Was this a good idea to fix my teeth this way? (Photo)

Dentist before suggested a bridge, new Dentist said it can't be done and to put 2 crowns on, had temp crowns today but can't chew properly due to too much on the back of the front tooth near the gum, my bottom teeth hit the back of the crown which stops me from chewing small bits, Dentist said she can't take too much off it and basically said i'll have to put up with it for 3 weeks, do I ring them back tomorrow and say I can't chew properly or do I just put up with it? and advice...
