Dr. Ortner re-did a root canal that failed after 33 yrs. He was up front about the liklihood of success (60%). He is very calming, explains everything, looks you in the eye, smiles and touches you (appropriately) on the arm while talking. He did his best to minimize my anxiety and make it a relatively pain free experience. This is very expensive care in a very posh atmosphere by a very good endodontist. His staff is friendly and helpful.
