• Mercury Removal Dentistry

  • For more than 100 years, dental amalgam has been used widely throughout the world as a filling for damaged teeth. The composite material is composed of a mixture of silver, tin, copper and liquid mercury. The liquid mercury is about 40-50 percent of the mixture.

Dental amalgam is very strong and durable. Amalgam is also not affected by moisture when being applied to the tooth, so bonding is easier. Once the bond is made, amalgam fills the tooth imperfections and becomes very resistant to bacteria.

    From a pure esthetic perspective, amalgam fillings do not match the color of natural teeth. The amalgam is silver and often changes to black over time. When applying amalgam, some of the tooth needs to be sacrificed to allow the amalgam to adhere. Once the amalgam is in place, some expansion occurs over time and can cause further amounts of tooth loss.

    Other disadvantages of dental amalgams include the slow set time – patients are advised not to chew foods for a set amount of time. Mercury based fillings are good conductors of heat and cold, meaning sensitivity to temperatures is very common and can cause nerve pain, forcing some patients to avoid certain foods.

    Finally, the permanent presence of mercury and other elemental metals raises concerns about toxicity and allergies. Even in the 1800s when dental amalgams were introduced, there was concern about placing toxic materials into the mouth. Mercury vapor is released during the application process and during normal chewing, which is a concern for some people.

    When you have dental amalgams removed, the dentist will take many precautions to reduce or eliminate the amount of mercury vapors released. The use of high suction and lots of water, along with removing as much material at one time are some of the ways to reduce mercury vapors. Once the fillings are removed, the tooth-colored resin is applied and the appearance the structure of the tooth will be much more satisfactory.
