There are different materials used in dental restoration, which are the following:
1. Amalgam
Amalgam is one of the strongest materials used in dental restoration, which is basically a mix of several metals, among them silver, tin, mercury, and copper. There has been some controversy over the safety of amalgam, but it is only purely speculation and has not been supported by any kind of scientific background.
2. Porcelain
This is a more expensive material, which is chosen because of it’s similar hue to the teeth. However, under certain circumstances, it may break.
3. Composite resin
Made out of acrylic plastic material combined with glass or quartz fillers, composite resin is relatively sturdy, but it’s greatest weakness is its propensity to discolor faster.
4. Gold and base metal alloys.
These are very sturdy, but the downside is a metallic sheen that might serve as an aesthetic deterrent to patients.
