Sound Amalgam Fillings Do Not Need Routine Preventive Removal

The FDA¹ does not recommend removing an amalgam filling when it is in good condition and a dental professional finds no decay beneath it. Removing an intact filling can unnecessarily remove healthy tooth structure and temporarily increase exposure to mercury vapor.¹

The idea to correct: removal is automatically preventive

The FDA¹ says intact amalgam fillings should not be removed solely to prevent disease or a health condition unless a health professional considers removal medically necessary. This includes people in groups it identifies as potentially more susceptible to mercury exposure.¹

Ask the dentist to explain the reason for any proposed replacement. Is it recommending treatment for a particular finding, or are you discussing your concern about the material? Keep those questions in the consultation so you understand what decision you are making.

Ask the dentist to confirm the condition of the filling and whether there is decay beneath it. The FDA¹ recommendation depends on that professional assessment.¹

A new filling is a separate decision

For a new filling, FDA¹ advice identifies pregnancy or planned pregnancy, nursing, mercury allergy, neurological impairment and kidney dysfunction as circumstances to discuss. For people in its identified higher-risk groups, it recommends avoiding new amalgam where possible and appropriate.¹

Tell the dentist about your health history before choosing a material. If any of those circumstances applies, ask how it affects your options.

Take symptoms to care without deciding their cause

If you believe you have had an adverse reaction to an amalgam filling, the FDA¹ advises discussing it with a dentist or physician. It also provides a MedWatch reporting route.¹

Describe what happened, when it started and any treatment you have had. Ask who should assess the concern and how the dental findings fit with any medical assessment. Keep the explanation and proposed next step with your appointment notes.

Leave with the reason for the plan

Ask which fillings need treatment, what finding supports that decision and what the alternatives would involve. If no replacement is recommended, ask what the dentist wants to check at future visits. Request clarification before agreeing to a plan you cannot explain in your own words.
