When it comes to restoring teeth affected by cavities, Main Street Dental offers several filling options to meet each patient’s needs. One of the most reliable and time-tested choices is the amalgam filling. Known for its strength and durability, amalgam has been used by dentists for more than a century to repair teeth and restore function. At our Newark, Delaware office, we continue to provide amalgam fillings as a trusted solution for patients seeking long-lasting cavity repair.

Amalgam fillings are sometimes called “silver fillings,” though they are made from a blend of metals. The mixture typically includes silver, tin, copper, and a small amount of mercury, which binds the metals together into a strong, stable material. This combination results in a filling that can withstand the forces of chewing and last many years.
Amalgam fillings are especially useful for repairing cavities in back teeth (molars and premolars), where biting pressure is greatest. They may not blend in with natural enamel like tooth-colored fillings, but they provide a dependable, affordable option for patients concerned about strength and longevity.
Our dentists may recommend amalgam fillings in the following situations:
While some patients prefer composite (tooth-colored) fillings for aesthetic reasons, amalgam offers several unique advantages:
Having an amalgam filling placed is a straightforward procedure that can usually be completed in a single appointment. Here’s what you can expect:
Once complete, the amalgam filling restores the tooth’s structure and prevents further decay.
One of the most common questions patients have about amalgam fillings concerns safety. Amalgam fillings contain a small amount of mercury, but extensive research from the American Dental Association, the U.S. Food and Drug Administration, and the World Health Organization confirms that amalgam is safe for most patients. The mercury is bound within the alloy, making the filling stable and non-toxic.
That said, patients who prefer not to have amalgam fillings can choose composite resin or other alternatives. At Main Street Dental, we respect your preferences and will explain all available options so you can make an informed decision about your care.
Amalgam fillings are among the longest-lasting dental restorations. On average, they last 10 to 15 years, though many patients have fillings that endure even longer. Factors that affect longevity include the size of the filling, the tooth’s location, and your oral hygiene habits. During regular exams, we’ll check your fillings for wear and determine when replacements may be necessary.
Regular visits for dental checkups and cleanings can help ensure your fillings stay strong and intact.
Proper care extends the life of any dental restoration, including amalgam fillings. We recommend:
If you prefer a more natural-looking option, we also offer composite resin fillings, which match the color of your teeth. These are often chosen for front teeth or visible areas where appearance matters most. Other options, such as porcelain or gold inlays and onlays, may also be recommended depending on your dental needs and goals.

Yes. If your amalgam fillings are worn, damaged, or if you’d like a more aesthetic option, we can replace them with composite or porcelain restorations.
Yes. Although composite fillings are increasingly popular, many patients still choose amalgam for its strength, durability, and affordability.
