Mercury Free Fillings: Why Your Teeth Fillings Matter

But have you ever thought about what teeth filling might be best for you in the future? When it comes to fillings, dentists use a variety of different materials from gold, silver, resin composites, to amalgam. Amalgam consists of materials such as copper, zinc, silver, tin, and mercury. But today more dentists are using fillings that are mercury-free because of health concerns.


Which Teeth Fillings Are Best?

Different teeth fillings will have their own set of advantages and disadvantages. Gold fillings are durable but do not match the color of the teeth and need more dental visits. Silver fillings have great strength but can destruct the teeth, causing more cracks and fractures. Composite materials match the color of the teeth but can be easily chipped later on. Each person will have their preference, but these are mercury free, and that is important.

What type of teeth filling your dentist uses is important as far as comfort for yourself, durability of the material, cost of the material, and what your insurance can cover. But of the materials that dentists are able to use for teeth fillings, more and more are going mercury free.


Going Mercury Free

When mixed with other minerals such as copper, zinc, silver, and tin – mercury becomes an alloy. However, recently there has been concern that neurotoxins may greatly affect children, pregnant woman, and those with certain health conditions. Not only is it believed that it would it affect the patient, but it would affect the dentist or assistant(s) as well who are working with the mercury.  Thus because of health concerns, dentists are turning to other methods.

Not only could it possibly endanger a patient’s health, but compared to other tooth filling materials, mercury may not be the best choice of material to use. To be used, mercury takes a great deal of removal of the tooth to be placed inside and over time it could actually expand and contract over time to crack teeth and causing even more dental work.

For those who wish to go mercury free with their teeth fillings, there are other options as previously discussed though any material will have their advantages and disadvantages.  A popular alternative is resin composite. Overtime it can preserve healthy teeth including the structure, lasts longer, and needs less dental work. For those who do wish to go mercury free, many dentists offer these services for their patients.

    Amalgam is not a true alloy either, it is made up a mixture of “phases” of varying stability, therefore upon agitation it still releases merfury or allows it to corrode.

    Teeth filings with mercury are long gone, I wonder if there are anybody out there who will still patronage it.
