Different Types of Dental Fillings and How to Choose the Best One

Adrian Franco • January 8, 2025

Dental fillings are one of the most common restorative procedures in modern dentistry. If you have a cavity or damage to your teeth, fillings can restore both function and aesthetics. However, with several types of dental fillings available, it’s essential to understand their differences to make an informed decision that suits your needs.

At The Dental Boutique, we believe in educating our patients so they can choose the treatment best suited to their oral health goals. Here’s a comprehensive guide to the types of dental fillings and how to select the ideal one.

Types of Dental Fillings

1. Amalgam Fillings

Material: A mixture of metals including silver, tin, zinc, copper, and mercury.

Durability: Highly durable and long-lasting (up to 15 years or more).

Cost: Generally the most affordable option.

Appearance: Silver-colored, making them noticeable, especially in front teeth.

Best For: Back teeth where strength is more critical than appearance.

2. Composite Resin Fillings

Material: Tooth-colored resin made of a mixture of plastic and fine glass particles.

Durability: Lasts around 5–10 years with proper care.

Cost: Slightly more expensive than amalgam.

Appearance: Blends seamlessly with natural teeth for a discreet finish.

Best For: Visible teeth where aesthetics are a priority.

3. Ceramic Fillings (Porcelain)

Material: Porcelain that matches the natural tooth color.

Durability: Can last over 15 years; highly resistant to staining.

Cost: More expensive than composite fillings.

Appearance: Extremely natural-looking, providing a flawless finish.

Best For: Patients seeking an aesthetically superior and durable option.

4. Gold Fillings

Material: A mixture of gold and other metals.

Durability: Extremely durable, lasting up to 20 years or more.

Cost: The most expensive filling type.

Appearance: Distinct gold color that some patients find appealing.

Best For: Patients who prioritize longevity and don’t mind the noticeable appearance.

5. Glass Ionomer Fillings

Material: A mix of acrylic and a type of glass that releases fluoride.

Durability: Less durable, typically lasting around 5 years.

Cost: Comparable to composite fillings.

Appearance: Tooth-colored but not as natural-looking as composite.

Best For: Temporary fillings or fillings for children due to fluoride release.

Factors to Consider When Choosing the Best Filling

When choosing a dental filling, consider the cavity's location—composite or ceramic for visible teeth, and amalgam or gold for durable back teeth. Budget plays a role, with amalgam being cost-effective and ceramic or gold more expensive. For a natural look, opt for tooth-colored composite or ceramic. Gold and ceramic offer long-lasting durability, while amalgam balances cost and strength. Discuss allergies with your dentist if sensitive to metals. Good oral hygiene extends the life of all fillings, though composite and glass ionomer may need extra care.
