The Problem with Old Metal Fillings
Tooth fillings made from metal amalgam were the standard for decades. But these silver-colored fillings expand and contract with temperature changes far more than natural teeth, creating tiny gaps that allow bacteria and food to leak in. Over time, this can lead to additional decay or damage.
As Los Gatos dentists, we prioritize materials and techniques that support your overall health—not just your teeth. Metal amalgam contains roughly 50% mercury by weight—a toxic metal that can travel through the body and accumulate in organs. While some claim it remains stable in fillings, many patients choose to avoid any potential risk by opting for mercury-free materials that are safer, healthier, and more biocompatible.
A Safer, More Attractive Solution
Modern filling materials—composite resin and porcelain—are engineered to match the color and texture of natural teeth while sealing the tooth more effectively than amalgam. As holistic dentists in San Jose, we choose these biocompatible materials because they bond directly to tooth structure, creating a strong, durable restoration that helps prevent future decay while blending seamlessly into your smile.
Composite vs. Porcelain Fillings
Composite resin fillings are made from a tooth-colored material reinforced with fine ceramic particles. They’re cost-effective, completed in a single visit, and polished to a natural luster. While they offer strong performance, they may gradually lose their shine, discolor, or wear down over time—especially in areas that handle heavy bite pressure.
Porcelain fillings, or ceramic restorations, are the most durable and lifelike choice. They resist stains, maintain their polish for years, and replicate the translucence of natural enamel. Because they are custom-crafted, they require two appointments—one to prepare the tooth and another to place the restoration—but the results are exceptionally long-lasting and highly aesthetic.
At Top Down Dental, we’ll help you select the right material for your oral health needs, cosmetic goals, and lifestyle so you get a filling that’s both functional and beautiful.
When a Filling May Not Be Enough
Sometimes, decay or damage can be too extensive for a filling to provide the needed strength and protection. Large cavities, cracks, or structural weakness in the tooth may cause a filling to fail prematurely. In these cases, our San Jose restorative dentist may recommend a dental crown, inlay, or onlay instead. These options offer more coverage and reinforcement, restoring the function and appearance of your tooth while reducing the risk of future damage. During your visit, Dr. Rana Alan will assess your tooth carefully and explain which treatment will best preserve your long-term oral health.
Comfortable, Efficient Treatment
Your filling appointment is designed for your comfort and convenience. After carefully numbing the area, we remove the decayed portion of the tooth, clean it thoroughly, and place your filling with precision. Composite fillings are completed in one visit, while porcelain fillings are placed once your custom restoration is ready from the dental lab. Most patients experience little to no discomfort during the procedure and only mild sensitivity afterward, which usually fades quickly.
Your Smile, Restored
Dental fillings don’t just fix a problem—they can also restore function, enhance appearance, and help prevent future dental issues. In this way, a single treatment can offer the combined benefits of restorative, cosmetic, and preventive dentistry. Whether you’re repairing decay, replacing old metal fillings, or improving the look of your smile, Dr. Rana Alan provides advanced, mercury-free solutions with an emphasis on both oral health and overall wellness.
