The Impact of Amalgam Phase Out

The phase-out of dental amalgam is one of the most significant shifts in modern dentistry, with profound implications for clinical practice, education, and public health. The European Union’s decision to ban dental amalgam from January 1, 2025 (now postponed)—five years earlier than expected—has sparked debate across the profession, particularly regarding its impact on NHS dentistry, dental education, and clinical decision-making.

Two key papers highlight the challenges and opportunities presented by this transition:

"Amalgam Ban May Hasten NHS Dentistry’s Demise" (British Dental Journal, 2024) examines the impact of the ban on NHS dentistry. The British Dental Association (BDA) warns that alternative materials like composite resins are more expensive and time-consuming to place, potentially worsening access to care, especially for vulnerable populations. With NHS dentistry already under financial and workforce pressure, the abrupt removal of amalgam may exacerbate service limitations and increase treatment costs.
"End of the Road for Dental Amalgam?" (Dental Update, 2024) focuses on the educational and clinical implications of the ban. The paper highlights that many dental schools have reduced or eliminated amalgam training, leaving a new generation of dentists unprepared to place or remove amalgam restorations. The authors emphasize the need for curriculum updates to ensure graduates are proficient in modern restorative techniques, particularly with composite and glass ionomer materials.

Both papers agree that while the environmental and health concerns surrounding mercury have driven this ban, the transition must be carefully managed to prevent negative consequences for patient care and professional training. Without proper funding, planning, and adaptation, the removal of amalgam could strain NHS services and leave dentists unprepared for real-world clinical demands.

This discussion highlights the complex interplay between regulation, clinical practice, and education, underscoring the need for a structured and well-supported approach to ensure a smooth transition to mercury-free dentistry

Here is a summary of the two papers:

Aspect	Paper 1: Amalgam Ban May Hasten NHS Dentistry’s Demise (British Dental Journal, 2024)	Paper 2: End of the Road for Dental Amalgam? (Dental Update, 2024)
Main Focus	Impact of the EU amalgam ban on NHS dentistry, costs, and patient access.	Implications of the EU's proposal to phase out dental amalgam by 1 January 2025, focusing on education and clinical practice.
EU Amalgam Ban	The ban takes effect 1 January 2025, five years earlier than expected.	The EU proposes a complete phase-out of dental amalgam by 1 January 2025.
Impact on Dental Education	Not specifically addressed.	Concerns over dental education: Some dental schools have ceased teaching amalgam techniques, leading to graduates lacking skills in placing amalgam restorations. UK practitioners continue to use amalgam extensively, highlighting a gap between education and practice.
Clinical Practice Implications	Increased costs and longer treatment times with alternative materials like composites. Potential worsening of NHS access issues.	Disparity between training and practice: New graduates may be unprepared for clinical scenarios involving amalgam. Need for curriculum updates to ensure graduates are proficient with current materials and techniques.
Regulatory Context	UK faces supply chain and cost disruptions due to EU regulations. BDA warns no funding is in place to support the transition.	Minamata Agreement (2013): 147 countries agreed to minimize mercury use, affecting dental amalgam. Previous restrictions: Since 1 July 2018, amalgam use has been banned in pregnant women and children under 15.
Health & Environmental Concerns	Amalgam is considered a safe, durable material with a long history of clinical use. No proven health risks at current exposure levels.	Global efforts to reduce mercury usage due to environmental and health concerns.
Industry & Professional Reactions	British Dental Association (BDA) warns that NHS dentistry is already in crisis, and this ban will worsen access issues. Calls for urgent government intervention.	Concerns about the readiness of new graduates to handle amalgam restorations in practice. Emphasis on the need for educational reforms to align training with evolving clinical practices.
Alternative Restorative Materials	No alternative matches amalgam’s speed, durability, or affordability.	Educational focus should shift towards composite materials and other alternatives to ensure competency in current restorative techniques.
Final Message	The early amalgam ban could accelerate the collapse of NHS dentistry if funding and workforce solutions aren’t found.	Dental education and clinical practice must adapt to the impending phase-out of amalgam to ensure future practitioners are adequately prepared.

Key Messages

The EU is banning dental amalgam from January 2025, and the UK will face disruptions in supply and costs.
Amalgam is critical for NHS dentistry due to its low cost and ease of use, but alternative materials take longer to place and are more expensive.
Mercury toxicity and environmental concerns are the primary drivers of the ban, but the scientific debate over health risks continues.
Northern Ireland received a 10-year exemption, but the rest of the UK must prepare for higher costs and service pressures.
The British Dental Association (BDA) warns that NHS dentistry is already struggling, and the ban could worsen patient access and service sustainability
