Hi Lyndsay
I don't know which book your dentist reads. I had my Prodisc surgery in 2004 in the UK and was told that there was no need for antibiotic cover prior to dental treatment following my double total disc replacement.
I have had dental treatment since surgery without antibiotic cover and have had no problems with infection.
The advice from your surgeon does sound ambiguous, I guess that he means that as you have already started you may as well finish the preventative course, even though it wasn't necessary. Is it just three doses you have been prescribed?
If I can find the research I did myself a few years ago about the same issue I will forward it to you. Your surgeon has given the same info as mine, ie antibiotic cover is not needed. I'd go with what they say but at the end of the day the decision is between you and your dentist.
Regards
Lynda
