Amalgam Fillings Removal: Everything You Need to Know

Medically reviewed content. Written with guidance from licensed dental practitioners.

Amalgam fillings removal has become a more common conversation in dental offices over the past few years — not because amalgam suddenly became unsafe, but because regulatory guidance has shifted, and more patients are asking questions their dentist may not have been asked a decade ago. This guide covers what amalgam actually is, why people choose removal, what the current regulatory and scientific picture actually says, what the removal process involves, and what it costs in 2026.

What Are Amalgam Fillings?

Amalgam fillings are a mixture of metals — mercury, silver, tin, and copper — with mercury making up approximately 50% of the composition by weight. They’ve been used in dentistry for well over 150 years and remain valued for durability and strength, particularly on posterior (back) teeth that endure heavy chewing pressure.

Advantages of Amalgam Fillings

Durability — amalgam fillings can last 10 to 15 years or longer
Cost-effectiveness — generally less expensive than composite, ceramic, or gold alternatives
Strength — highly resistant to wear under heavy chewing forces

Disadvantages of Amalgam Fillings

Aesthetics — the silver color doesn’t match natural tooth shade
Mercury content — an ongoing subject of regulatory review, particularly for specific higher-risk groups (detailed below)
Expansion and contraction — amalgam responds to temperature changes over time, which can occasionally contribute to tooth fractures in older fillings

The Current Regulatory Picture: What the FDA and ADA Actually Say

This is the part of the amalgam fillings removal conversation that has changed the most in recent years, and it’s worth understanding both sides clearly rather than picking one.

In September 2020, the FDA updated its guidance and recommended that certain higher-risk groups avoid new dental amalgam when possible and appropriate. The FDA’s own patient-facing guidance names these groups explicitly:

Pregnant women, and women planning to become pregnant
Nursing mothers and their newborns
Children, particularly those under six
People with pre-existing neurological disease, such as multiple sclerosis, Alzheimer’s, or Parkinson’s disease

People with impaired kidney function
People with a known allergy or heightened sensitivity to mercury or amalgam components

Importantly, the FDA’s updated guidance applies to new amalgam placement in these groups — it explicitly does not recommend removing or replacing existing amalgam fillings that are intact and in good condition, since the removal process itself temporarily increases mercury vapor exposure and removes healthy tooth structure along with the filling.

The American Dental Association’s position, following that same 2020 update, was to reaffirm amalgam as a durable, safe, and effective option for the general population, noting that no new scientific evidence had been cited as part of the FDA’s recommendation — a genuine disagreement in emphasis between the two organizations that patients are often not told about.

What to look for: if you fall into one of the FDA’s identified higher-risk groups and are getting a new cavity filled, that’s the clearest, most evidence-aligned reason to ask for a non-mercury alternative. If you have existing, intact amalgam fillings and don’t fall into a higher-risk group, the evidence for removal is considerably less clear-cut, and it’s worth having that specific conversation with your dentist rather than assuming removal is automatically the safer choice.

International Context: The EU Amalgam Phase-Out

Regulatory movement isn’t limited to the U.S. Under European Union rules, dental amalgam was already restricted for children under 15, pregnant or breastfeeding women, except when a dentist judges it strictly necessary for the specific patient. As of January 1, 2025, the EU prohibited the manufacture and export of dental amalgam, and further restrictions on import and manufacturing take effect in mid-2026 — effectively phasing amalgam out of the EU dental market on environmental and precautionary grounds, distinct from the FDA’s narrower, risk-group-specific guidance in the U.S.

This distinction matters: the EU’s phase-out is driven substantially by environmental mercury policy, not solely by a finding of harm to patients, while the FDA’s guidance is specifically about certain patient subgroups. Conflating the two often overstates what either body has actually concluded.

Reasons for Amalgam Fillings Removal

Health Concerns

Some patients want amalgam removed due to concerns about cumulative mercury exposure, particularly if they have multiple fillings or a condition that falls into one of the FDA’s identified higher-risk categories. It’s worth noting that research on patients who’ve had amalgam removed shows a measurable decrease in urine mercury levels, but not a meaningful decrease in blood mercury levels even years afterward — an important nuance if health improvement is the primary motivation, since it suggests removal’s effect on total body mercury burden is more limited than many patients expect.

