What were old dental fillings made of?

How did Romans have perfect teeth?That wasn’t the only surprise for the researchers: their analysis also revealed that the people of Pompeii had nearly “perfect teeth,” ANSA reports. A low-sugar diet, rich in fruit and vegetables — along with fluorine that was present in a local water source— gave them their pearly whites.

French physician Pierre Fauchard, often considered the father of modern dentistry, was one of the first people to cite sugar as a possible cause of cavities. In the 1890s, W.D. Miller, the world’s first oral microbiologist, said he believed bacteria in the mouth could dissolve tooth structures.
How did the Romans deal with cavities?
There were few preventive treatments, with most Romans using a toothpaste that was derived from urine. And if Romans started to develop tooth decay, there were no fillings, dental crowns. The only treatment was the extraction of the tooth, with only wine for anesthesia, and no dental implants to replace them.
Can you still get silver fillings?

Stainless steel crowns are silver caps attached to molars. They cover the back teeth and preserve more of the tooth structure than other varieties of crowns. They withstand biting and chewing forces well and rarely chip or break.
Are Porcelain fillings toxic?
Porcelain is tooth-colored, stain-resistant, mercury-free, and BPA-free. And unlike amalgam and other alternatives, porcelain fillings may last up to 20 years. However, when porcelain is fused to metal, the heavy metals may seep from the filling substructure into your oral cavity, contributing to heavy metal toxicity.
Is it safe to remove mercury fillings?
