Amalgam dental fillings have very small amounts of mercury. The amount of mercury that might leak out is not dangerous. It causes no harm, except for very rare allergic reactions. You get much more mercury from eating certain seafoods.

Approximately half of a dental amalgam filling is liquid mercury and the other half is a powdered alloy of silver, tin, and copper.
Mercury is used to bind the alloy particles together into a strong, durable, and solid filling. Mercury's unique properties it is a liquid at room temperature that bonds well with the alloy powder make it an important component of dental amalgam that contributes to its durability. There are several different chemical forms of mercury: elemental mercury, inorganic mercury, and methylmercury.
The form of mercury associated with dental amalgam is elemental mercury, which releases mercury vapor. The form of mercury found in fish is methylmercury, a type of organic mercury. Mercury vapor is mainly absorbed by the lungs.
Methylmercury is mainly absorbed through the digestive tract. But if the tooth has already experienced considerable decay, a traditional filling may be necessary. This makes it two times more resistant to fracture than standard composite fillings. The researchers also developed a dental adhesive a glue to hold the composite filling in that contains a polymer called methacrylamides.
Early research shows that methacrylamides are 30 percent stronger than current materials after 6 months of use. Methacrylamides may also be more resistant to bacteria and enzymes in the mouth. Combined, thiourethane and methacrylamides may have the potential to make your fillings last longer.
This is done by removing the inside of the tooth root and putting a special rubbery filler into the tooth to preserve it. A crown or veneers may also be appropriate.
