This recommendation, known as prophylactic antibiotics, was a broad recommendation that's no longer in place. In fact, the American Dental Association released guidelines in 2015 stating that, for most people, prophylactic antibiotics should not be recommended before dental procedures to prevent prosthetic joint infection. For most people, the risks of taking prophylactic antibiotics — including infection, allergies and the development of antibiotic resistance — may outweigh the benefits.
There are some caveats to that recommendation. In particular, people who are immunocompromised, have uncontrolled diabetes or a have a history of infection after joint replacement should take antibiotics before dental procedures. However, discuss this with your orthopedic surgeon or primary care doctor, who can help you weigh the risks and benefits.
While joint replacement may no longer be a reason to recommend antibiotics before dental work, there are other circumstances in which antibiotics may still be advised. If you're considered at high risk of infection in the inner lining of your heart chambers and valves (infective endocarditis), your cardiologist may prescribe an antibiotic before dental work. This includes people with prosthetic heart valves or a history of infective endocarditis, as well as people with certain congenital heart diseases.
