my dentist assigned to me by my dental plan did several horrible things yesterday when he said i needed 4 root canals. he was wrong about one, i had prior dental/oral surgeon opinions on that. i had to tell him that tooth was fine. so i ended up having 3 root canals done on my front teeth. he lied to me twice about the meds he was giving me. scariest, i have a mitral valve prolapse and he realized mid-procedure they didn't pre-med me! so right after they gave me 4 penicillin. he wouldn't give me anything for pain and also refused to give me an on-call number as it was a Friday and i wanted to be sure i had contact info for the weekend if i ended up in pain. now it's Saturday, i have to work, and i'm hurting bad; taking the advil & antibiotics but i'm still in pain. and FURIOUS.
