I went to Cambridge Dental several different times and had much the same experience as the poster that wrote the "Dangerous" post.
Infectious disease is my forte, and I cannot recommend this dental facility. I, too, found glaring deficiencies in infection control.
However, the quality of workmanship and bedside manner were average. And there was always a problem with my bill, even though I made my copay every time. They never did get it right, and it was aggravating and very unreliable.
I won't be back.
