best dentists for complicated fillings?

[elusiveat]

I just got back from my first cleaning since before the pandemic, and learned that I have a cavity in the root of one of my molars that will evidently be complicated to fill. I like my dentist okay, but I want to do absolutely everything I can to avoid the filling failing and needing to get a crown.

Who are the best dentists in the area for this sort of thing?

(and thanks)
