The importance of teeth is self-evident, but it does not have the ability to repair itself like skin. Once accidentally injured or tooth decay, we must go to the hospital to repair the damaged teeth. I believe that most people have dental filling experience, so what exactly is the stuff that sticks to our teeth?

The history of dental fillings is actually quite long. Our ancestors paid great attention to oral hygiene and health from a long time ago. If the ancients lost their teeth, there were dentures. Professional doctors appeared in the Song Dynasty, and the records of filling teeth can be traced back to the Tang Dynasty.
