Removal of Amalgam
For a long time, amalgam restorations were the best material available to dentists and outperformed almost all other direct filling material. However, in recent years, research and improvement of composite filling materials (white fillings) have removed the need to place amalgam restorations and thus, have removed the inherent risks of amalgam.
Amalgam restorations are based on silver and mercury. Although the mercury content is fairly low, placing and removing amalgam restorations inevitably cause some to enter the bloodstream. Utmost care is taken in the process of amalgam removal with high-volume suction, tooth-isolation and protective equipment to minimise the amount of aerosol inhaled or liquid swallowed.
Amalgam restorations have also been strongly correlated with cracked teeth. Due to the increased amount of preparation required for retention of these metal fillings, the remaining tooth structure is often weakened. Over time, the contact force of chewing can cause cusps to fracture. At your dental exams, we check every amalgam restoration carefully to check for cracks and can advise you about the best method of treatment or filling replacement.
