20 Questions to Ask Before Your Mercury Filling Removal Appointment

This is the most important single question. Rubber dam is the cornerstone of patient protection during SMART removal — it physically prevents mercury particles and vapor from entering your airway. There is no acceptable substitute. If the answer is "sometimes" or "when the patient requests it," that's a concern.

Sectioning (cutting into large pieces and lifting them out) dramatically reduces the mercury vapor surface area released compared to grinding. A dentist who doesn't know what you mean by this question has likely not received SMART training.

HVE captures vapor and particles at the source. A standard saliva ejector (the small tube under your tongue) does not. Ask whether they have a dedicated assistant to operate it throughout the procedure — this requires two people working simultaneously.

Both HEPA and activated carbon are required. HEPA captures particles; activated carbon captures mercury vapor (a gas). A HEPA-only unit doesn't filter mercury vapor. Ask when the filters were last replaced.

Some SMART practitioners provide a nasal cannula delivering clean oxygen so the patient isn't breathing room air during the procedure. This is the fifth protective layer and, while not in every practice, is a meaningful additional measure.

Legitimate IAOMT SMART certification is verifiable at iaomt.org/find-a-dentist. IAOMT membership is not the same as SMART certification — ask which one applies.

Training without volume means limited practical experience. A provider doing 5–10 SMART removals per week is meaningfully more practiced than one doing 5 per year.

IAOMT SMART, your own protocol, or something else? Understanding their framework helps you evaluate their approach against established standards.

Essential. Should separate: removal fee, protocol premium, replacement material, and any consultation or diagnostic fees. Anything less than itemized is a red flag.

Know before you go what's being submitted, what the expected coverage is, and what your out-of-pocket will be after payment.

Important to ask before the appointment. Most practices accept HSA/FSA. Not all offer payment plans. CareCredit acceptance is common at biological practices.

Sometimes removing a large amalgam reveals additional decay or a cracked tooth that requires more extensive work. Ask for a probability assessment of this happening for your specific fillings.

The answer should reference your specific clinical situation — filling size, tooth location, occlusal forces. A blanket "we use ceramic for everything" or "composite is always fine" without clinical reasoning is not ideal.

Ceramic means 2+ visits, a temporary restoration between appointments, and significantly higher cost. Understand the full picture before agreeing.

Some biological dentists offer blood testing to evaluate which composite or ceramic materials are most biocompatible for a specific patient. This is optional and adds cost — understand what it involves if offered.

Some practitioners prefer one per session; others do all at once. Both can be appropriate. Know what to expect for scheduling and total number of visits.

Even if you don't think you need it, know your options. Some patients prefer nitrous oxide for comfort during longer appointments.

Ask specifically what's normal and what should prompt a call. Setting expectations before the appointment reduces anxiety afterward.

Most practices warranty composite placements for 1–2 years. Understand what's covered — a failed restoration within warranty should be repaired at no cost.

Some practitioners recommend pre-procedure nutritional protocols or have specific pre-appointment instructions. Better to ask than to discover you missed something important.
