Oh, I know they are great. I had a sinus issue going on and it was one of those super-doc’s there that found the problem. My idiot dentist up here while doing 3 root canals decided to drill through my jaw and into my sinus cavity. The posts of the crowns are sticking out inside of my sinuses. I was in perpetual agony for 3 years before this doctor found it. My niece is one of the directors of the family medicine division and my son works for the school.
They pay a lot of students to allow them to do medical research on them too so… there’s a lot of good but God only knows the long term effect of some of that stuff on people.
