Which material is known for its durability in dental fillings?

Dental amalgam is well-known for its durability in dental fillings. It is made from a mixture of metals, including silver, tin, copper, and mercury, which gives it its strength and longevity. Amalgam fillings are particularly effective in areas of the mouth where there is significant pressure from chewing, as they can withstand these forces without breaking down over time. Because of their robust nature, amalgam restorations are often used in posterior teeth, which experience higher bite forces.

In contrast, glass ionomer and composite resin materials, while useful for various applications, may not provide the same level of durability as amalgam in high-stress areas. Glass ionomer is often chosen for its ability to release fluoride, which can be beneficial for surrounding teeth, but it is generally more prone to wear and less durable than amalgam. Composite resin offers aesthetic advantages, as it can be color-matched to natural teeth, but it is typically less durable compared to amalgam and may require more frequent replacements, especially in posterior areas. Silicate cement, although used historically, has largely been replaced by other materials due to its lesser strength and durability when compared to amalgam.

Therefore, the durability of dental amalgam makes it the preferred choice in situations where lasting strength
