Treatments - Mercury Free

Our position on the use of mercury in dental restorations:

  • Because of its toxicity we do not place any new restorations containing mercury.
  • If mercury containing fillings (amalgam) need to be removed because they are clinically failing or cosmetically objectionable, we will remove them carefully ensuring minimal further murcury enters the patients' system.
  • We ensure that mercury fillings removed in this way are stored safely and removed from the premises by a registered waste disposal company.

Amalgam Removal Process

Organic powdered charcoal in filtered water. This provides a large surface area of carbon which is an excellent absorber of heavy metals such as Mercury.

Powdered charcoal lining the mouth, pharynx, oesophagus and stomach, any mercury vapour which escapes the dam sealant is likely to be absorbed by the carbon and excreted thereby minimising absorption by the patient.

Dentist and nurse wear a heavy metal filtration mask and eye protection during the procedure.

Carbon filter and suction system scavenges Mercury vapour from the air in the surgery.

Dental non latex dam and sealant is used to help seal the mercury amalgam filled teeth from the rest of the mouth while the metal is removed.

Medical oxygen is breathed through the nose during the removal of the amalgam to avoid re-breathing mercury vapour.

Each filling is carefully cut around in order to minimise Mercury vapour release.

The remaining filling is levered out from the cavity.

Loose pieces of filling are caught in the dam.

They are them placed in an airtight Amalgam Safe until they are picked up by a toxic waste disposal company.

The cavities are then treated in order to receive and bond with the restorative material, either composite resin or a Cerec ceramic inlay.

Light is used to set/harden composite filling material and to bond Cerec ceramic inlays to the remaining tooth.
