An amalgam filling is one of the oldest materials used to fill cavities in teeth caused by caries. Restorations with this material appeared at the end of the 17th century and were modified at the beginning of the 20th They had better properties, such as resistance to corrosion. A dental amalgam filling is a mixture of metals such as silver, copper, and tin. It is composed of approximately 60% liquid mercury. The presentation of modern amalgam, accepted by the American Dental Association, is in capsules that contain the exact proportion of metals to facilitate use since it reduces the dentist’s time by making it easier to mix, and an exact proportion is essential to maintain the properties of the material. Amalgam fillings have been a material of choice because of the low cost, easy application, and long- lasting, resistant properties.

Thanks to its different properties, amalgam fillings have been the most widely used dental material, especially in dental cavities in posterior and large teeth. However, to be able to use it, cavities must meet certain requirements to retain the material.
As mentioned,, amalgam filling restorations are characterized by high durability. If you have restorations with this material, as with others, it is advisable to make continuous visits to your dentist to check the condition of the restorations. If your dentist deems the restorations are in good condition, it will not be necessary to change them since the removal of amalgam is not highly recommended because mercury particles may be released during the removal process. In addition, the tooth structure may be compromised and weakened as the tooth will have a large cavity to retain the material.
The durability of filling materials will depend upon different factors. The appropriate material of an amalgam filling should ensure the health of the tooth, the mouth, and the person. Currently, the FDA recommends avoiding amalgams as much as possible since newer materials are based on resins and glass ionomer, whose durability has been improving in recent years. However, these materials still cannot compete with some of the characteristics of amalgams, especially in large cavities in posterior teeth. In spite of this, resin-based materials require less tooth tissue removal to be placed. On the other hand, given that the color is so similar to a natural tooth, it is a further advantage, especially in anterior teeth.
