    It consists of mercury (approximately 50%) and differing amounts of other metals such as silver (mostly 30%), zinc, tin and copper. This type of filling last for 5 to 10 years (expected) but some filings may last even up to twenty years. It is the cheapest of all but it takes some time to get inserted.

  • Galloy:

    This type is the brand new dental filling material which consists of silver, copper, tin, indium and gallium. It is meant to be with mercury-free and an alternative to the amalgam fillings.

  • Direct composite:

    It is the most popular inlay dental fillings which is made of a special plastic material which bonds chemically to the tooth structure. This type of dental filling material lasts for 5-7 years, but the smaller filings with direct composite last much longer than other materials. This types of dental fillings cost more and takes more longer time to insert than amalgam, but its advantages makes it worthy.

  • Indirect composite onlay/inlay filling:

    This type of filling material is used when an idea anatomy, durability and fit is desired, that is achieved seldom with the direct composite filling. It costs 2 to 3 times more than the amalgam and takes about 2 visits to set in.

  • Gold onlay/inlay:

    This type of dental filling is used only when maximum strength is a concern and desired and when the appearance is not at all a concern. It cost 3 to 4 times more than the amalgam and takes 2 visits to set it.

  • Titanium onlay/inlay:

    This type is used when the gold filling is not possible. It cost, time for insertion and perform and benefits are as same as gold filling. Inspite of the fact that the metal is not so precious.
