I do not know the answer to this one, but I do know who you should not go to. I am not sure if the dentist is a Delta Dental provider or not, but do not go to Santa Fe Dental in Edmond. They will over charge you for procedures and try to get you to do things that are not necessary. I actually use Dr. Terry Smith in Guthrie, and have been quite pleased with his service...but I will never go back to Santa Fe Dental. They ripped me off and caused me all kinds or financial problems. D.