Aesthetic Preferences

Many patients simply prefer a tooth-colored restoration, especially for fillings visible when they smile or speak.

Underlying Tooth Decay

If decay has developed beneath or around an amalgam filling, the filling typically needs to come out regardless of any mercury-related consideration, simply because the tooth underneath needs treatment.

Wear, Cracking, or Filling Failure

Amalgam fillings don’t last indefinitely. Over 10–15+ years, they can wear down, crack, or develop marginal gaps that require replacement on structural grounds alone.

The Amalgam Filling Removal Process

1. Consultation

Your dentist will discuss your specific reasons for wanting removal, review your medical history (particularly relevant if you fall into an FDA-identified higher-risk group), and walk through what to expect.

2. Preparation

Expect X-rays to assess the tooth and surrounding structure, followed by local anesthesia to numb the area before the procedure begins.

3. Removal Procedure

Isolation — a rubber dam isolates the tooth to prevent debris and mercury particles from entering the rest of the mouth
Drilling — the dentist carefully sections and removes the amalgam, which can generate heat and mercury vapor, making ventilation and suction essential
Debris management — high-volume suction minimizes exposure to mercury vapor and particulate debris

Assessment — once the filling is out, the dentist checks the tooth for decay or structural damage before proceeding to replacement

4. Replacement Filling Options

Composite resin — tooth-colored, shade-matched to surrounding teeth
Glass ionomer cement — tooth-colored and fluoride-releasing, bonds well to tooth structure
Porcelain or ceramic inlays/onlays — custom-fabricated restorations offering greater strength and aesthetics for larger repairs

Safety Considerations: The SMART Protocol

Many dentists who perform amalgam removal follow the Safe Mercury Amalgam Removal Technique (SMART), a protocol developed by the International Academy of Oral Medicine and Toxicology (IAOMT) — it’s worth noting IAOMT is an advocacy organization focused specifically on reducing mercury exposure in dentistry, distinct from the FDA or ADA, so its recommendations reflect that particular orientation. SMART protocol elements typically include:

Rubber dam isolation to prevent inhalation or ingestion of mercury particles
High-volume external suction to capture mercury vapor and debris
Air filtration to reduce ambient mercury vapor concentration in the treatment room

Supplemental clean air delivered via a nasal mask so the patient isn’t breathing treatment-area air
Protective gear for the dentist and staff, including masks and gloves

Not every general dentist is SMART-certified, so if this protocol matters to you, it’s worth confirming certification directly rather than assuming it’s standard practice.

What Amalgam Removal Costs in 2026

Cost varies substantially depending on whether a standard removal or a full SMART-protocol removal is performed, and whether the replacement material is composite, ceramic, or something requiring a crown.

Standard (non-SMART) removal and composite replacement: roughly $250–$800 per tooth for straightforward cases; more if decay has developed or the filling is large
SMART protocol removal: typically adds a dedicated safety fee on top of the restoration cost — commonly cited SMART-specific fees range from about $99 to $250 per tooth, though some practices bundle safety and restoration into an all-in fee of roughly $500–$1,000 per tooth

If a crown becomes necessary (in cases of larger decay or a structurally compromised tooth), total cost per tooth can run up to $2,000–$3,000

Insurance note: most dental plans cover filling replacement when it’s medically necessary (decay, damage, or failure), typically at 30–80% depending on your plan and annual maximum. Removal performed solely for mercury-related or cosmetic reasons — when the existing filling is otherwise intact — is often not covered, and SMART-specific safety fees in particular are frequently excluded from coverage regardless of the reason for removal. It’s worth confirming this distinction with your insurer before scheduling.

Post-Removal Care

Pain management — over-the-counter pain relievers typically manage any short-term sensitivity or discomfort well; sensitivity to hot, cold, or biting pressure for a few days after the procedure is normal and usually resolves on its own.

