Dr. O'Leary replaced two crowns. Most of the routine work was done by technicians. Work was sloppy. I still have the crowns in my mouth that are rough to the touch. For the cost of these, a few minutes care to polish the crowns before cementing them in my mouth would have been preferable. One of the crowns, although apparently fitting well before cementing, was actually badly seated during cementing. It still fits badly. I never returned. They proved themselves to be incompetent. A waste of my money. Most dissatisfied.
