‘Silver’ fillings, commonly used in dentistry for over a century, actually contain 50% mercury. The fillings also expand and contract with time, which can crack and erode the teeth. Since 1991, the World Health Organisation has recognised that mercury/silver fillings are the greatest source of mercury in humans. Careful removal is key to reducing ongoing exposure. However, it must be done extremely carefully to minimise vapour that is released on removal. We ensure that amalgam is removed as safely as possible using a rubber sheet (or “dam”) to collect the debris whilst using water cooling and high-volume evacuation. We then focus on replacing your fillings with more biocompatible, aesthetic and long-lasting alternatives such as resin or ceramic restorations.
