In recent years, the conversation around amalgam fillings, commonly referred to as metal or silver fillings, has intensified. Comprising about 50% mercury, with the remainder being a mix of silver, tin, and other materials, these fillings have been a staple in dental restoration for decades. However, the presence of mercury—a highly toxic substance—has led many to question their safety and consider alternatives. This article aims to shed light on the issue, helping you make an informed decision about whether to keep, remove, or avoid amalgam fillings.
Understanding Amalgam Fillings
Amalgam fillings have been utilised for over a century, prized for their durability and longevity compared to other materials. They are often called “silver fillings” due to their appearance. Despite their widespread use, the fact that they contain mercury raises concerns due to mercury’s toxicity and potential health risks, particularly its effects on the central nervous system.
The Case for Removal
The debate around the safety of amalgam fillings centres on the mercury content. Mercury is known to be extremely toxic, and its use in a procedure that places it within the human body has been increasingly scrutinised. Critics argue that no level of mercury exposure is safe and that the potential risks, especially incorrect placement or removal, outweigh the benefits.
Moreover, the “human battery” effect—where electrical currents are generated between metal fillings via saliva, akin to a battery—has also been a point of concern. Although evidence on how this affects living tissues is scarce, the theoretical risk has prompted some to reconsider the presence of amalgam fillings in their mouths.
As an alternative, white fillings, made from composite materials, offer several benefits. Aesthetically, they are superior, able to match the natural colour and shade of your teeth. They also avoid the use of mercury, addressing health concerns associated with amalgam fillings. However, it’s worth noting that, historically, white fillings were not as durable as their amalgam counterparts, although advances in dental technology have significantly improved their longevity and strength.
If you’re contemplating the removal of amalgam fillings, it’s crucial to gather all the facts. The General Dental Council maintains that once in place, amalgam fillings do not pose a significant health risk. However, the process of removal must be handled with care to minimise exposure to mercury vapour. Dental practices equipped with the necessary tools and expertise, such as the Smiles Centre, can safely remove these fillings, reducing the risk of mercury poisoning.
The decision to remove amalgam fillings is personal and should be made after thorough research and consultation with dental professionals. While the potential health risks associated with mercury are a significant concern for many, it’s essential to weigh these against the benefits of amalgam fillings, including their durability and cost-effectiveness. For those opting for removal, choosing a reputable dental practice experienced in safe removal techniques is paramount to minimise health risks.
In the end, whether to remove, replace, or retain amalgam fillings is a decision that should be made based on a comprehensive understanding of the facts, personal health considerations, and discussions with trusted dental care providers.
