1 /5 Laura Haynes: When I had an allergic reaction to a temporary crown, she said "its always something with you". She used some kind of glue instead and that cracked off, leaving a jagged edge which cut into my tongue. I called to see what to do and she was about to go on vacation so she told me to put wax on it. Its the tooth in the very back, there is no way wax will stay on. She left and I couldnt eat for a week. I had to go to another dentist just to get the sharp edge filed down. Then the crown she replaced broke off after a few weeks. Awful experience. Waste of time and money. I cant afford to get it fixed so I have to eat on one side of my mouth. Thanks a lot.
