I was visiting from out of town and had a toothache. Found On Call Dental on the Internet and was able to walk-in, same day without an appt. The lady at front desk was very nice. I was seen by Dr. Greding and his Assistant. After x-rays it was determined that I had a very bad cavity in back molar and was given a couple options. One, to try to save the tooth with a root canal, but no guarantee that would work until he got in there to see how bad the decay was. The other option was to pull the tooth. Dr. Greding was fabulous about going over my options and explaining in detail what those option details were. Because I am retired on a fixed income without dental insurance I chose to have it pulled. Unlike other experiences, I did not get any push back about my decision. I absolutely will recommend Dr. Greding and On Call Dental to my family and friends here in the Phoenix area. Dr. Greding even took the time this morning to call me to make sure I was doing okay. 5-Star rating for sure! Thank you to all that helped me.
