After tackling a controversial issue in the dentistry world, let’s go to something more safer: dental composites. As mentioned in an earlier post, this is just one of the direct restorative materials used today. Unlike the dental amalgam, this does not contain mercury, rather it’s made up of high molecular weight misnomers that when cured create a rigid cross-linked polymers: plastic.
Plastic needs a lot of support, for this reason certain modifiers and fillers have been added in to improve its basic components. Just some of the add-ons are: quartz, zinc, glass, zirconium, silica, barium, and stronium. Without these your teeth will break apart while chewing gum.
It’s not as tough as the amalgam, but it’s safer.
