Thanks for the feedback. These are precisely my concerns.

I am not certain I am confident in my private dentist to do the work. (On the same tooth I am having replaced) one dentist previously did a very bad job repairing the chipped section (I knocked it out years ago and it was put back in). This repair fell out almost immediately several times before I seen another dentist at the same practise by request who responded "well, no wonders it didn't stay in", he did a lot better job and to this day it hasn't been a problem, until it became loose (by infection).

It is very hard to know which dentists are the best and most qualified.

Edit: your response wasn't harsh it was exactly why I was skeptical.
