What Are White Fillings?

White fillings, also called composite fillings, rose to popularity because of their natural colour that blends perfectly with the teeth. They are perfect for patients who are conscious about the way they look and who don’t want noticeable fillings, such as the silver amalgam fillings.

Make Up of White Fillings

Composite fillings are made with a resin base with materials such as quartz, silica, powdered glass and other ceramic particles. They are metal-free, which reduces the risk of having them placed in your mouth. They are available in various shades to match the colour of your natural teeth, although they might change in colour over time due to stains.

White Fillings vs. Amalgam

White filling differs from amalgam way beyond their appearance, but this is often the first point of comparison between both. White fillings fit right into the natural colour, shape and texture of your teeth. Amalgam, on the other hand, will instantly look out of place in its silver colour, which may also contribute to your teeth darkening.

In terms of durability, amalgam has been known to last longer than composites. However, recent developments in the materials used to make white fillings certainly made up for their difference in their strength. Now, there are composites that are expected to last as long as the silver fillings.

Composites win right away when comparing them against amalgam in terms of versatility. They have more clinical uses. They can fill teeth eaten by tooth decay, fill gaps between front teeth, repair chipped or fractured teeth, repair worn dentition, enhance your teeth’s appearance through dental bonding, and more.

There are more metals in white fillings, unlike the mercury found in amalgam. This minimises the risk among patients who might be allergic or highly sensitive to metal. However, composites do contain chemicals that may also cause certain issues in the future. Still, composites can be considered safer for use than amalgam.

However, white fillings take more skills and time to be placed. They are also more expensive than silver fillings because of their materials. In terms of cost and time, amalgam would be a better choice.

Before placing the filling, certain preparations must be done. With composites, they require less work and are relatively less invasive than the preparations done for placing amalgam. In terms of tooth structure preservation, white fillings do fit the bill better.

Which Should You Choose?

White fillings are preferred for their white colour that led to a more natural appearance. They don’t present metal allergies or similar risks and can easily bond with teeth, requiring minimal drilling. On the other hand, the amalgam’s silver colour makes it look unsightly and they contain mercury, increasing their risk. It is durable, but new white fillings are made of stronger and longer lasting materials too. These only serve to boost the popularity of composites. You can discuss with your dentist about which option is most suitable for your dental situation, but it helps now that you know the differences between both fillings and what each option entails. A consultation with dental clinics such as The Smile Studio can go more smoothly.
