The tooth is first cleaned and prepared by removing any decayed or damaged tissue The glass ionomer filling material is then mixed and placed into the cavity, where it is shaped and molded to match the natural contours of the tooth Once the filling has hardened, it is polished to ensure a smooth and comfortable fit.
