I'm no dentist but as a patient I know I would never sign up to let a dentist do all that to me in one shot. However, that said, all this 'expert' tells me is that he himself wouldn't be able to do it well. I think testimony from a doctor who actually saw the work and weighed in on the qualty would be more interesting than some 'expert' who is just blathering.
In case you haven't noticed, I'm sick of being manipulated by anonymous 'experts' who are dug up to mouth the opinion of a lawyer or a politician or a reporter as part of their Argument from Authority fallacy.
My last root canal and crown took 3 visits in total...had to first get a temporary crown. The amount of work done to this patient in one visit doesn’t ring true.
I think the most I’ve ever had done at once is one crown prep and one filling or maybe two fillings. Nobody has ever proposed more.
That poor patient, in addition to all that shoddy work probably has ruined TMJ joint, muscles and tendons. I suffer from TMJ maladies and it is horrible.
I would say the DMD called as a witness is more than just blathering. It would appear he has been called as an expert witness before.
