One of the most common questions we answer is whether metal fillings should be replaced. I have complied a list of 10 points about metal fillings and why I think they have had their day and alternative treatments should be sought:

1. Metal fillings contain up to 50% mercury.

2. Mercury is a toxin.

3. Mercury is continuously released from metal fillings via a vapour form.

4. Metal fillings do NOT stick to teeth, they are mechanically wedged in to place.

5. Metal fillings require the tooth to be cut deeper than white fillings as they rely upon an undercut in the tooth i.e wider base than top surface.

6. Metal fillings corrode over time leaving areas open to bacterial leakage.

7. Metal fillings cannot be repaired.

8. Metal fillings leach ions within the tooth to give a grey appearance.

9. Metal fillings cannot be placed next to gold crowns as this may lead to a galvanic effect and increase the corrosion rate.

10. Metal fillings look awful.

Modern replacements include composite resin fillings and porcelain inlay and onlay restorations. My next article will list points why these materials are superior than metal fillings.

A recent study by the European Commission has recommended phasing out the use of dental amalgam owing to mercury's negative impact on the environment. The study also stated that some dentists are ''reluctant to change their current practice and invest in new equipment to handle mercury free fillings''. 

At Progressive Dentistry, we do NOT use any mercury containing metal fillings. Dr Nissit Patel says '' I would not want a metal filling placed in my mouth or in my children so I will certainly not consider placing them for my patients. With modern dentistry and the development of adhesive dentistry, white tooth coloured restorations can be placed predictably and safely with fantastic aesthetic results.'' The options vary from direct composite fillings, to indirect porcelain fillings and crowns. We constantly invest in the latest technology and materials, to offer our patients the very best in dentistry today.
