Mercury Amalgam Filling Removal: The Complete UK Guide to Doing It Safely If you're considering having your old silver fillings removed, there is one thing that matters more than anything else: how they come out. Amalgam fillings are roughly half mercury, and the act of drilling one out releases a burst of mercury vapour. Removed properly, under a strict safety protocol, that exposure is minimised. So the question isn't only whether to remove them. It's who you trust to do it, and how. I'm Dr Daniel Sutcliffe. I've practised biological dentistry for over twenty years, I'm accredited by the IAOMT, and I'm currently the only IAOMT SMART Protocol Mentor in the United Kingdom. This guide is the honest version: what the evidence shows, what it doesn't, and how safe removal actually works. Do amalgam fillings really contain mercury? Yes. A traditional "silver" amalgam filling is an alloy of several metals, and mercury makes up around 50% of it by weight. The mercury binds the other metals, silver, tin, copper, into a hard, durable filling. That durability is why amalgam was used for well over a century. But the mercury never entirely stops being mercury, and small amounts of vapour are released over the life of the filling, rising when you chew, grind, or drink something hot. Are amalgam fillings safe? Here I'll give you the balanced picture, because you deserve it rather than a scare. Major health regulators, including the UK's MHRA, the US FDA and the World Health Organisation, consider amalgam safe for the general population. That is the mainstream position, and it's honest to state it plainly. At the same time, the picture has been shifting. In 2020 the FDA advised that certain groups should avoid amalgam where possible, including pregnant and breastfeeding women, children under six, people with kidney impairment, and anyone with a known sensitivity to mercury. And across the European Union, dental amalgam has been largely phased out from January 2025, driven chiefly by environmental concern about mercury pollution rather than a proven danger to patients. So the fair summary is this: for most people, regulators regard existing amalgam fillings as safe to leave in place, and the wider move away from amalgam is as much about the environment as about health. Why do people choose to have amalgam removed? People come to me for amalgam removal for a range of honest reasons: they dislike the look of dark metal in their smile, they want to move to tooth-coloured composite, an old filling is cracked or leaking and needs replacing anyway, they fall into one of the groups regulators suggest should avoid mercury, or they simply feel more comfortable, as a personal choice, not having mercury in their mouth. All of those are valid reasons to choose removal. What I'm careful never to promise is that taking your fillings out will treat or cure a medical condition. Will removing amalgam improve my health? This is the question I'm asked most, and it's where honesty matters most. There is no good evidence that removing amalgam fillings treats systemic illness, and I won't claim otherwise. If a practitioner promises that pulling out your fillings will fix fatigue, or a chronic condition, or anything similar, be cautious, because the science doesn't stand behind that promise. What I can say is that if you've decided to have amalgam removed, for any of the sound reasons above, then it should be done in the safest way possible. That's the part where the evidence is clear, and it's the part that actually protects you. The part that really matters: safe removal Here is the genuine, well-established risk, and it isn't the filling sitting quietly in your tooth. It's the removal itself. Drilling into amalgam generates heat and fine particles, and that produces a sharp, temporary spike in mercury vapour, far higher than the low background level from an intact filling. If that's done with no protection, you inhale it, the dentist inhales it, and the nurse inhales it. This is not controversial. It's precisely why a dedicated safety protocol exists. Done properly, that spike is captured and cleared before it reaches your lungs. Done carelessly, the removal can expose you to more mercury than leaving the filling alone ever would. That single fact is the whole reason safe technique matters. What is the SMART protocol? SMART stands for Safe Mercury Amalgam Removal Technique. It was developed by the IAOMT, the International Academy of Oral Medicine and Toxicology, and it's a set of measures designed to minimise mercury exposure during removal. In practice it includes: A rubber dam sealed around the tooth, so debris and vapour don't reach the rest of your mouth. Copious water and cooling to keep the filling from overheating and off-gassing. High-volume suction right at the tooth, plus a separate external suction unit beside your mouth to draw vapour away from your face. A supply of clean air for you to breathe throughout, so you're not inhaling from the working field. And full protective barriers, gowns, and respiratory protection for the whole team. Where possible, the filling is sectioned into chunks and lifted out, rather than drilled away entirely, which keeps vapour down. None of this is dramatic to sit through. It simply means the exposure that careless removal would create is contained and cleared. Who should remove your amalgam fillings? Any dentist can drill out a filling. Far fewer are trained and accredited to do it under a recognised safety protocol. If you're going to have amalgam removed, look for someone with genuine IAOMT accreditation and SMART training, not just a website that uses the words. Ask whether they use rubber dam isolation, external suction, and a supplemental air supply. A practitioner who does this properly will be glad you asked. For context on my own background: I qualified in 2004, I've focused on biological and integrative dentistry for over twenty years, I'm IAOMT accredited, and I'm the only IAOMT SMART Protocol Mentor in the UK, which means I train other dentists in safe removal as well as carrying it out for my own patients. What does safe amalgam removal cost, and what should I expect? At The Bespoke Dentist on Harley Street, the journey begins with a Signature Oral Health Assessment from £169, where we examine your fillings, discuss your reasons, and plan any removal properly around your particular mouth. From there, the cost of removal itself depends on how many fillings you have and what replaces them, and you'll have a clear plan before anything begins. A single visit is often enough for a few fillings; larger cases are staged sensibly over more than one appointment. You should expect the appointment to feel calm and unhurried, the protective set-up explained as we go, and tooth-coloured composite placed where the old metal was. Frequently Asked Questions Is amalgam filling removal safe? Removal is safe when it's carried out under a recognised protocol such as SMART, which uses rubber dam isolation, high-volume and external suction, cooling water, and a clean air supply to minimise mercury vapour. Removal without these precautions can expose you to more mercury than leaving the filling in place, which is why who performs it, and how, matters more than anything else.
