Why Everyone Is Suddenly Talking About Silver Fillings
On July 22, 2026, federal health officials sent letters to Medicaid directors in all 50 states, encouraging them to stop covering dental fillings containing mercury. The headlines landed hard. If you have silver fillings in your own mouth, you may have read one and felt your stomach drop.
Dr. Carla Yamashiro has practiced mercury-free dentistry in Bonney Lake for 23 years. In her experience, roughly 70 percent of new patients arrive because of dental anxiety or a previous bad experience somewhere else. She has watched enough headlines frighten enough good people to know what happens next. Someone reads a news story, assumes the worst about a choice made years ago, and carries the worry alone for months.
This article walks through what the announcement says, what it leaves out, and how to think about your own fillings without panic. You are the one making the decision here. Our role is to hand you accurate information and then get out of your way.
What Did Federal Officials Actually Announce About Mercury Fillings?
The Centers for Medicare and Medicaid Services sent notifications on July 22, 2026 to every state Medicaid director, urging them to restrict or end coverage for dental amalgam procedure codes. No federal mandate was issued. Each state decides on its own whether to act, and on its own timeline.
The distinction matters more than the headlines suggest. Nothing about your existing fillings changed on July 22. What shifted is the direction federal health policy points, and it points toward mercury-free materials.
Two longer timelines sit behind the announcement. The Indian Health Service decided in February to end amalgam use in its facilities by 2027. The United States also belongs to the Minamata Convention on Mercury, where member countries committed in November 2025 to phase out dental amalgam by 2034.
Are Silver Fillings and Mercury Fillings the Same Thing?
Yes. A silver filling is dental amalgam, a mixture combining mercury with silver, tin, and copper. Mercury makes up roughly half of the material by weight. The word silver describes the color, not the main ingredient, which explains why one filling goes by two very different-sounding names.
Most people learn this in their forties and feel a little blindsided. The surprise is not a failure of attention on your part. The naming convention has been in place for more than a century, and nobody sat you down to explain the chemistry. Ask any question you want about the materials already in your mouth. We will answer plainly.
Does This Mean My Fillings Are Dangerous?
No dentist can answer this from a distance, and this article will not pretend otherwise. The American Dental Association continues to hold amalgam fillings as safe. The FDA takes a more cautious view, noting limited long-term outcome data in young children and advising extra care for populations including children under six.
Both positions come from serious people reading real evidence. We practice mercury-free at Ecologic because we weigh the same evidence and land somewhere more conservative, particularly for children, for anyone pregnant or planning a pregnancy, and for patients already carrying a heavy toxic load.
This is a difference in clinical judgment. It is not a claim your previous dentist did something wrong. Materials standards move over decades, and yours were placed under the standard of their time. We are glad you are here now.
Should I Have My Amalgam Fillings Removed?
The honest answer is your fillings, your timeline, your decision. Some patients remove amalgam because a filling has already fractured or started leaking. Others remove it as part of reducing overall toxic load. Plenty of people leave stable fillings alone for years. All three choices are legitimate, and individual results vary in every case.
Before you agree to removal anywhere, ask a few questions. The answers tell you how seriously a practice takes your safety during the procedure itself.
- What protocol do you follow when removing amalgam, and what does it involve
- Will I have a separate source of clean air to breathe during the appointment
- Do you use a rubber dam, and where is the suction positioned
- What happens to the removed material after it leaves my mouth
- Do you recommend removing every filling at once, or working in sections
- What would make you tell me to wait
A practice worth your trust answers each one without defensiveness. Watch closely for the last question. Anyone who never advises waiting is selling, not treating.
How Does Safe Mercury Amalgam Removal Technique Work?
SMART stands for Safe Mercury Amalgam Removal Technique. Drilling into amalgam releases mercury vapor for a few minutes, and the entire protocol exists to capture the vapor rather than let you breathe it. Being a mercury-free office describes what we do not place. It says nothing about how carefully we remove what is already there.
Here is what the protocol looks like in the operatory during your appointment.
- A rubber dam isolating the tooth from the rest of your mouth
- A separate source of clean air for you to breathe throughout
- High volume suction positioned directly at the tooth
- Protective coverings for your skin, eyes, and clothing
- An amalgam separator capturing material before it reaches wastewater
- Air filtration running in the room for the full appointment
Dr. Yamashiro holds the IABDM Integrative Biologic Dental Medicine Certificate, reflecting formal training in biological dental medicine rather than a marketing phrase. Every step above happens whether you ask about it or not.
How Do Local Practices Differ on Amalgam Removal?
Not every Bonney Lake or Pierce County office approaches removal the same way, and the differences are invisible from the waiting room. The table below shows what separates a standard approach from a protocol-driven one.
| Practice Factor | Standard Approach | Ecologic Dentistry |
| Air supply during removal | Room air only | Separate clean air source |
| Tooth isolation | Cotton rolls | Rubber dam |
| Room air handling | No filtration | Filtration for full appointment |
| Material capture | Standard suction | High volume suction plus amalgam separator |
| Pacing of treatment | Full mouth in one visit | Sectioned by your tolerance and health history |
| Consent conversation | Paperwork at check-in | Full walkthrough before scheduling |
These differences take place in minutes and follow you for decades. Ask about them anywhere you go, including here.
Whole-Body Care in Bonney Lake and Across Western Washington
Dr. Yamashiro trained in Integrative Biologic Dental Medicine and Naturopathic Medicine, and she practices with the whole person in view rather than one tooth at a time. Patients travel to Ecologic Dentistry from Lake Tapps, South Hill, Sumner, Puyallup, and Tehaleh. Others drive in from the Olympic Peninsula, from north of Seattle, and from Olympia and Lacey. One patient makes the trip from Oregon. Nobody drives that far for convenience. They drive for someone who explains things.
Holistic and biological care often falls outside insurance networks, and we tell you every number before anything begins. We think about cost as an investment in what your body no longer has to process over the coming decades.

Frequently Asked Questions
How do I know if my fillings contain mercury?
Any filling with a metallic silver-gray appearance is almost certainly dental amalgam, while composite fillings are tooth-colored and blend with enamel. The FDA’s guidance on dental amalgam describes the material composition and the populations it advises extra caution for. During an exam we can identify every filling in your mouth and tell you what each one is made of, then leave the decision entirely with you.
Is it safe to remove amalgam fillings during pregnancy?
We do not perform elective amalgam removal during pregnancy or while nursing, because waiting is the more protective choice for both of you. The FDA identifies pregnant women and their developing fetuses among groups warranting extra caution around mercury exposure. Come in, ask your questions, and let us map out timing alongside your obstetric provider so nothing happens sooner than it should.
Does the American Dental Association recommend removing amalgam fillings?
No, and you deserve to hear that from us rather than discover it later. The American Dental Association holds amalgam as a safe restorative material and does not recommend removing intact fillings. We reach a more conservative conclusion from the same evidence, particularly for children and pregnancy, and we would rather hand you both views than pretend a genuine professional disagreement does not exist.
What did the federal announcement actually say?
It encouraged, and did not require. You can read the full statement in the HHS announcement from July 22, 2026, which describes notifications sent to every state Medicaid director urging them to restrict or end coverage for dental amalgam. Each state decides whether to act and when. Your existing fillings are unaffected, and no deadline applies to you personally.
