Dr Tran’s Dental Practice Kingswood offers complete root canal treatment over several visits to our Penrith clinic. The first step involves cleaning the canal and enlarging and reshaping it for the following treatment stages. At this point, our highly skilled dentist will place a dental dam to isolate the tooth from the rest and clean and dry it during the procedure. After this, we will precisely access the inside of the tooth, creating an opening at the top.
