Hello, there are different ways to fill teeth in different situations. If a tooth has a hole, it can be filled with special dental materials. Filling materials include amalgam, zinc phosphate cement, zinc polycarboxylate cement, glass ions, light-cured resin and so on. If it is a tooth defect or only a part of the teeth, porcelain braces can be made to repair the teeth after treatment. If a tooth is missing and falls off, there are three ways to repair it. One is removable partial denture, which can be removed by itself and needs to be removed and cleaned. The second is porcelain teeth. Generally, it is necessary to polish the front and back teeth of the missing teeth and repair the missing teeth by bridging. It's a fixed denture. You can't take it off by yourself, and you don't need to take it off for cleaning. The third is dental implant. It is to implant artificial root (pure titanium implant) in the place where the tooth is missing, and then make porcelain teeth on the artificial root. Don't take it off yourself.
