillings Safe?

Amalgam fillings have been widely used and studied for decades. However, many patients today prefer composite fillings due to aesthetic reasons and the desire for mercury-free restorations.

Your dentist can help determine which material is appropriate based on your individual case.

Conclusion

Both white and silver fillings effectively restore teeth affected by decay. However, many patients prefer white composite fillings for their natural appearance and modern benefits.
