Silver or White Fillings – Everything You Need to Know

02 October 2023

Dental health is a vital aspect of overall well-being, and when it comes to dental fillings, choosing the right material is crucial. Silver (amalgam) and white (composite) fillings are the two primary options available, each with its own set of characteristics and considerations. In this comprehensive guide, we’ll dive deep into the world of dental fillings to help you make an informed decision about which one is better suited to your unique oral health needs.

Fillings Comparison

Silver Fillings White Fillings
Highly durable and long-lasting. Less durable than silver fillings, may require replacement sooner.
Cost-effective, often more affordable. Generally more expensive than silver fillings.
Strong and resistant to wear and tear. Bond directly to the tooth, providing added support.
May expand and contract with temperature changes. May stain or discolour over time, especially with certain foods/drinks.
May not be suitable for visible areas due to aesthetics. Aesthetic appeal – they blend with natural teeth.

Key Facts about Silver Fillings (Amalgam)

  • Composition: Silver fillings, also known as amalgam fillings, are a blend of metals, including silver, tin, copper, and mercury. The use of mercury has raised some concerns over the years, but it is generally considered safe when used in dental amalgam in trace amounts.
  • Durability: One of the standout qualities of silver fillings is their durability. They are renowned for their longevity and can withstand the forces of chewing and grinding for several decades.
  • Cost: Another advantage of silver fillings is their cost-effectiveness. They are often more affordable than their white counterparts, making them an attractive option for those on a budget.
  • Appearance: However, silver fillings have a notable drawback: their dark colour. They are easily noticeable when you open your mouth, which can be a concern for individuals who prioritise aesthetics.

Key Facts about White Fillings (Composite)

  • Composition: White fillings, also called composite fillings, are composed of a resin material that can be precisely matched to the colour of your natural teeth. This makes them an ideal choice for filling cavities in visible areas.
  • Aesthetics: Perhaps the most significant advantage of white fillings is their aesthetic appeal. They seamlessly blend with your natural teeth, making them virtually indistinguishable.
  • Bonding Process: White fillings bond directly to the tooth, providing additional support and reducing the risk of fractures. This bonding process can also help to preserve more of your natural tooth structure.
  • Strength and Durability: While white fillings are durable and strong, they may not last as long as silver fillings. Their lifespan can vary depending on factors such as the size of the filling, the location in the mouth, and your oral hygiene habits.

Making the Right Choice

When it comes to making the right choice between silver and white fillings, your dentist is your best ally. They can assess your specific dental needs, consider your oral health history, and recommend the most suitable option.

Balancing cost considerations with aesthetic preferences is often a key factor in the decision-making process. While silver fillings may be more affordable, many patients prioritise the natural appearance offered by white fillings.


In the ongoing debate of silver vs. white fillings, there’s no one-size-fits-all answer. Your choice will ultimately depend on your unique circumstances, priorities, and preferences. While silver fillings excel in terms of durability and cost-effectiveness, white fillings shine when it comes to aesthetics and blending with your natural teeth.

Remember that regardless of the type of filling you choose, maintaining good oral hygiene practices and scheduling regular dental check-ups are essential for ensuring the longevity and health of your dental fillings.

In conclusion, make an informed decision about your dental fillings, and enjoy a healthier, more confident smile. Your dentist is your partner in this decision-making process, and together, you can determine the best filling option to meet your oral health needs and aesthetic desires.
