Mercury Changeover

When removing Mercury/Amalgam/Silver fillings mercury vapour is released, and as we take a holistic approach we following a protocol designed to protect you.


We recommend that prior to removing mercury fillings you consider taking such as selenium, magnesium, zinc, B vitamins or as suggested by your natural health practitioner.

Rubber Dam:

When removing a mercury fillings we will place a rubber dam over the mercury filled tooth. When a rubber dam is placed over the tooth this tooth will be the only surface exposed, all other areas of your mouth will be protected. This is to prevent fragments of Mercury being swallowed or absorbed by soft tissue.


A close fitting Oxygen mask is placed over your nose and oxygen is supplied to your body with enough pressure to prevent inhalation of any Mercury Vapour released during the filling removal.

Special Burs:

Tungsten carbide burs are used for the removal as they create less Mercury Vapour.


It has been demonstrated that massive water flow onto the tip of the cutting bur also reduces the level of mercury vapour created in the cutting process. All water in our surgery is filtered.

Drill Hand Pieces:

The latest technology  hand pieces we use have 4 jets of water aimed at the work surface of the tooth, rather than the normal 3 jet hand piece once again providing massive water flow.

Air Filtration and Extractors:

Each surgery and room within the practice is equipped with air filtration and high volume extractor fans that totally changes the air in the room 12 times an hour to eliminate mercury vapour inhalation.

A uses an IQ Air Mercury FlexVac air filtration machine with a flexible vacuum arm which captures bacterial aerosols and mercury vapour from the drilling process.

Environmental Dentistry:

We have also installed filters that extract all the Mercury from the waste after drilling so that no Mercury from our practice is fed into the environment. And filters on the air extraction system  filter out Mercury vapour.
