Our Strong Ethos Against Mercury!

Here at Newnham Dental Practice we are sympathetic to patients who believe that their health problems may be attributable to mercury.  We take the time to listen and to explain the procedures we take to help them to minimise their mercury levels.

 

WHY MERCURY FREE?
We hear continuously that amalgam, containing mercury, has been used as a tooth restorative material for more than 150 years. This does not mean that its use should continue without question. It has now been scientifically proven beyond any doubt that mercury, in its vapour form, is released from the surface of amalgam fillings in response to chewing and consumption of hot liquids. The vapour passes through the skin in the mouth into the body.

Mercury has a very strong affinity to lipid or fatty tissue - the greatest organ accumulation of fatty tissue is the brain and nervous system This can have a disastrous knock on effect on the endocrine and immune systems. People have varied immune system responses and breakdown of the body's immune system often presents with varied symptoms. The presence of other heavy metals, notably lead, cadmium, aluminium and nickel, worsens immune depression.

It is most fortunate that the human body is as resilient as it is because most people with amalgam fillings do not exhibit any symptoms that they are aware of. However, in a 1997 publication the British Dental Association stated "about 3% of the population are estimated to suffer from mercury sensitivity" which means that 1.75 million people in this country are showing symptoms from mercury toxicity. Given that the BDA, are at best, sceptical about the effects of mercury on the population one might surmise that their estimate of 3% may be a small percentage but it is still a lot of people. Draw your own conclusions and do the maths with a population of approximately 60 million.

We at the practice do not wish to pressure patients into a rush to have all amalgam restorations removed but to point out that we feel that metal fillings are not the safe material they have been thought to be and all replacement fillings at Newnham Dental practice are done using white composite material.

Composite is a white filling material which comes in a variety of shades. It is a paste which is placed in the tooth and cured using a blue light to harden it. There are disadvantages to using composite and it has to be accepted that placement of the material is very technique sensitive. This does mean that composite fillings will take twice as long to complete than the amalgam and the result is that they cost more.
