I had a horrible experience with Cdiff starting last October. I had 4 relapses with meds & had A FMT on February 28th. I’m in remission I think now. My tummy is still not right, but probably never will be. Last week I got some ulcers on my upper gums. They aren’t sore & don’t bleed when I brush. I have porcelain veneers on my six front teeth. I’ve had them almost 4 years & no problem at all. I went to the dentist & he said it was infection. He deadened them & went up under my gums & tried to clean up the infection. He said my teeth were very clean. I use a water pic. I was told that stomach issues could cause this. Generally he would have given antibiotics but since I’m just recovering from Cdiff we opted not to. They look better, but I’m nervous about all this due to possibly as infection that could come back or get worse. Has anyone of you that have had Cdiff had mouth ulcers .?
