Mercury-Safe Removal of Silver (Amalgam) Fillings
We remove old silver amalgam fillings under a protocol designed to limit exposure to mercury vapour and particles: rubber-dam isolation, high-volume suction at the tooth, copious water, and sectioning the filling out in pieces rather than grinding it away. The tooth is then restored with ceramic or a BPA-free composite.

What happens
The tooth is isolated with a rubber dam so nothing enters the mouth.
High-volume suction is placed at the tooth, with continuous water cooling.
The amalgam is sectioned and lifted out in pieces rather than being drilled through.
The cavity is cleaned, and the tooth restored with a bonded ceramic onlay or a BPA-free composite.
Amalgam is roughly half mercury by weight, bound in an alloy. Sound amalgam fillings that are not failing can reasonably be left alone — removing a filling always costs some tooth structure. The clinical reasons to replace one are the usual ones: decay underneath, a crack in the tooth, a fractured margin, or a filling so large the remaining walls are at risk.
If you would prefer metal-free restorations for your own reasons, that is a legitimate choice and we will discuss what each tooth needs. What we will not do is tell you that removing sound fillings will treat an unrelated medical condition — there is no evidence for that, and you should be wary of anyone who says otherwise.

Questions
Why remove amalgam in pieces rather than drilling it out?
Drilling through amalgam generates heat, vapour and fine particles. Sectioning it into chunks and lifting them out under suction produces far less of all three.
What replaces the filling?
Either a bonded ceramic onlay milled in the clinic, or a BPA-free composite, depending on how much tooth is left. We show you both options with the scan on screen.
Should I have all my amalgams removed?
Not routinely. Sound, sealed fillings can be left in place and monitored; removal always sacrifices some tooth. We will tell you which of yours are actually failing.
Are you IAOMT certified for amalgam removal?
No, and that is a deliberate choice rather than an oversight — we do not maintain the certification. What we can tell you is exactly what our own removal protocol does, which is the part that affects you: the tooth is isolated under a rubber dam so nothing enters your mouth or is swallowed, high-volume suction runs throughout to capture vapour and particles at source, and the filling is sectioned into pieces and lifted out whole rather than ground away, which generates far less vapour than drilling it out. The one element of the certified protocol we do not use is an oxygen concentrator. If certification matters to you, ask at consultation and we will tell you plainly where we stand.
