To treat a cavity our dentists will remove the decayed portion of the tooth and then "fill" the area on the tooth where the decayed material was removed. Fillings are also used to repair cracked or broken teeth and teeth that have been worn down from misuse (such as from nail-biting or tooth grinding).
What Steps Are Involved in Filling a Tooth?
First, our dentists will use a local anesthetic to numb the area 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 the location and extent of the decay.
Next, our dentists will probe or test the area to determine if all the decay has been removed. Once the decay has been removed, They will prepare the space for the filling by cleaning the cavity of bacteria and debris. If the decay is near the root, our dentists 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 they will finish and polish it.
Several additional steps are required for tooth-colored fillings and are as follows. After your dentist has removed the decay and cleaned the area, the tooth-colored material is applied in layers. Next, a special light that "cures" or hardens each layer is applied. When the multilayering process is completed, our dentists will shape the composite material to the desired result, trim off any excess material, and polish the final restoration.
