Dr. Dillard peformed a root canal and crown. Within 2 months the tooth broke completely in half below the gum line. My wife, who is an RN saw his office and said that I was not to go back due to the unsanitary appearance. Dr. Dillard does not always wear a mask. He came in to work on my tooth one day and was very aggitated at someone leaving a very unpleasant experience for me. I went to another dentist to see about repairing my broken tooth but quickly learned I would need an implant as this tooth was not repairable. Now I have been turned over to a collection company for the $200 balance I had but I have sent several registered letters requesting a full refund to get my tooth fixed. His staff was fabulous but as for a dentist his work for me was obviously very poor. For my tooth to break in half as quickly as it did, he must use substandard products, too.
