At Castle Dental, we believe dental care should protect not just your teeth, but your overall well-being.

That’s why we offer advanced, mercury-free white fillings that treat mild decay, small cracks, or worn enamel without compromising your health or the appearance of your smile.

Crafted from high-quality composite resin, white fillings are virtually invisible, gentle on teeth, and free from metal. They bond securely to your natural tooth structure, allowing us to preserve more of your healthy enamel and making them a safer, more modern alternative to traditional silver amalgam fillings.

Why choose white fillings?

White fillings do more than just repair your teeth; they support long-term oral health and peace of mind.

Mercury-free and metal-free

Amalgam fillings are about 50% mercury by weight and may also include tin, silver, and copper. The resin we use for white composite fillings is biocompatible, making it safe for your oral environment and your overall health.

Practically invisible

Unlike silver fillings, which darken over time, white fillings match the natural colour of your teeth. Once in place, they’re nearly impossible to detect—even in well-lit photos or close-up conversations.

Minimally invasive

Because composite resin bonds directly to your enamel, we can remove less natural tooth structure during placement. That means healthier teeth, stronger structure, and a longer-lasting result.

Reduced sensitivity

Composite resin doesn’t conduct heat or cold like metal does. This helps reduce temperature sensitivity after treatment, so sipping coffee or enjoying ice cream is far more comfortable.

Strong and durable

Today’s resin materials are incredibly tough, resilient enough for molars and everyday chewing. They can also be shaped and polished to mimic the natural contours of your tooth.

Easily repairable

Unlike metal fillings that require full replacement if chipped, white fillings can often be repaired directly. We simply add more resin and reshape, saving time, cost, and tooth structure.

A natural-looking fix for old fillings, too

If you’re concerned about the appearance or contents of your existing amalgam fillings, we can help. White fillings can often be used to replace old or damaged amalgam fillings.

Frequently asked questions

What to expect — Your questions answered

Are white fillings safe?

Yes. Composite resin fillings are metal-free and mercury-free, and are considered very safe for all patient groups. They’re also kinder to the tooth structure and surrounding tissues.

How long do white fillings last?

With good oral hygiene and regular check-ups, white fillings can last many years. Their durability now rivals that of traditional amalgam, especially when placed using modern bonding techniques.

Can I replace my silver fillings with white ones?

In most cases, yes. Our dentists can assess your existing fillings and determine whether a safe replacement is possible. Many patients choose to switch for both cosmetic and health-related reasons.
