Why Choose Composite Over Amalgam?

When it comes to dental restorations, patients today have more choices than ever before. One of the most important decisions involves selecting the right material for a filling. For years, amalgam—commonly referred to as silver fillings—was the standard. However, composite fillings have emerged as a preferred option for many patients and dental professionals alike.

At Sweet Water Dentistry, we often recommend composite fillings because they offer not only excellent functionality but also superior aesthetics. Let’s take a deeper look at why you might want to choose composite over amalgam.

Aesthetic Advantages

One of the top reasons patients choose composite fillings is their appearance. Unlike the dark, metallic look of amalgam, composite fillings are tooth-colored and can be precisely matched to your natural enamel. This makes them ideal for visible areas of your smile.

Whether you’re filling a new cavity or replacing an old filling, composite resin allows you to maintain a uniform, natural-looking smile.

Less Invasive to Tooth Structure

Composite fillings bond directly to the tooth, which means less healthy enamel has to be removed during preparation. In contrast, amalgam fillings require a larger space to be carved out for mechanical retention. This more conservative approach with composite helps preserve your natural tooth structure and can lead to better long-term oral health.

No Metal, No Mercury

Amalgam fillings contain a mixture of metals, including mercury, which has been a concern for some patients despite its safety being backed by the American Dental Association (ADA). Composite fillings are completely metal-free and do not contain mercury, making them an excellent option for those who prefer a more holistic or biocompatible approach to dental care.

Bonding Strength

Composite material bonds directly to the tooth’s surface using a special adhesive. This creates a secure seal that helps strengthen the remaining tooth and protect it from future decay. It also helps reduce the chance of leakage, which can occur if the margins of a filling begin to break down.

Amalgam, on the other hand, does not bond to the tooth. It is packed into place and relies on the shape of the cavity to stay secure, which can result in gaps or expansion over time.

Temperature Sensitivity & Cracking

Amalgam can expand and contract with changes in temperature—such as when you eat something hot or cold. Over time, this movement can cause tiny cracks in your tooth, which may eventually lead to larger fractures or the need for more extensive dental work.

Composite materials expand and contract at rates similar to your natural tooth enamel, making them less likely to cause cracking or damage.

Repairability

If a composite filling becomes worn or chipped, it is often possible to repair it by adding more material. Amalgam fillings usually have to be removed entirely if they become damaged, which can require more drilling and tooth removal.

Suitable for a Wide Range of Restorations

Composite resin isn’t just for filling cavities. It can be used for:

• Repairing chipped or broken teeth
• Reshaping teeth
• Closing small gaps between teeth
• Cosmetic bonding procedures

Its versatility makes it a great option for patients looking for both function and aesthetic improvement.

Are There Any Downsides?

While composite fillings offer many benefits, it’s fair to note that they typically cost more than amalgam fillings and may take slightly longer to place. The application process is more technique-sensitive and involves layering and curing steps.

However, most patients find that the aesthetic and functional advantages far outweigh the minor extra investment of time or cost.

What’s Right for You?

At Sweet Water Dentistry, we tailor every treatment plan to the individual. Dr. Greer will carefully evaluate your dental needs, the location and size of the cavity, and your personal preferences when recommending the best filling material for your situation.

If you’re looking for a solution that is safe, natural-looking, and durable, composite fillings are a strong choice.
