Steps Involved in Filling of a Tooth
- First, the area around the tooth is made numb with a local anaesthesia.
- Next, the decayed area is removed using an air abrasion instrument or laser.
- Once the decay has been removed, the space for the filling is prepared by cleaning the cavity of bacteria and debris. If the decay is near the root, a liner made of glass ionomer, composite resin, or other material may be put first to protect the nerve.
- Finally, after the filling is in, it is given a finish and polished.
