No you are not the only one that worries about needing dental work soon after hip replacement. They stressed the dangers of infection very clearly to me pre op. I usually go for dental cleaning every three months, so I am not feeling good about waiting the minimum 6 months. And I have thought to myself I sure hope nothing goes wrong right now. I did read an article about where they did a study of so many people who had dental work done shortly after hip surgery and compared to those that had no surgery, and the rate of infections was nearly identical. In fact some organizations have dropped the recommendations about the antibiotics. But old protocols take a long time to change, so most Drs. still advise them. You did have antibiotics so I am sure you won't have problems. I would think the risk is very low. Hope you don't worry too much. I know stress is not good for us. Good luck!
