Mercury-Free & Tooth Colored Fillings
A tooth color composite resin blends in well with natural enamel.
A bonded tooth color composite resin, which is similar to enamel, that is bonded to the tooth surface to repair (fill) and/or change the color or shape of a tooth, the sculpted into shape, hardened, and polished. When teeth are chipped or slightly decayed, bonded composite resins may be the material of choice. Bonding also makes a great tooth colored filling for small cavities and broken or chipped surfaces.
Mercury is known to be one of the most dangerous and toxic substances on the planet. Many people are unaware that “silver” amalgam dental fillings are actually 50% mercury.
It has been proven that fillings lose their mercury content. According to Joyal Taylor, DDS, one dental researcher removed fillings that had been in a patient’s mouth for five years. He also removed twenty year old fillings from another patient’s mouth. He tested the percentage of mercury content if both fillings, and found that the five year old fillings had lost one half of their mercury, and the twenty year old fillings had lost all of their mercury. Fillings tend to fracture at the edges and begin to crumble away, and mercury is absorbed by the roots of the teeth as well as the surrounding bone and adjacent gum tissue.
Every day, we do things that can increase the release of mercury vapor from amalgam fillings: brush our teeth, use a water pick, chew gum, and consume hot foods and drinks. And removing amalgams without special precautions increases mercury blood levels for a period of time. Such a concentrated release of mercury can severely exacerbate existing neurological conditions.
To Remove or Not to Remove: Is There a Question?
You may be wondering if you should have all of your amalgam fillings replaced immediately. The answer is, that it totally depends upon your situation. It is important to realize that for every person who has their amalgams removed and gets great results, such as lessened fatigue or neurological symptoms, there is another person who sees no change or actually becomes worse.
The type of dental materials that will replace your old amalgam fillings include etchings, composites, bonding agents, crowns, porcelain and ceramics, temporary materials, cements, adhesives, and sealants, to mention a few.
- Dental Amalgam contains about 50% Mercury.
- Mercury has been scientifically demonstrated to be more toxic than Lead, Cadmium or even Arsenic.
- Mercury leaves dental amalgam continuously throughout the lifetime of the filling.
- Mercury vapour is the main way that mercury comes out of amalgam.
- Mercury vapour is absorbed at a rate of 80% through the lungs into the arterial blood
- Mercury kills cells.
- There is NO harmless level of Mercury Vapour Exposure
- Mercury from mercury fillings binds to sulphydryl groups. These exist in almost every enzymatic process in the body. Mercury from amalgam has the potential to disturb all metabolic processes
- Mercury from amalgam is transported freely via the blood
- Mercury vapour is absorbed directly into the brain
- Mercury from amalgam will result in a slow build up of mercury in body tissues
- Mercury crosses the blood brain barrier
- Mercury is implicated in Alzheimer's Disease
- Mercury from amalgam is stored in the fetus and infant before the mother (Could this be part of the reason for children getting cancer?).
- Mercury from amalgam is stored in the breast milk and the fetus up to 8 times more than the mother's tissues
- Mercury crosses the placenta
- Mercury crosses into breast milk
- Mercury will severely reduce reproductive function
- Mercury rapidly depletes the immune system
- Mercury will induce a number of Auto Immune Diseases
- Mercury will cause an increase in number and severity of all allergies
- Mercury from amalgam is stored principally in the kidneys, liver and brain
- Mercury from amalgam causes kidney damage (shown in animal experiments)
- Mercury from amalgam causes a 50% reduction in Kidney filtration, as shown in a study of sheep after amalgam placement
- After chewing, Mercury vapour levels will remain raised for at least another 90 minutes
- Mercury from amalgam will migrate through the tooth
- This rate of migration is increased if a gold crown is placed over a tooth filled with amalgam
- Teeth are living tissues and are a part of our bodies
- Teeth have a massive communication via blood, lymph and nerves with the rest of the body
- Mercury from amalgam is absorbed into the body at a rate of 3 to 17 mcg / day (WHO 1991 Criteria)
- Mercury is transported along nerve fibers
- Mercury form amalgam may be stored in every cell in the body. Each area affected will produce its own set of symptoms
- Mercury binds to haemoglobin in the red blood cell thus reducing oxygen carrying capacity
- Mercury damages blood vessels, thereby reducing blood supply to the tissues
- Amalgam fillings produce electrical currents which are no doubt injurious to health. These currents are measurable in Micro Amps. The Central Nervous System and Brain operate in the range of Nano-Amps, which are 1,000 times less than a Micro Amp
- Dissimilar metals in the mouth, such as gold and amalgam, produce higher electrical currents
- Brain levels of mercury are in a direct linear proportion to the number of surfaces of amalgam fillings in the mouth
- Mercury will cause single strand breaks in DNA
- Mercury levels in the blood can NOT be assessed by blood or urine levels
- Dental personnel are severely affected by exposure to mercury
Mercury teeth fillings may harm some: FDA
By Susan Heavey
WASHINGTON (Reuters) - Silver-colored metal dental fillings contain mercury that may cause health problems in pregnant women, children and fetuses, the Food and Drug Administration said on Wednesday after settling a related lawsuit.
As part of the settlement with several consumer advocacy groups, the FDA agreed to alert consumers about the potential risks on its website and to issue a more specific rule next year for fillings that contain mercury, FDA spokeswoman Peper Long said.
Millions of Americans have the fillings, or amalgams, to patch cavities in their teeth.
"Dental amalgams contain mercury, which may have neurotoxic effects on the nervous systems of developing children and fetuses," the FDA said in a notice on its Web site.
"Pregnant women and persons who may have a health condition that makes them more sensitive to mercury exposure, including individuals with existing high levels of mercury bioburden, should not avoid seeking dental care, but should discuss options with their health practitioner," the agency said.
The FDA said it did not recommend that people who currently have mercury fillings get them removed.
The FDA must issue the new rules in July 2009, Long said.
Such a rule could impact makers of metal fillings, which include Dentsply International Inc and Danaher Corp unit Kerr.
The new rule will give the agency "special controls (that) can provide reasonable assurance of the safety and effectiveness of the product," Long said.
The lawsuit settlement was reached on Monday with several advocacy groups, including Moms Against Mercury, which had sought to have mercury fillings removed from the U.S. market.
While the FDA previously said various studies showed no harm from mercury fillings, some consumer groups contend the fillings can trigger a range of health problems such as multiple sclerosis and Alzheimer's disease. In 2006, an FDA advisory panel of outside experts said most people would not be harmed by them, but said the agency needed more information.
Mercury has been linked to brain and kidney damage at certain levels. Amalgams contain half mercury and half a combination of other metals.
Charles Brown, a lawyer for one of the groups called Consumers for Dental Choice, said the agency's move represented an about-face. "Gone, gone, gone are all of FDA's claims that no science exists that amalgam is unsafe," he said in a statement.
J.P. Morgan Securities Inc. analyst Ipsita Smolinski said the FDA is not likely to outright ban the fillings next year but will probably call for restrictions.
"We do believe that the agency will ask for the label to indicate that mercury is an ingredient in the filling, and that special populations should be exempt from such fillings, such as: nursing women, pregnant women, young children, and immunocompromised individuals," Smolinski wrote in a research note on Wednesday.
Fewer patients have been opting for mercury fillings in recent years, instead choosing lighter options such as tooth-colored resin composites.
Only 30 percent of fillings given to patients were mercury-filled ones as of 2003, according to the American Dental Association (ADA). Other options include glass cement and porcelain as well as other metals such as gold, but they cost more and are less durable, the group has said.
