Antibiotics with dental care

[Guest guest]

I had my first dental appointment last month after my surgery and took the

antibiotics my dentist prescribed. She wanted something in writing for my chart

from my OS regarding how long he wanted me to take antibiotics. From what was

faxed, Dr. T. wants me to take antibiotics before dental work

indefinitely/forever. My next appointment with my surgeon isn't till Feb, and I

plan to ask about this then. I have no problems complying with it, but I've

heard that other TKR patients take antibiotics for more like two years

post-surgery. Right now I don't know if this is standard protocol with all his

patients.

What has everyone been told by their surgeons as to how long to take antibiotics

prior to any dental work?
