Thank you for your response to my question. I made the mistake in my original question of saying this was my "first' permanent bridge session. Actually, some weeks earlier in my real "first" session with him, my dentist took preliminary xrays of the anchor teeth. In the second session, (the one my question referred to) he used Nitrous-Oxide and Novocain, prior to performing the RCs, because it was his original intention to prepare my teeth for the placement of a lower bridge. It was then, during this preparatory session, that the teeth abscesses "came to light". Also, it turns out that what caused my discomfort/pain problems was the Dental assistant or tech did not allow the cement to dry well enough and did not do a good enough job "finishing up" or cleaning/smoothing the excess cement on the back of some of my teeth. Because of it not being allowed to set right, the crown (entirely) came off 3 nights later. They replaced it Yesterday. This time a different technician did the work. Finally, this time it seems (knock on wood) smoother and relatively more comfortable.
This is all very odd. Novacaine will not numb an abcessed tooth, and an abcess is caused by infection and antibiotics should have been his first course of action. He should have xrayed the anchor teeth prior to starting anything and he would have seen any abcess/infection "if" it was there. Sounds like he found a way to make a quick buck to me! My temporary bridges looked good, and if your feeling something sharp and are in pain call your dentist and let him know. It sounds like the crowns are too long. Call your dentist and go from there. Take care.
