What Are Composite Fillings Made Of?
A staggering 92% of adults aged 20 to 64 have had cavities in their permanent teeth, says the National Institute of Dental and Craniofacial Research. With such a high number, the need for composite dental fillings that look natural has shot up. But, what are composite fillings made of? These amazing fillings combine acrylic resin and fine glass particles. This mix makes tooth restorations strong and matches them with your natural teeth.
Unlike silver fillings, tooth-colored fillings are mercury-free. This is a big plus for people who worry about safety. The acrylic resin has glass quartz, silica, or ceramic particles added in. This mix looks good and is strong. Plus, these fillings don’t have the mercury vapor issue, which can harm brains and kidneys if levels are too high.
But, there’s more to these fillings. Some people worry about Bisphenol A (BPA) in them. Today’s dentistry often skips BPA in composite fillings. And if it’s used, the American Dental Association says it’s a tiny amount that’s safe. So, composite fillings are not just good-looking. They are also a safe option.
