What is SMART amalgam removal?

A precautionary approach used when an amalgam filling is being removed

The short answer: SMART amalgam removal is a protocol that uses additional precautions designed to reduce exposure to amalgam particles and mercury vapour while an amalgam restoration is being removed.

SMART stands for Safe Mercury Amalgam Removal Technique.

It was developed by the International Academy of Oral Medicine and Toxicology – IAOMT – and sets out a series of measures relating to isolation, suction, air management, water cooling, protective barriers and the way an amalgam restoration is removed.

There is one important distinction to understand from the outset:

SMART explains how an amalgam filling can be removed. It does not tell us whether the filling needs to be removed.

At Evolve Dentistry, that decision always comes first.

What is an amalgam filling?

Dental amalgam is a restorative material that has been used in dentistry for many years.

It is often described as a silver filling because of its appearance and is made from a mixture of metals, including mercury combined with metals such as silver, tin and copper.

Many adults have amalgam restorations that have been in their mouths for years.

Having one does not automatically mean anything needs to be done.

Like any dental restoration, an amalgam filling should be assessed as part of your routine dental care. If it remains serviceable and the surrounding tooth is healthy, continuing to monitor it may be appropriate.

If the restoration or tooth needs further treatment, removal may form part of that treatment.

Some adults may also ask about replacing a silver-coloured restoration because they would prefer a tooth-coloured alternative.

What does SMART stand for?

SMART stands for:

Safe Mercury Amalgam Removal Technique

The protocol was developed specifically for the removal of dental amalgam.

Removing an existing filling usually involves using dental instruments to separate the restoration from the tooth. During amalgam removal, this can produce particles, debris and vapour.

SMART brings together additional precautions designed to manage that treatment environment.

The full protocol is published by the IAOMT.

What happens during SMART amalgam removal?

The precise clinical setup depends on the tooth and individual treatment plan, but SMART includes measures relating to several areas.

Isolation of the treatment area

A rubber dam can be placed around the tooth being treated.

This creates a barrier between the treatment area and the rest of the mouth and helps control debris during the procedure.

If you have never experienced a rubber dam before, it can initially feel unusual. You remain able to breathe normally through your nose and communicate with the dental team.

High-volume suction

High-volume suction is positioned close to the treatment area.

This helps collect water, debris and material generated during removal.

Water cooling

Water is used while the restoration is being removed.

Among other purposes, this helps control heat generated during the use of dental instruments.

Sectioning the amalgam

Where clinically appropriate, the amalgam restoration can be divided into sections.

This allows pieces of the restoration to be removed rather than unnecessarily grinding away the entire filling.

Protective measures

SMART also includes additional protective measures for the patient and dental team and measures relating to air management in the treatment room.

Does SMART eliminate exposure completely?

No clinical protocol should be described as guaranteeing zero exposure.

SMART uses additional precautions designed to reduce exposure to particles and vapour during amalgam removal.

We deliberately avoid describing the technique as completely risk-free or claiming that it eliminates exposure altogether.

This is an important part of giving patients balanced information rather than overstating what a particular protocol can achieve.

Does using SMART mean amalgam fillings are dangerous?

No.

Using additional precautions during a removal procedure does not mean that every amalgam restoration needs to be removed.

These are two different questions:

Question one: Does this tooth or restoration need treatment?

Question two: If it is going to be removed, how will the removal be carried out?

SMART relates to the second question.

At Evolve, Carol or Maggie will first assess your existing restoration and the tooth around it.

If a filling is functioning appropriately, monitoring it may be a perfectly reasonable option.

Why might an amalgam filling be removed?

There are several possible reasons.

The filling requires replacement

Like any restoration, an amalgam filling may eventually require further treatment.

The surrounding tooth needs treatment

There may be a problem with the tooth itself that means the existing restoration needs to be removed.

A different restoration is needed

Depending on the amount of healthy tooth remaining, a tooth may require a different restorative approach.

Cosmetic preference

Some adults dislike seeing silver-coloured restorations and would prefer a tooth-coloured alternative.

