Had to have crowns on 2 lower molars side by side which had already had root canals. I paid for porcelain fused to metal. The dentist glued the very back one in first and then had trouble squeezing first molar crown in and getting it to fit. Finally, he got it in and had to adjust the bite on them. When he finished, he had to drill the porcelain crown in the very back down to the metal on top to get the bite right and I had a small spot of metal on top of my newly paid for porcelain crown showing. Hygenist mumbled something about him not doing something right and told me not to say anything about her saying this. I don't know if he got the crowns mixed up or put them on in the wrong order. I was not happy having to leave with a metal spot on my new crown after paying so much for it. Any comments appreciated?
