The most common Dental Fillings used nowadays in treating cavities are Dental Amalgam. Gold was used by Ancient physicians, and they made the better choice.
Dental fillings are usually made from porcelain or dental amalgam. Porcelain has the advantage of having the same color as other teeth. But it is basically glass, so it is less durable than amalgam and it’s more expensive. Porcelain and other dental composites need a “special care” compared to amalgam and metal fillings. It is widely common to have dental amalgam fillings in treating crowns and making permanent bridges.
It is mostly common to have porcelain fillings for the front teeth, to have a natural appearance. But, what about the back teeth that can’t be seen in our daily life? And what about those who think more pragmatically and doesn’t concern themselves with looks? There are 2 options here; the first is having a dental amalgam filling. The second option is to have a gold tooth.
Usually, dental amalgam is 50% mercury, 22.3% silver, 14% tin, 8% copper and other metals. The problem it poses is the high percentage of toxic mercury released by amalgam fillings. This mercury is proven to leak by 1 microgram/day to 27 microgram/day increasing the level of mercury in the blood stream. It is arguable how this dose effect the health of the patient, but mercury is something we don’t want running through our veins especially pregnant and breastfeeding mothers.
Gold dental fillings are a whole different story. To start, gold has been used in making teeth replacements since the ancient shamans. Its malleability and immunity to corrosion in air and water made it the best choice for ancient physicians. It is the most noble of noble metals, and it resists attacks by acids which cause dental corrosion and cavities. Plus, few people are allergic to gold. The only disadvantage of gold is its appearance, which is controversial and depends on individual detentions of beauty.
On the other hand, gold greatest advantage is longevity, along with being the most bio-compatible element ever used. Gold can withstand daily pressure 3 times longer than any other dental filling. As for costs, it’s arguable that gold fillings are cheaper than porcelain on the long run. Who advocates gold fillings talk about decades of service against porcelain and amalgam years of service. You might know someone who has a 50 years old gold tooth with no problems yourself.
So, unless the patient is obsessed by looks, gold teeth are the best choice, economic wise and health wise. Remember to ask your dentist for recommendations and bear in mind the physical properties and the toxicity of each material used. Don’t forget to do same math and check for cost over time, and decide which better suits you.
