Tooth filling is done when tooth is decayed and cavity is formed. Although there are different types of fillings available, most common and popular one is composite filling/white filling. This has many advantages and is more esthetically pleasing as it restores the tooth to its natural shape and color. The dentist will remove the decay and clean the cavity using a drill. Then place the white filling, layer by layer until the cavity is filled. Special light is used to speed up the hardening process of each layer. Once the cavity is filled and filling material is hardened, it is shaped and polished.
These fillings can usually be completed within a single appointment.
