Dental amalgam, which consists of a mixture of mercury, silver, tin and copper, has been used to fill teeth for over 200 years.
Amalgam restorations can remain functional for many years without causing concern. However, many of these older restorations are now wearing out, and because they do not bond to teeth deterioration of the edges and tooth cracking are commonly seen. Apart from the question mark hanging over the issue of mercury usage in dentistry, dental amalgam as a material does not resemble tooth tissue in any way and could actually be considered unsightly nowadays.
Dental problems associated with amalgam fillings
The most common reasons for replacing amalgam restorations are structural rather than systemic.
Typical dental issues include:
• cracked or fractured fillings
• leakage at the edges of restorations
• secondary decay beneath a filling
• weakened tooth structure surrounding the amalgam
These problems are not uncommon in older restorations that have been in place for many years.
When deterioration occurs, replacement with modern restorative materials will help to restore the structural integrity of the tooth.
Mercury exposure and patient concerns
Amalgam contains elemental (liquid) mercury bound within a metal colloid. Small quantities of mercury vapour are released all the time, but particularly during chewing and tooth brushing. This is an irrefutable fact.
The only debate within the dental profession hinges upon whether the small amounts of mercury vapour constantly released are significant: it is a scientific fact that the vapour is emitted. However, increasing numbers of patients are concerned about long-term exposure, particularly in view of the fact that the material is now banned in many countries, including the EU bloc. It should also be noted that the World Health Organisation does not recognise any safe level of mercury exposure.
For this reason, many patients are choosing to have their mercury amalgam fillings replaced with modern mercury-free materials. However, where this is being considered, Jeff believes that it is important that removal is carried out using the SMART amalgam removal technique.
When patients choose to replace amalgam fillings
Patients may consider replacement of amalgam fillings for several reasons.
These may include:
• deterioration of older fillings
• cosmetic preference for tooth-coloured restorations
• desire to reduce mercury exposure
• structural weakness or cracking of the tooth
In many cases treatment can be carried out gradually over time, depending on the number of fillings involved and the overall condition of the teeth.
A balanced clinical approach
Decisions about replacing amalgam fillings should be made on an individual basis following detailed dental examination.
In some cases existing restorations remain stable and do not require immediate replacement. In other cases, particularly where fillings are cracked or leaking, replacement may be recommended in order to protect the underlying tooth structure.
A careful clinical assessment allows the most appropriate course of action to be discussed.
Safe replacement of mercury fillings
Where amalgam fillings are to be replaced, removal should always be planned and carried out carefully.
At The Clinic – Mercury Removal Centre in Brighton, amalgam restorations are always removed using the SMART protocol (Safe Mercury Amalgam Removal Technique). This careful approach incorporates protective isolation, controlled removal techniques and air management systems designed to eliminate mercury exposure during treatment.
You can read more about this procedure on our SMART amalgam removal page.
Consultation and Assessment
If you are concerned about older amalgam fillings or would like advice regarding possible replacement, a Consultation allows Jeff to assess the condition of existing restorations and discuss appropriate treatment options.
At The Clinic we take a careful and measured approach, focusing on long-term dental health and structural integrity of the teeth.

Frequently Asked Questions
Can mercury fillings cause symptoms?
For many people amalgam fillings do not produce noticeable symptoms, either dentally or systemically. However, older fillings may crack, leak or allow decay to develop beneath them, which can lead to dental problems requiring treatment. All emit mercury vapour.
Should all mercury fillings be removed?
This is of course elective. Many amalgam restorations remain stable as fillings for many years. Replacement is usually considered, however, where fillings have deteriorated or where patients prefer mercury-free materials.
Is SMART amalgam removal necessary?
When amalgam fillings are replaced, refined removal protocols such as SMART are designed to eliminate mercury exposure during the procedure. At The Clinic, this protocol is mandatory for our patients.
What replaces mercury fillings?
Modern, non-toxic restorations typically use tooth-coloured composite materials or ceramic restorations depending on the structural requirements of the tooth.
