Silver amalgam dental fillings have been used for decades as a reliable solution for restoring teeth affected by decay. These fillings are known for their durability and affordability, continuing to play a role in modern dentistry despite the growing popularity of tooth-colored alternatives. Understanding the pros, cons, and safety of silver amalgam fillings can help patients make informed decisions about their and their family's dental care.
Silver amalgam fillings contain various metals, including silver, tin, copper, and mercury. This amalgamation forms a strong, long-lasting material that has been a staple in restorative dentistry for over a century. While newer materials, such as composite resins, have become increasingly popular for their aesthetic appeal, silver amalgam remains a trusted option in many dental practices. General dentists typically use amalgam fillings to restore molars and premolars, as the material can reliably withstand the significant chewing forces these teeth endure.
Silver amalgam dental fillings offer several distinct advantages, making them a valuable option for addressing tooth decay. Three of their most popular benefits include the following:
One of the most notable benefits of silver amalgam is its strength. These dental fillings can withstand the pressures of chewing and grinding without cracking. These fillings can last 10 to 15 years or more with proper care and maintenance.
Silver amalgam is generally more affordable than composite resin and gold. Its lower cost makes it accessible for patients seeking a budget-friendly solution to cavities. Moreover, patients will not have to worry about replacing these dental fillings any time soon, as they are durable and built to last.
The placement process for silver amalgam dental fillings is relatively straightforward and quick. For this reason, many general dentists recommend these fillings for larger cavities or situations requiring multiple fillings.
Silver amalgam fillings, while durable and cost-efficient, do have some drawbacks that may influence their appeal. A primary concern for many is their metallic appearance, which is more noticeable compared to tooth-colored composite fillings. For some patients, this can be a significant drawback, especially for fillings in visible areas of the mouth. Additionally, over time, amalgam fillings may cause a grayish tint to the surrounding tooth structure. While this discoloration does not affect the filling's functionality, it can impact the tooth's overall appearance.
The mercury content in silver amalgam fillings is a topic of frequent discussion. Mercury is used in amalgam to bind the metals together and create a stable, durable material. Once the filling hardens, the mercury is encapsulated within the mixture, minimizing its release.
The American Dental Association (ADA), the World Health Organization (WHO), and the U.S. Food and Drug Administration (FDA) have consistently supported the safety of silver amalgam fillings for the general population. However, a general dentist may advise certain groups — such as those with metal allergies or sensitivities — to explore alternative options.
For patients with existing silver amalgam fillings, routine dental exams ensure their integrity and function. Unless there is evidence of damage, decay, or other complications, the removal of intact amalgam fillings is generally not recommended.
