Get a second opinion on work. I went in for a cleaning and was impressed with the place. During cleaning I was told that I must get some fillings and other deep cleaning procedures @$800. They explained payment options, I declined. I called for an appointment 6 months later for another cleaning and they refused to take me unless I bought the treatment they pitched me on the previous visit. Naturally I had to get a second opinion so I went somewhere else.
I saw another Dr. and found San tan dental to be completely full of it.
