The recent decision by the European Parliament to ban dental amalgam from January 1, 2025, marks a significant shift in dental practices, especially in the UK. Dental amalgam, commonly used for NHS permanent fillings, has been a mainstay in dentistry for over 150 years due to its durability and effectiveness. However, this decision to phase out its use raises important discussions about the negatives of amalgam fillings.

Negatives of Amalgam Fillings

1. Mercury Content: Dental amalgam is a metal mixture containing liquid mercury, along with a combination of powdered silver, copper, and tin. The presence of mercury has long raised health and environmental concerns. Over time, the mercury in amalgam can release vapours, potentially leading to mercury poisoning with symptoms like headaches, anxiety, and digestive issues.
2. Environmental Impact: Mercury is a global pollutant and a severe neurotoxin, which can cause significant environmental harm. The phase-out of amalgam is part of broader efforts to reduce mercury use globally.
3. Aesthetic Concerns: Amalgam fillings are silver and can be more noticeable than tooth-coloured alternatives. This can be a cosmetic concern for patients who prefer fillings that blend in with the natural color of their teeth.
4. Longevity vs. Alternatives: While amalgam is known for its durability, alternative restorative materials that are more aesthetically pleasing and do not contain mercury are now available. However, these alternatives may not always match amalgam in terms of the speed of placement or longevity, posing a challenge for dental practices.
