I had a pancreas transplant in 2005. Part of the aftercare was an antibiotic prescription to take as a prophylactic before dental appointments. It was explained to me that this was necessary to prevent/treat infections I might encounter with dental procedures since I’m immune suppressed. It wasn’t amoxicillin since I have an amoxicillin allergy but I don’t remember what it was. This went on for several years before routine dental cleanings/exams. At some point I broke a crown, had to find a new dentist (insurance change) to repair it. Antibiotic prophylaxis was no longer a consideration. This past summer I found out I needed a root canal in a different area. The endodontist (another new provider due to insurance change) prescribed an antibiotic for pain I was having not for a prophy. I got the root canal and followed up with a permanent filling. I’ve had 3 new providers this past year and no more antibiotic prophylaxis. Maybe this is because I am so far past the original transplant and I am still here, thank God!
