Why Antibiotics are Necessary Before Dental Work After Hip Replacement: Explained


So, you’ve recently undergone a hip replacement surgery and now you’re wondering why your dentist is asking you to take antibiotics before any Dental work. Well, let me break it down for you in simple terms. When you have a hip replacement, there is a risk of bacteria traveling from your mouth to your bloodstream during Dental procedures, which could potentially cause an infection in your new hip joint. By taking antibiotics before Dental work, you’re helping to prevent any potential complications and ensuring the success of your hip replacement surgery. It’s just a precautionary measure to keep you safe and healthy – better safe than sorry, right?



If you’ve recently had hip replacement surgery, you may be surprised to find out that your dentist is requiring you to take antibiotics before any Dental work. This is because of a serious infection called infective endocarditis.

Infective endocarditis is a dangerous infection of the heart lining or valves, caused by bacteria entering the bloodstream. People with certain conditions, like a history of heart issues or recent joint replacement surgery, are more at risk for this infection.

During Dental procedures, bacteria from the mouth can enter the bloodstream through small cuts in the gums. This can lead to infective endocarditis, especially in those with prosthetic joints like a hip replacement, where bacteria can attach to the artificial joint and cause an infection.

To lower the risk of infective endocarditis, the American Dental Association advises individuals with prosthetic joints to take antibiotics before Dental work that may cause bleeding, such as cleanings or extractions.

While there is debate about the use of antibiotics before Dental procedures due to the risk of antibiotic resistance, the benefits of preventing infective endocarditis outweigh the risks in this case. It’s important to follow your dentist’s advice and take the prescribed antibiotics properly to protect your health.

In conclusion, if you’ve had hip replacement surgery, don’t skip the antibiotics before Dental work. By following your dentist’s recommendations, you can safeguard your health and ensure the success of your hip replacement surgery.
