When mercury fillings have to be removed?

  • Decay around amalgam filling.

  • Fractured tooth with an amalgam filling.

  • Root canal treatment for a tooth with an amalgam filling.

  • Burning sensation in the mouth, which could be a result of an amalgam filling.

  • Patient's allergy to mercury or amalgam ingredients.

  • Aesthetic appearance does not satisfy the patient.

What needs to be done to safely remove amalgam fillings:

The challenge you face when you have your old silver fillings removed is you may ingest some mercury in the process. Thus, the mercury can travel through your digestive tract to the rest of your body, possibly affecting your immune system and increasing the level of heavy metal toxicity in your body. As a result, you could suffer appetite loss, anemia, lower resistance to infection, and other mercury related symptoms.

To address this issue proactively, so the risk of mercury poisoning during the procedure is minimized, removing amalgam fillings involves a carefully planned procedure. Not only professional training is required, but also the use of unique technology:

Safety glasses

Safety glasses are put over your eyes to protect them.


We have you breathe pure oxygen through a nasal cannula (tube). This will minimize you are breathing the air right around your face, which is full of mercury vapor. Your nose will be covered with a dental mask to help keep the mercury vapor from going into your nostrils.

Rubber dam

A rubber dam or isolate will be placed over your mouth. This is a sheet of rubber that helps keep the mercury from going down your throat.

Cold water

Copious amounts of cold water will be constantly squirted on the filling as it’s being drilled out, to keep the temperature down. To decrease the amount of vapor, we section the fillings out in chunks as opposed to grinding it out. We use an electric drill for two reasons: First, because it cuts so much more efficiently than an air turbine. Second, because it turns at slower revolutions per minute, there is less heating of the tooth and less mercury vapor.

High-speed suction device

A High Volume Suction device will be used. This suction pulls all particles away from the tooth as the filling is being drilled out.

Charcoal and chlorella

Powdered charcoal and chlorella are placed in your mouth under the rubber dam. Both these substances can absorb mercury particles before they get absorbed into your system.

Minimum drilling

The fillings will be taken out with as little drilling as possible, in as large chunks as possible, to minimize the amount of mercury the vapor released into the air.



4x magnifiers to see minute details in the tooth will be used. This could include faint cracks and leaking crowns or fillings. The dentist can also make sure that the new crown or filling fits perfectly. Trying to do this without magnification makes it harder to get perfect results. Problems areas in the gums are more visible under magnification than with the naked eye.
