Amalgam Removal (SMART)

Why patients ask about amalgam removal

Traditional silver fillings, known as dental amalgam, are made of roughly half mercury blended with other metals. These fillings release small amounts of mercury vapor, and the amount rises during chewing and grinding and especially when a filling is placed or taken out. Patients look into removal for different reasons. Some want to lower their exposure, some are switching to materials their body may tolerate better, and some simply have old fillings that are cracked or breaking down. It helps to know where the evidence sits. The Food and Drug Administration has long considered amalgam acceptable for most adults, and in 2020 it recommended non mercury alternatives for groups who may be more sensitive, including pregnant women, nursing mothers, young children, and people with certain health conditions.

What safe removal looks like

Because drilling into a filling releases vapor and fine particles, the way it is removed matters a great deal. Biological dentists use a set of protective steps called the Safe Mercury Amalgam Removal Technique, or SMART, developed by the International Academy of Oral Medicine and Toxicology. In short, the tooth is isolated with a rubber dam, strong suction sits right at the tooth, you breathe clean air through a nasal mask, the filling is sectioned into chunks rather than ground away, and the room air is filtered the whole time. For the full step by step walkthrough, read our guide to the SMART amalgam removal protocol.

The risk of removing a filling without precautions

Here is the part many patients do not realize. Taking out an amalgam filling with no protection can expose you to more mercury vapor in a short window than the filling would have released sitting quietly in your mouth. That single fact is the reason the protective steps exist. If you decide to replace fillings, it is worth confirming that the dentist actually follows the protocol rather than drilling them out the conventional way.

Who should consider removal, and who might not

Removal is a personal decision, and it is not automatically right for everyone. Many biological dentists recommend leaving stable fillings that are not cracked, leaking, or causing symptoms exactly where they are, since every removal carries some procedural exposure. People move forward when a filling is failing, when they are planning a switch to biocompatible materials, or for a specific health goal they have discussed with their dentist. If you are pregnant or nursing, treat this as a careful conversation with a qualified professional before doing anything.

Questions to ask before you book

A short phone call tells you most of what you need to know. Ask whether the office uses a rubber dam, suction held at the tooth, supplemental air for you to breathe, room air filtration, and a charcoal or binder rinse before the procedure. Ask what material they will use to rebuild the tooth, and whether the dentist has completed IAOMT SMART certification. If the answers are vague, keep looking.

What it costs

Cost varies more than most dental work, because it depends on how many fillings you are replacing, the material used to rebuild each tooth, and where you live. The protective SMART steps can add to the price, and that added portion is often not covered by insurance even when the underlying filling replacement is.
