I told my Dentist and he hardly knew what CD was, I had to explained to him as he asked questions, and why it happens and it was annoying kinda.
I told him the meds I was on and he never heard of them (I went this week btw). He cleaned my teeth, polished, all went well. I came back the next day later for cavity filling, he gave me novacaine needle and I was ok after, and it's been 2 days later so I guess i'm all good. I guess my immune system isn't too bad yet as i've only been on Imuran for a week. Also, where he put needle is healed already, and it only hurt for a few hours after.
