Don't go here if you're paying cash. That 89 dollar coupon is a scam. They told me I needed a "deep cleaning". "How much is it?" I asked. "That'll be shown in your treatment plan." So I go to the front desk, and the poor secretary hands me a treatment plan for a three visit, FOURTEEN HUNDRED DOLLAR cleaning. I laughed at it, and then walked out. If you're uninsured in this state, literally the only place you can get a decent dental cleaning is a dental school.
***UPDATE*** I was visiting friends in California and decided to pop in to my old dentist there. I explained that some nutjob dentist in Arizona (Imagine Dental) wanted $1400 to clean my teeth, as I had gone about a year without a cleaning. Hygienist looked at my teeth, said, "There's just a little excess buildup in the back, nothing I can't handle." Did the work in one cleaning. Cost: $95. Even if you have insurance, expect to come in here for extensive and expensive treatments you might not need. Absolute scam, though I'm not sure if there's a place in Arizona that isn't a scam.
