There are other types of dental fillings that you can use instead of dental amalgam if you think you may be allergic to its mercury component.
Resin composite is a tooth-colored material made out of resin compounds and powdered glass. When they were first introduced in dentistry, they were not strong enough and was limited to the front teeth. Today, resin composites are stronger and can be used for molars, although they need earlier replacement since they don’t last as long as metal-based fillings.
Glass iomer cement is made out of glass and is a tooth-colored material like resin composite. However, it is not used for long-term fillings because glass iomer breaks easily.
Other metals like porcelain and gold are also used as fillings, especially for bridges, inlays, crowns, and veneers.