That is something you can discuss with us, but removing a functioning restoration still involves further treatment of the tooth, so the advantages and disadvantages should be understood first.

SMART is not a reason for removal

This is perhaps the most important part of understanding SMART amalgam removal.

The existence of the protocol does not mean that amalgam fillings should routinely be removed.

At Evolve Dentistry, we do not recommend removing a sound amalgam restoration on the basis that doing so will improve your general health.

Instead, treatment decisions are based on the condition of your teeth and restorations, alongside your informed preferences.

If removal is appropriate and you choose to proceed, SMART can then form part of how that treatment is provided.

Myth vs reality

Myth: SMART means every amalgam filling should be removed

Reality: SMART is a removal protocol. It does not determine whether a restoration requires treatment.

Myth: SMART guarantees zero exposure during treatment

Reality: The protocol uses additional precautions designed to reduce exposure. It would not be appropriate to promise that exposure can be completely eliminated.

Myth: SMART is a type of filling

Reality: SMART describes the removal process. The tooth still needs to be restored afterwards using an appropriate restorative material.

Myth: Choosing SMART means you believe your filling is harming your health

Reality: Patients may require amalgam removal for ordinary restorative dental reasons or may choose replacement for aesthetic reasons. SMART relates to the procedure itself.

Who provides SMART amalgam removal at Evolve?

SMART amalgam removal for adult patients at Evolve Dentistry can be carried out by Carol Somerville Roberts or Maggie Nichols.

Your first appointment is about understanding the current condition of your teeth and your reasons for considering treatment.

If removal is appropriate, Carol or Maggie can explain:

  • the SMART precautions
  • what will happen during treatment
  • what restoration may be needed afterwards
  • likely appointment planning
  • potential risks and limitations
  • alternatives to treatment where appropriate

Frequently asked questions

Is SMART the same as ordinary amalgam removal?

The underlying dental objective is still to remove the existing restoration and restore the tooth appropriately. SMART adds a structured series of additional precautions specifically relating to amalgam removal.

Is a rubber dam always used?

Rubber dam isolation forms part of the SMART approach. Carol or Maggie can explain the exact clinical setup planned for your individual treatment.

Can SMART be used for several fillings?

Potentially. If several restorations require treatment, we will first assess each tooth and decide whether treatment is best provided together or divided between appointments.

Is SMART the same as mercury detoxification?

No. SMART relates to the dental procedure used to remove an amalgam restoration. At Evolve we do not position amalgam removal as a treatment for general medical symptoms or as a form of detoxification.

Does Evolve remove amalgam for cosmetic reasons?

Some adults ask about replacing visible silver-coloured restorations with tooth-coloured alternatives. We can assess whether this is clinically appropriate and discuss the implications before you decide.

Why is my dentist taking photographs of my teeth?

“Why are you taking photographs of my teeth?”

A perfectly reasonable question.

Dental photographs aren't just for before-and-afters.

They can help us record what we're seeing, monitor changes, explain things more clearly and involve you in conversations about your own teeth.

Richard explains why you might see a camera appear during an appointment at Evolve.

Because when we're talking about your mouth, we think it's rather useful if you can see what we're talking about too.
There's more to a smile transformation than two photographs

A before-and-after shows you two moments.

What it doesn't show is everything that happened between them.

The conversations. The planning. What the patient wanted to change. The different options considered. And the decisions about what not to change.

That's why we think the story behind a smile is every bit as interesting as the finished result.

Every patient is different - and every treatment plan should be too.

Here's one of the lovely transformations we've had the privilege of being part of at Evolve. 💚
What actually happens during a dental examination?

If it’s been a while since your last dental examination, not knowing what to expect can sometimes make booking that appointment feel like a much bigger deal.

So what actually happens when you come in?

Richard explains what your dentist is looking for during a dental examination - and why it involves much more than simply checking whether you need a filling.

Regular examinations give us an opportunity to keep an eye on your teeth, gums and mouth, talk about anything that has changed and identify anything that may need our attention.

And if you haven’t been for a while? Please don’t feel embarrassed.

We’re simply pleased you’ve decided to come and see us.
