Teeth can be filled with gold; porcelain; silver amalgam (which consists of mercury mixed with silver, tin, zinc, and copper); or tooth-colored, plastic, and materials called composite resin fillings. There is also a material that contains glass particles and is known as glass ionomer. This material is used in ways similar to the use of composite resin fillings.
we use a local anesthetic to numb the part around the tooth to be filled. Next, a drill, air abrasion instrument, or laser will be used to remove the decayed area. The choice of instrument depends on the individual dentist’s comfort level, training, and investment in the particular piece of equipment as well as location and extent of the decay. We will probe or test the area to determine if all the decay has been removed. Once the decay has been removed, then we will prepare the space for the filling by cleaning the cavity of bacteria and debris. If the decay is near the root, our dentist may first put in a liner made of glass ionomer, composite resin, or other material to protect the nerve. Generally, after the filling is in, our dentist will finish and polish it.
