Antibiotic prophylaxis (pro-fuh-LAX-is) is when patients take antibiotics before dental treatment to prevent infection. This step is recommended for very few patients.
In the past, anyone who had an orthopedic implant like a hip or knee replacement, or metal plates or rods, used to take preventive antibiotics before certain dental treatments. This is no longer recommended in most cases.
Also, a small number of people with specific heart conditions might be prescribed antibiotics before some dental treatments to help prevent a serious heart infection.
This brochure explains both the possible harms and benefits of taking antibiotics before dental treatment. Use it to help talk with your dentist, physician, orthopedic surgeon or cardiologist to understand whether taking preventive antibiotics is right for you.
People who take antibiotics before some dental treatments usually do so because research suggests that antibiotics may help prevent certain types of infections.
Many people think that there are no harms associated with taking an antibiotic. But, as with any treatment, there are both benefits and potential harms. Because infections after dental treatment are not common and taking antibiotics as a preventative measure may cause a problem rather than defend against one, they are not recommended for everyone.
Here are some problems that can happen with taking preventive antibiotics:
Also, there is scientific evidence that most dental treatment procedures are not connected with prosthetic joint implant infections.
Some people with certain health conditions are told to take antibiotics before having certain dental treatments.
For a small group of people, there’s concern that bacteria in their bloodstream can cause an infection of their heart lining or valves. This infection is called infective endocarditis (end-oh-car-DYE-tis).
The American Heart Association only recommends preventive antibiotics for people who would be at risk of more serious disease if they developed a heart infection after dental treatment. This affects a very small group of people with specific types of heart conditions.
If you have one of these heart conditions, your dentist, physician or cardiologist may recommend that you take an antibiotic before certain dental treatments:
You may be prescribed antibiotics before certain dental procedures to prevent joint implant infections if you
have experienced previous complications from a joint replacement surgery. Or, a person with a total joint replacement might take antibiotics if they are at increased risk of infection because of other drugs or diseases.
Talk to your dentist or orthopedic surgeon before any appointment. They can best determine
if you might benefit from taking antibiotics before your planned treatment.
Antibiotics should always be prescribed by a health care provider and used as directed. If you have any questions, or if there are any changes in your health history or the medicines you take, let your dental office know so they can update your records.
Antibiotic prophylaxis before dental treatment is recommended only for patients at highest risk of developing infective endocarditis—a serious heart infection. This includes individuals with prosthetic heart valves, history of previous infective endocarditis, certain congenital heart defects (particularly unrepaired cyanotic defects or repaired defects with prosthetic material), cardiac transplant recipients who develop heart valve problems, and those with certain heart conditions involving prosthetic material. American Heart Association guidelines have significantly narrowed this list in recent years after research showed antibiotic risks often outweigh benefits for most patients. For dental procedures involving gum manipulation or perforation of oral tissue, high-risk patients typically take a single dose of amoxicillin 2g (or alternative if allergic) 30-60 minutes before appointment. Your physician or cardiologist should provide guidance specific to your condition.
Most patients with joint replacements do not need antibiotics before routine dental procedures. The American Dental Association and American Academy of Orthopaedic Surgeons concluded dental procedures are not associated with prosthetic joint infections and prophylactic antibiotics do not prevent such infections. However, antibiotic premedication might be considered for patients with history of complications from joint replacement surgery or those with multiple risk factors including compromised immune systems (from diabetes, rheumatoid arthritis, cancer treatment, or immunosuppressive medications). In these specific cases, it’s most appropriate for your orthopedic surgeon—not your dentist—to recommend the antibiotic regimen and write the prescription. Routine procedures like cleanings, fillings, and even most extractions don’t require premedication for the vast majority of joint replacement patients. Consult both your surgeon and White Pine Family Dental to determine if premedication is appropriate.
Taking antibiotics when not medically necessary carries several significant risks often outweighing uncertain benefits. Common side effects include nausea, upset stomach, diarrhea, and allergic reactions ranging from mild rashes to life-threatening anaphylactic shock. More seriously, unnecessary antibiotic use contributes to antimicrobial resistance—creating drug-resistant “superbugs” making common infections like strep throat, urinary tract infections, and pneumonia harder to treat. Patients over age 70 face increased risk of adverse reactions to certain antibiotics. Additionally, antibiotics can cause Clostridium difficile (C. diff) infection, leading to severe intestinal problems and diarrhea. The medical community increasingly recognizes routine daily activities like tooth brushing and chewing also cause bacteremia (bacteria in bloodstream), yet we don’t take antibiotics for these activities. Overuse of prophylactic antibiotics before dental procedures has contributed to widespread public health concerns about antibiotic resistance.
Consult with both your primary care physician or specialist (cardiologist, orthopedic surgeon) and your dentist to determine if premedication is appropriate. Bring a complete list of your medical conditions, surgeries, and current medications to your dental appointment. Conditions previously requiring antibiotics—like mitral valve prolapse, rheumatic heart disease, or routine joint replacements—no longer need premedication under current guidelines. White Pine Family Dental follows the latest American Dental Association and American Heart Association recommendations. If your physician prescribed antibiotics for dental procedures in the past, confirm this is still necessary, as guidelines have changed significantly. For patients with genuine indications for prophylaxis, your physician should provide written protocol specifying which antibiotic, dosage, and timing. Don’t rely on outdated information—medical guidelines evolve based on new research, and what was recommended 10 years ago may no longer apply.
If you require antibiotic prophylaxis, take the medication 30-60 minutes before your dental procedure to ensure adequate blood levels during treatment. The standard regimen for preventing infective endocarditis is a single oral dose of amoxicillin 2g taken one hour before the procedure. For patients allergic to penicillin, alternatives include cephalexin 2g, azithromycin 500mg, or doxycycline 100mg. If you forget to take the antibiotic before your appointment, it can still be administered up to 2 hours after the procedure, though pre-procedure dosing is preferred. Never split antibiotics across multiple days for prophylaxis—it’s a single loading dose designed to cover the brief period of potential bacteremia. If you have back-to-back dental appointments on consecutive days both requiring prophylaxis, you must repeat the antibiotic dose before the second appointment. Contact White Pine Family Dental if you have questions about timing or experience side effects.