Dietary adjustments — avoid hard or sticky foods for a few days while the tooth and any new restoration settle, and favor the opposite side of the mouth for chewing initially if the area still feels tender.
Oral hygiene — maintain normal brushing and flossing to support healing and reduce infection risk; a soft-bristled brush around the treated tooth for the first few days can help if the gum tissue feels irritated.
When to call your dentist — persistent pain beyond a few days, a bite that feels noticeably uneven, or visible swelling are reasons to follow up rather than wait it out, since they can indicate the new restoration needs adjustment.

Deciding Whether Removal Is Right for You

Since the FDA and ADA don’t fully align on this topic, it can help to work through a short set of questions with your dentist rather than defaulting to either position:

Is the filling currently intact, or is there decay, cracking, or marginal breakdown? Structural problems are a straightforward case for replacement regardless of material concerns.
Do you fall into one of the FDA’s identified higher-risk groups — pregnant, nursing, under six, a relevant neurological condition, impaired kidney function, or a known sensitivity? This is the clearest evidence-based reason to prioritize non-mercury materials, particularly for any new filling.

Is your primary motivation cosmetic, health-related, or both? Cosmetic preference alone is a perfectly valid reason to replace an amalgam filling — it just changes what “success” looks like and what insurance is likely to cover.
Have you asked your prospective dentist directly whether they follow the SMART protocol, and if so, what the added cost is? Not all dentists do, and the answer affects both cost and process.

None of these questions has a universally right answer — they’re meant to clarify which of your specific reasons for considering removal actually apply to you, so the conversation with your dentist starts from your situation rather than a general debate about amalgam safety.

Frequently Asked Questions About Amalgam Fillings Removal:

Should I have my amalgam fillings removed if they’re intact and not causing problems?

Current FDA guidance does not recommend removing intact, well-functioning amalgam fillings, since the removal process itself temporarily increases mercury vapor exposure and removes healthy tooth structure. The FDA’s higher-risk guidance is specifically about avoiding new amalgam placement in certain groups, not about removing fillings that are already in place.

Does removing amalgam fillings lower mercury levels in the body?

Research shows urine mercury levels typically decrease after removal, but blood mercury levels often don’t show a meaningful decrease even years later, suggesting removal’s effect on overall body mercury burden is more limited than commonly assumed.

Who is considered higher-risk for amalgam exposure under current FDA guidance?

Pregnant women and those planning pregnancy, nursing mothers and their newborns, children (especially under six), people with pre-existing neurological disease, people with impaired kidney function, and people with a known mercury or amalgam sensitivity.

What is the SMART protocol, and is it necessary?

SMART (Safe Mercury Amalgam Removal Technique) is a set of precautions — rubber dam isolation, high-volume suction, air filtration, and supplemental clean air — designed to minimize mercury exposure during removal. It’s not universally required, but many patients specifically seek out SMART-certified dentists for amalgam removal.

How much does amalgam filling removal cost?

Standard removal with a composite replacement typically runs $250–$800 per tooth. Full SMART-protocol removal often adds a separate safety fee (commonly $99–$250) on top of the restoration cost, and cases requiring a crown can run $2,000–$3,000 per tooth.

Will insurance cover amalgam removal?

Usually only when removal is medically necessary — for decay, damage, or filling failure. Removal done solely for mercury-related or cosmetic reasons on an otherwise intact filling, and SMART-specific safety fees, are commonly excluded from coverage.

What will my amalgam filling be replaced with?

The most common alternatives are tooth-colored composite resin, fluoride-releasing glass ionomer cement, and, for larger restorations, custom porcelain or ceramic inlays and onlays.

Bottom Line

Amalgam fillings removal is a legitimate option for the right reasons — decay, damage, aesthetic preference, or membership in one of the FDA’s identified higher-risk groups facing a new filling — but current FDA guidance stops short of recommending removal of intact, well-functioning amalgam in the general population, and the ADA continues to affirm amalgam’s safety and durability overall. If you’re considering removal primarily for health reasons, it’s worth discussing your specific risk profile with your dentist, understanding that blood mercury levels often don’t drop meaningfully after removal, and confirming whether your dentist follows the SMART protocol and how that affects total cost before scheduling.

Amalgam fillings removal is a decision that should be made with careful consideration and consultation with a dental professional. While concerns about mercury exposure exist, the procedure can be performed safely when following established protocols.
