White Fillings vs. Amalgam Fillings: Making the Right Choice for Your Smile
When it comes to restoring your smile, choosing the right dental filling is essential. White composite fillings offer a natural, aesthetic solution that blends seamlessly with your teeth, while amalgam fillings provide a durable, cost-effective option with a long history of use. At Skymark Smile Centre, we help you navigate the pros and cons of each type to ensure you make the best decision for your oral health. Whether you're concerned about aesthetics, safety, or durability, understanding the differences between these fillings will help you choose the most suitable option for your smile.
Key Takeaways
- Aesthetic Consideration: White fillings are ideal for those prioritizing a natural look, as they blend seamlessly with your teeth.
- Durability: Amalgam fillings are stronger, especially for back teeth, but less aesthetically pleasing.
- Safety: White fillings are mercury-free, making them a safer choice for patients concerned about toxicity.
- Cost: White fillings are more expensive, but their cosmetic appeal and durability often justify the cost.
White Fillings vs Amalgam: What’s the Difference?
White Fillings (Composite Fillings)
White fillings are composed of a blend of resin and finely ground glass particles. This composite resin is not only strong but is also designed to match the natural colour and translucency of teeth. One of the primary advantages of white fillings is their ability to blend seamlessly with your natural teeth, making them almost invisible.
Amalgam Fillings
Amalgam fillings, on the other hand, are made from a mixture of metals, including mercury, silver, tin, and copper. Although they have been used in dentistry for over a century due to their strength and durability, they differ greatly in appearance from natural teeth. Amalgam fillings are silver in colour and can be noticeable when you smile or speak, which may be less aesthetically appealing to some patients.
Strength & Longevity of Fillings
The strength and longevity of dental fillings depend on the materials used and recent technological advancements in composite resins.
| Property | White Fillings | Amalgam Fillings |
|---|---|---|
| Durability | Moderate durability | High durability |
| Ideal for | Front teeth, visible areas | Back teeth, molars |
| Lifespan | 5-10 years (recent advances) | 15+ years |
| Resistance to Biting Pressure | Moderate | High |
While white fillings have made significant strides in durability, amalgam fillings remain known for their strength, especially when subjected to the substantial forces encountered by back teeth.
Safety & Toxicity: Myths vs Facts
Amalgam fillings contain mercury, which raises concerns for some patients. Despite this, numerous studies have shown that the mercury in amalgam fillings poses no significant health risk to most individuals. However, certain populations, such as pregnant women or people with kidney concerns, may opt for mercury-free alternatives.
White Fillings, on the other hand, are mercury-free and are often chosen by patients concerned about the potential toxicity of amalgam fillings.
“White fillings are a great option for patients concerned about mercury. They offer a safe, durable, and aesthetically pleasing alternative.”

Aesthetic Appeal: Which Is Better for Your Smile?
For many patients, the visual appeal of dental fillings is a top priority, especially when the fillings are placed in visible areas of the mouth.
White Fillings: These are the ideal choice for those seeking a discreet solution. They match the natural colour of your teeth and blend in seamlessly, making them nearly invisible in areas such as the front teeth.
Amalgam Fillings: The silver colour of amalgam fillings can be noticeable when you smile or talk. For patients who value the cosmetic aspect of their dental work, this may be a concern.
If appearance is a priority, white fillings are the clear choice.
The Filling Application Process
White Fillings
The application process for white fillings is more involved compared to amalgam fillings. After cleaning the cavity, your dentist will apply the composite resin in layers, using a special light to harden each layer. The dentist then sculpts the material to match the natural contours of your tooth. This process tends to take more time due to the layering and curing steps involved.
Amalgam Fillings
Amalgam fillings are applied quickly. The dentist removes the decayed portion of the tooth, packs the amalgam material into the cavity, and allows it to solidify. Once hardened, the filling is shaped to fit the tooth. This process generally takes less time than applying white fillings.
Cost Comparison: White Fillings vs. Amalgam
| Filling Type | Average Cost Range | Insurance Coverage |
|---|---|---|
| White Fillings | $150–$300 per filling | Partial to full coverage (depends on policy) |
| Amalgam Fillings | $75–$150 per filling | Often fully covered |
White fillings tend to be more expensive due to the materials used and the time required for their application. Amalgam fillings are more affordable, making them an attractive option for patients on a budget.
Maintenance and Repair
Both white and amalgam fillings require regular maintenance to ensure their longevity.
White Fillings: While advancements in composite materials have improved their durability, white fillings may need to be replaced or repaired over time, especially when subjected to heavy chewing forces.
Amalgam Fillings: Known for their durability, amalgam fillings often last longer without requiring repairs. However, they can become discoloured over time, turning greyish.

FAQ
What are the main differences between white fillings and amalgam fillings?
Answer: White fillings (composite fillings) are made of resin and glass particles, offering a natural, tooth-like appearance. Amalgam fillings, made of metal alloys including mercury, are more durable but can be visible due to their silver colour. White fillings are ideal for visible areas, while amalgam fillings are best for back teeth where durability is more important.
Which filling is better for my teeth, white fillings or amalgam?
Answer: The best filling depends on your specific needs. White fillings are a great choice for front teeth due to their aesthetic appeal, while amalgam fillings are better suited for molars that experience high chewing pressure. Consult your dentist to determine which option is right for you.
Are white fillings safer than amalgam fillings?
Answer: Yes, white fillings are considered safe and are mercury-free, making them a good option for patients concerned about the potential risks of mercury exposure in amalgam fillings. Most research supports the safety of amalgam fillings for most people, but if you are concerned, white fillings may be a better choice.
How long do white fillings last compared to amalgam fillings?
Answer: White fillings typically last between 5 to 10 years, depending on their location and how much pressure they experience. Amalgam fillings last longer, often up to 15 years or more, but may become discoloured over time. Both types require regular maintenance and monitoring by your dentist.
What is the cost difference between white fillings and amalgam fillings?
Answer: White fillings are generally more expensive than amalgam fillings due to the materials and the more complex application process. On average, white fillings cost $150 to $300 each, while amalgam fillings cost $75 to $150 each. However, many insurance plans may cover part of the cost for both types.
